KISSsoft 03-2014 KISSsys. 1.2Definition of project folder KISSsys uses projects to manage the files. Project folder simply defines where KISSsys models and the respective KISSsoft files are saved. Before a KISSsys model can be opened or created, the project / folder where the model will be saved is to be defined. File Open project folder, the project folder will be defined. If there is no Project folder defined everything will be saved in the default folder. E.g. Users KISSsoft. Inthefollowingfigureitisshowntheprojectfolderforthistutorial.InthiscasethefolderisC:\Programme\KISSsoft 03-2014\KISSsys\Tutorial. After the selection, this is confirmed and KISSsys opens.

Surface after opening a model in KISSsys Note that models should be opened only from the current project folder. 25.07.20146 / 31 Part II, Using an Existing Model 2Toolbars and views 2.1Views in KISSsys 2.1.1Views and windows KISSsys features the following views: MenuShort-cut IconTabsUserInterface3D-View Tree structureMessagesTablesSchematic Figure 3.Views available in KISSsys TheClasses,theModel(treestructure)theTemplates,theMessages,theKISSsoft(Messagesfromthe KISSsoft calculations) and the Diagram can be shown or hidden by using the menu View: Figure 4.Show or hide tree structure, messages and schematic 25.07.20147 / 31 The tables, user interfaces and 3D view can be minimised, restored and closed. Using the menu Window, navigating between the windows is possible. A closed window can be shown by a right mouse click on its corresponding element in the tree structure and then selecting Show. Another way to reopen the window is to double click on the element in the tree structure. 2.1.2Connection between 3D-View, schematic and tree structure If an element in the tree structure is selected (left mouse click), it is highlightedred. Also, in the 3D view, a local coordinates system is shown in the centre of the element.

