SIMULATION-DRIVEN-DESIGN AND PROCESSAUTOMATIZATION ON THE 3DX PLATFORM

3DEXPERIENCE Conference, Darmstadt, 21.11.2019

Daniel Vallicotti

SIMULATION-DRIVEN-DESIGN AND PROCESS AUTOMATIZATIONSCENARIO

I. In order to accelerate the development cycle design engineers are to be supported by simulations when designing new machine superstructures.

II. The simulation must run as a "black-box" in the background and no additional know-how on the part of the designers should be required.

III. Geometry changes should easily be incorporated and should not lead to large additional expenditure.

IV. Template-based, automated workflows should relieve the simulation experts so that they have more time for method development.

SIMULATION-DRIVEN-DESIGN AND PROCESS AUTOMATIZATIONSCENARIO

For different tools, the load-related deviation of the tool tip must lie within a certain tolerance (requirement profile).

Key parameters are the geometry of the tool, travel paths of the tip, sheet thicknesses of the superstructure and the position of the tool (extreme positions).

The effects of these design parameters are to be checked directly by the designer during the development process.

CATIA/SIMULIA – MODEL PREPARATIONPARAMETRIC MODELING: VERIFICATION


CATIA/SIMULIA – MODEL PREPARATIONPARAMETRIC MODELING IN SIMULIA


Switching betweenthe CAD modules formodel preparationand the SIMULIA modeling is done bya few clicks. The GUI doesn‘tchange drasticallyand every definitionis accessible via themodel tree.



The model definitionis placed in thescenario tree.

Parametrization ofthe loading is donevia a loading scalefactor on a unityload.



In the post-processing, sensors are used tomake the output offield quantitiesaccessible in theProcess Composer.

CATIA/SIMULIA – MODEL PREPARATIONREVISIONING OF GEOMETRY


The machine head caneasily be replaced, e.g. by revisioning. The model definitionsare automaticallyadapted and noredefinition is needed.

This enablesautomated testing ofdifferent machinetypes.

SIMULIA – PROCESS COMPOSERSETUP OF A SIMPLE DOE STUDY


SIMULIA – PROCESS COMPOSERSETUP OF A SIMPLE DOE STUDY

Choose the variables for the DOE study and specify their range, depending on the chosen DOE technique (values, %, etc.).

Here, the tool positioning is preconfigured to cover the extreme values. The load factor and sheet thicknesses are input variables of the designer.

To examine the influence of the mesh density, three different mesh sizes are checked.

Factors

The objective function is computed in dependence of the chosen output parameters.

The reponse variables can be minimized, maximized or approaching a target value.

Multiple output variables can contribute to the objective function. A normalization of the values is recommended to not over-/undervalue a certain argument.

Create a user interface by using the provided components.



The variables of the DOE study and further properties of the simulation are directly available and can be linked to the buttons/sliders/inputs of the user interface.



Additional parameters of the DOE. Need to be entered by the template user.

Predefined parameters of the DOE (read-only). Cannot be accessed by the template user.

Web-based app to start a simulation/study while using the interface provided by the method developer. The simulation knowledge is hidden behind the template.



The designer can directly study the influence of different parameters on the overall systems response and is therefore able to propose feasible designs for further investigations.

The simulations are executed via the web application. No local installation is required for the designer.

Color-coding shows the feasibility of the designs.



Different departements that are involved in the project can vote for their favorite design based on personal criteria, such as availability of materials, cost, longevity, etc.