Figure 5.Selecting an element in the tree structure highlights it in the 3D view If an element is selected in the schematic, it is highlighted in the tree structure and in the 3D view. When moving the cursor over the elements of the schematic, the name of the respective element is shown. With a right mouse click, the element can be modified if you are in Administrator mode (see after). Figure 6.Information about the element in the schematic 25.07.20148 / 31 2.1.3Using the 3D-View Inthe3Dview,thegearboxcanberotated,movedandzoomed(left,centre,rightmousebuttons respectively). 2.1.4Refresh All Data and graphics are updated when the Refresh All button is pressed. This command results in an update of for example the 3D view after having changed some parameters such as the tip diameter of a gear or that the power flow is highlighted in the schematic after the calculation of the kinematics. 2.2In- and output of data In the user interfaces and the tables, the following text elements are used FeatureTypeUse BlackOutput / TextUsing black, results are shown that change with the analysis. Comments are also in black. RedInputIn these fields, values can be entered directly or they can be chosen from an underlying list (double click). The values entered or chosen are then stored in the respective variables. Grey backgroundFunctionsFunctions are executed through double-click (left mouse button) 2.3Starting KISSsoft analysis Through the tree structure, the KISSsoft analysis can be started by a double click on the respective symbols as shown below: Figure 7.Symbols of KISSsoft analysis 25.07.20149 / 31 3Use of the model 001-KISSsysTutorial 3.1Calculate kinematics The kinematic analysis is started through double click on the function Kinematic. All speeds, torques and bearing forces are calculated. Based on the input speed, the gear data and the output torque, the resulting reduction i tot, the input torque and the output speed are calculated and shown: Figure 8.Results in the UserInterface after execution of kinematics analysis The speed at the input and the torque at the output can be defined directly. Note that the sign of the torque defines the direction of the power flow. After having changed the values for input speed and output torque, the kinematics should be analysed again by executing the function Kinematic in order to get the corresponding results. 3.2Analysis of root and flank safety factors Onexecutionofthe functionStrength(doubleclick)thekinematicsarecalculatedagain, followedbythe strengthanalysisofthegears,bearingsandshafts.Theresultingsafetyfactorsfortherootandflankare shown in the user interface (based on a lifetime of 20000h): Figure 9.Output of resulting safteies fr root and flank 25.07.201410 / 31 If the analysis is to be performed for a different lifetime, the required lifetime should be changed in KISSsoft. Using the function GP1, access to KISSsoft is available where the lifetime can be changed from 20 000h to e.g. 30 000h (repeat for second stage). In order to have the new value accepted, Calculate or F5 has to be pressed, then exit KISSsoft: Figure 10.Changing the required lifetime After that, the calculation of the safety factors can be repeated by double click on Strength. 3.3Changing gear data, earing data and shaft geometry The gears, shafts and bearings can be changed in KISSsoft in the usual manner. For this, double click on a KISSsoft symbol in the tree structure in order to get into the KISSsoft analysis of the desired element. Here, forexamplefinesizingofgearscanbeexecutedorthetypeofbearingmaybechangedinthebearing analysis. In order to make the changes permanent, Calculate F5 has to be pressed before exiting KISSsoft. The number of elements to be arranged on a shaft may only be changed in KISSsys directly. Note that elements (gears, bearings, couplings, ) shown in the graphical shaft editor must not be removed or added since the number of elements on a shaft is defined in the tree structure within KISSsys. 25.07.201411 / 31 Part III, Building a model 4Task In KISSsys, a model of for the strength analysis of a two stage helical gearbox with analysis of the gears, bearings and shafts is to be built. This model is to be used for analysis or dimensioning such systems. In the end, the model built will correspond to the model KISSsys-Tutorial-001. 4.1Structure of the system The new system is assembled from elements such as gears, shafts, etc., and the corresponding KISSsoft calculations. These elements are taken from a library, called "Templates". 4.2Sketch of the system Before starting with the model, it is recommended to sketch the system. This will be used later for the element name definition. Figure 11.Schematic 4.3Start KISSsys Firstanewprojectfolderisdefined,e.g.C:\MyTutorial.Then,startKISSsyswiththisfolderasproject. KISSsys is then opened with an empty model. Using FileSave from the menu, this file is given a name, e.g. KISSsys-Tutorial-001. In order to be able to build a new model, KISSsys should be used in the administrator mode, which is activated by pushing this buttonor in the menu Extras: 25.07.201412 / 31 Figure 12.Change to Administrator mode If the option Administrator is not available, the respective license is missing. Contact KISSsoft AG. 4.4Loading the templates The Templatewith the standard default library element, will be open automatically when changing to the Administrator mode. If a specific template shall be opened, then go to File Open Templates. In the Templates, all elements available in KISSsys are now listed: Figure 13.Element library after loading the default template After having imported the templates, the model can now be assembled. 25.07.201413 / 31 4.5Principles 4.5.1Elements, Templates In KISSsys, a model is assembled from different elements. These elements are arranged in a tree structure. The following types of elements are available: FolderAnalysis modules for the respective machine element (light blue) Machine elements (grey symbols) Connections (constraint elements in grey) Graphics Tables Theyareavailablefromalibrary,calledthetemplates.Thetemplatesmaybemodifiedbytheuser (recommended for experienced users only). The template is based on the classes. The User or the Administrator has no permission to change the classes. Usually it will not use.

The user can switch between the elements arranged in the tree structure and the templates using the tabs as shown below, or for easier use tabs can be arranged to be seen simultaneously: Figure 14.Model and Templates The model is arranged in the Model - section. 4.5.2Copy, rename, delete User can select how to copy elements from templates to the model. You may drag and drop elements or you can copy and paste elements from the templates to the tree structure using Ctrl+C / Ctrl+V or, with right mouseclick,copy/paste.DeleteelementsbyselectingthemandpressDelorrightmouseclickand Delete element. Renaming an element is performed by right mouse click and selection of Rename. This is the classical method. 4.5.3Insert In this menu are 4 assistants and it is only available from KISSsoft 03-2014. Figure 15.Menu Insert Note: Renaming an element will result in the connections to this element being invalid. Renaming elements is hence not recommended. 25.07.201414 / 31 The menu Insert Parallel shafts assistant is an assistant to build a helical stage gearbox. It will guide the user step by step through the whole model. The tables are not part of this assistant.

As explained in the previous chapter, the Template which is loaded will be used to add elements to the tree structure. With the third assistant Element-Box, the most common elements from the templates will be find in here. Figure 16.Parallel shafts assistant and Elements-Box The user has to define the starting position in the element tree, to add elements from the two assistants to the model. This will happen by clicking the element in the assistant. 4.5.4Naming conventionen Under the menu Extras Settings Elements, the default settings can be changed here for the automatic name settings, when a new element will be add to the model. In this tutorial the default setting will be used. 25.07.201415 / 31 4.6Insert machine elements ThemodellingofthistutorialwillbeusedwiththeParallelshaftsassistant.Allelementswillbeaddtoa group. The element kSysGroup will placed on the root directory (_O.). During the insert procedure the name can be changed e.g. to GB. Figure 17.Add a kSysGroup Menu Insert Parallel shafts assistant 1.Root directory will be chosen automatically 2.Add kSysGroup 3.Rename the group with GB 4.In the element tree the new group will be shown 5.In the schematic the new group will be illustrated as a box The Parallel shafts assistant will guide the user step by step to the finished model. Now add a new shaft to the group GB. Additionally under the group the new shaft will be shown. This element is necessary for the gears, bearings and couplings. The use of this assistant is to finish shaft by shaft. The configuration for the shaft looks as follow.

In KISSsys this element represent by kSysSpeedOrForce. This element will be placed at the same level as the group GB. The group itself is the gearbox,whichisconnectedforexamplewithamotorandgenerator.Inthistutorialtheinputspeedand output torque are given. One level up, before adding the external elements. Figure 21.Main Menu Figure 22.Add In- and Output elements 25.07.201419 / 31 Input element: 1.Add kSysSpeedOrForce element rename to Input 2.The Input element will be connected with the coupling from the shaft1 (^.GB.shaft1.coupling1) 3.Speed constraint yes.

The torque is -1000 Nm4.Power/Torque input Torque with sign. The idea of this model is, to define it for several scenarios. This is the reason why it is not defined as Torque driven. With this possibility it will be easy to define the power flow with the sign of the torque. 5.OK 6.Close the assistant The model is now finished without tables. 25.07.201420 / 31 Figure 24.Two stage helical gearbox before and after the kinematic calculation Toseethepowerflowinyourschematicrunthekinematiccalculation.Inthisstepyoucancheckthe functionality of the power flow. 4.9Calculation definition Thecalculationshallbestartedalwayswiththegearcalculationfirst.Thecalculateddatafromthegear geometrywillbeforwardedtotheshaftcalculation.Asdefined inthetask,thismodelwillbeused forthe gearbox rating and recalculation. The gear and shaft data will be kept simple in this tutorial. The modification will be done by the user, which has usually no influence on the model.4.9.1Gear pair definition The gear data will be defined with the rough sizing in KISSsys. In every kSoftHelicalGearPair is an additional function GearSizing available. With this function KISSsys will generate a gear pair by defining the ratio, the pressure angle and helix angle. 25.07.201421 / 31 Figure 25.Rough sizing for helical gear pair The data for the first stage are. -i = 5 - = 20 - = 15 Repeat these steps also for the second stage. The data for the second stage are. -i = 4 - = 15 - = 0 Modification for the gears will be done in the KISSsoft interface. This steps give the user the first dimension about the gears. 25.07.201422 / 31 4.9.2Definition of the shaft geometry With double click on the KISSsoft shaft analysis modules Shaft1_calc, Shaft2_calc and Shaft3_calc the KISSsoftshaftanalysisisstarted.Here,inthegraphicalshafteditor,theshaftcanbemodelledindetail. When opening the shaft editor, no shaft is visible, only the elements positioned on the shafts are present. To keep it simple, a cylindrical element of diameter D=30mm and length 200mm is defined for all three shafts, shown here for the first shaft: Figure 26.Shaft geometry shaft1 The end position and geometry form of the other machine elements, bearings and coupling will be defined later. The shaft can now be detailed in the usual way. You can also adapt the bearings and the couplings accordingtotheshaftdiameter.Itisalsopossibletodefinebearingsinshaftmoduleincludingtheaxial supporting. After definition press Calculate F5 in order to start the shaft analysis. This is necessary to get reaction forces on the bearings which are in turn necessary for the bearing definition/analysis. Repeatthisstepforallothershafts(inthisexampleallshaftshavethesamelengthof200mm,andthe diameter are 30mm, 40mm and 60mm for shaft1, 2 and 3). 4.103D-View and positioningTo show the defined geometry in KISSsys it is essential to add the kSys3DView from the Elments-Box into the root directory. Figure 27.Element-Box System element 25.07.201423 / 31 Double click on the kSys3DView element in the element tree and a new tab of the 3D will be shown. Or use the submenu with the right mouse button and click show to open the graphic tab.All shaft are overlaying each other, because the positioning of the shafts is not yet defined. Figure 28.3DView without positioning 4.10.1 Positioning of the shafts The shafts are still to be positioned with respect to each other. The shaft1 will be set as reference. This is similar to a CAD-System in the assembly. All other elements will take the reference to this shaft. The second shaft should be parallel to the first shaft, the distance being the centre distance of the first gear pair. Shaft 3 should be parallel to shaft 2, and again in the distance of the centre distance of the second gear pair. Positioning procedure is started by right mouse click onshaft1,shaft2 and shaft3, select Dialog: Figure 29.Dialog of shaft The shaft shaft1 will use the functionParallel to Shaft/Group. As alreadymentioned the shaft1 will be fixed in the space. When the shaft shaft1 has to be positioned at a certain position, then this can be defined in the interface mask. In this example it will stays at the current position (0/0/0). Figure 30.Fixing ofshaft1 25.07.201424 / 31 Secondtheintermediateshaftwillbeplacedrelativelytotheinputshaft.Underthedialogthefunction According to gear pair will be chosen: Figure 31.According to gear pair Figure 32.Formula in the positioning dialog Choose the Gear pairs and let the definition according to Formulas.

Figure 42.Condition and formula to calculate efficiency of the system and convert the value to a text 5.2.4Execution of functions In the user interface, functions can be included. In this example, four functions are included: - Function KinematicCalculate the kinematics of the gearbox - Function StrengthExecution of KISSsoft strength analysis - Function GP 1KISSsoft interface for gears of first stage - Function GP 2KISSsoft interface for gears of second stage 25.07.201429 / 31 Figure 43.Defining calculation in UserInterface Functions can also be defined within a field of the user interface (right mouse click, Insert function). A name for the function is to be given and the commands to be executed have to be listed. For the function Kinematic: Figure 44.Function to calculate the kinematics The name of the function Kinematic will be visible in the User Interface, but has no other effect otherwise. _O.System.calcKinematic(); means that in System, the function calcKinematic is executed (empty brackets since no values are handed over to the function), ; to complete the command line kSys_Refresh corresponds to Refresh All, to ensure that the values calculated (the output speed and the input torque) are shown as results in the user interface. Enter the following text:_O.System.calcKinematic(); kSys_Refresh(); For the function Strength Figure 45.Figure 5.2-1 Function to calculate the strength In the first step, the kinematics of the gear is analysed again to ensure that the correct power is used. _O.System.kSoftCalculate(); calls the function kSoftCalculate under System. This command executes all KISSsoft strength analysis. Enter the following text:_O.System.calcKinematic(); _O.System.kSoftCalculate(); kSys_Refresh(); 25.07.201430 / 31 For the function GP 1 and GP 2: The command kSoftInterface opens the corresponding KISSsoft analysis.

Figure 48.3D specific settings 6.2Display of the coupling The couplings may not yet be shown in the 3D view since their width is still zero. Right mouse click on the couplings(Coupling1andCoupling2),Propertiesanddefinevariableb(=width)andd(=diameter). Let the width be 20 mm and the diameter 70 mm for example. After RefreshAll the 3D view looks as follows: Figure 49.Figure 6.2-2 3D-View of the couplings (red) 6.3Definition of the force acting on the output shaft On the output shaft, a force has been introduced. The five components of the force (Fx, Fy, Fz, Mx, Mz) can either be defined in the Properties directly or through the user interface (reference to the variable, as shown above). The force has an effect on the lifetime of the bearings, but not the gears.
