General Conclusions and Recommendations

1. The analysis of the use of oil and air pipe-lines’ piston pumps and compressorshinged mechanisms has revealed the necessity of multi-disciplinary study ofthese machines and mechanisms and their maintenance to ensure their relia-bility and durability.

2. Scientific articles and researches on crank-piston mechanisms reveal variousfactors that act on piston machines and mechanism (external forces, reactionforces, friction, clearances, wear, impacts in kinematic pairs, deformation oflinks); that kinematic and dynamic study represents a significant problem.

3. The general problems of cranks-piston mechanism dynamics with three clear-ances in kinematic pairs as well as the basic and additional motions of mech-anism were determined. From the results of the survey, 44 differential equationsare obtained, from which 36 describes the additional motion of mechanism(Contact-Contact, Contact-Break, Break-Contact, Break-Break), and 8, thebasic motion of mechanism. It is recommended to carry out a dynamic study ofcranks-piston mechanism with clearances in two rotational kinematic pairstaking into account additional and basic motions.

4. For a full-fledge dynamic research of crank-piston mechanisms with clearancesconsidering their additional and basic motions and to do a comparative analysisof the obtained results, it is recommended first of all, to carry out research of anideal mechanism. The study of additional and basic motions of cranks-pistonmechanism with clearances led to the identification of four types of motion,accompanied by a basic motion. For all the kinds of motion, differentialequations of the kinetic energy and motion are obtained. In kinematic pairs,reaction and friction forces are defined. To obtain differential equations, tran-sition from one type of additional motion to another should be done by keepinginitial conditions that would be incorporated into additional motionsub-programs and would be active in force mechanisms and linear contourbreak or closure.

5. From the study of basic mechanism and additional motions of mechanism, thereal law of motion is revealed, true values of forces have been investigated.Comparative analysis has led to the determination of the real law of crank

motion and optimal values of desired parameters that contribute to reliable anddurable operation of piston machines.

6. The influence of operational characteristics—friction, wear—of cranks-pistonmechanism’s kinematic pairs have been studied and investigated. The study offriction has shown that instability of the tribotechnical characteristics of pairedelements leads to a gradual loss of workability of item, change in separate links’strength and stiffness, which is directly related to wear. In the rotationalkinematic pairs from the study of friction, it is possible to know the causes offriction wear problem. It is revealed that crank-piston mechanism paired units’normal operation, friction surfaces wear intensively, durability depends on thesurface state, their layers’ mechanical properties, microgeometry, instability oftribotechnical characteristics, operating conditions, etc.

7. The investigations have revealed that the main reasons of cranks-pistonmechanisms and piston machines (friction, wear, jamming, etc.) failures arephysical and chemical properties of the materials(metals stiffness), loads,kinematics and thermodynamics, lubrication, environment. It is recommendedto jointly investigate these interconnected processes that require the develop-ment of very complex calculation methods. This requires joint actions ofphysicists, chemists, mathematicians, thermodynamics specialists, highlyqualified engineers.

8. From the investigation of piston machines and their mechanisms, it is deter-mined that the issue of crack formation should be considered based on friction,wear, stiffness, metals structure and so on. In the paired elements, phenomenaof contact, breaks, impacts that cause the increase of forces in joints, vibrationof mechanism, oscillations and crack formation must be taken into account. It isrecommended that to avoid crack formation, it is necessary to investigate pistonmachines and mechanisms taking into account elasticity of links and thevibrations that will ensure their reliability and durability.

9. From the research of cranks-reciprocating mechanisms and machines operatingcharacteristics (friction, clearance, wear, impact), used for solving simultaneousdifferential equations. It is seen that clearances in kinematic pairs dramaticallyaffect the values of reaction and friction forces, which cause sharp changes inthe piston and coupler velocity and acceleration laws. It is shown that increasein clearances increases machines and mechanisms dynamic stresses, which leadto a sharp change in the angular velocity of crank and vibration of the machine.It is recommended to manufacture the pair’s elements from wear resistancematerials and dimensions of clearance should be selected optimally, thusensuring the reliability and durability of machines and mechanisms.

10. From the investigation of piston pumps’ mechanisms taking into account theimpact of the operational characteristics, it is revealed that systematic repetitionof this phenomenon would cause premature wear of pair’s elements and failureof machine. Using the classic form equations in researches considering twophases of impact, it is seen that the ratio of loading and unloading normalimpulses values of the restoration coefficient for different values lead to changesin the reaction forces. Increased restoration coefficient decreases the maximum

value of the reaction force and opens a number of kinematic chains. Due to therotation of crank rotation on same angle, there is declining difference betweenthe ideal and real mechanism reaction forces values. The mechanism of themaximum value of reaction force changes in kinematic pair, depending on thesize of the clearance. In heavily loaded piston pumps mechanism, optimalvalues of clearance in this mechanism will be reliable and durable.

11. In a dynamic research of crank-piston mechanism, the following operatingcharacteristics were taken into consideration: friction, clearance, friction andclearance, friction, clearance and wear, clearances and impacts in clearancestolerance zone, ratio between clearances and deformations of links; they rep-resent the reference materials. The kinematic parameters of ideal mechanismand reaction forces caused by external forces are defined. The MATLAB usedfor solving simultaneous differential equations provides automated transitionfrom one mode of dynamic research to another. From the solution of simul-taneous equations, real characteristic parameters are calculated; their influenceson pair’s elements motion character, change of reaction forces in kinematicpairs and law of crank motion are revealed.

12. The comparative analysis of ideal and real crank-piston mechanism kinematicand dynamic parameters revealed that ideal and real parameters are sharplydifferent, leading to kinematic as well as dynamic changes in mechanism. Thereal law of drive link motion sharply differs from that of ideal. There is vio-lation in crank law of motion and its oscillations. For maintaining constancy incrank angular velocity, it is necessary in kinematic pairs of mechanism tooptimally select the value of clearance that provides reliable and durableoperation of mechanism.

13. By increasing restoration coefficient, the maximal values of reaction force aredecreased; clearance values defined ways of clearances selection in kinematicpairs of mechanism that provides reliable and durable operation of crank-pistonmechanism as well as piston machines.In the execution of technological processes by crank-piston mechanism, atten-tion should be given to wear in pair’s elements of kinematic pairs. Increasedstress in piston machines and mechanisms causes deformation of links, crackformation and sharp difference in the constant value of crank angular velocity.This indicates the necessity of maintaining geometrical dimensions of techno-logical clearances in kinematic pairs of mechanism and manufacturing ofelements of kinematic pairs from more wear resistance materials that providesreliable and durable operation of crank-piston mechanism.

14. Significant result is obtained from the dynamic research of pumps and com-pressors of crank-piston mechanism considering clearances in kinematic pairsand elasticity of links. Without compilation of partial derivatives differentialequations from successive approximation methods defined deformation ofmechanism’s coupler with distributed mass. From the reduced stiffness coef-ficient of mechanism and for two-mass model (motor, mechanism), simulta-neous differential equations are obtained. To study the crank-piston mechanism,

General Conclusions and Recommendations 221

the dynamic model is considered as oscillation system with one DOF and waysof resonance origination and its definition are shown, as well as influence ofclearances and friction forces on operation of mechanism. The dynamic pro-cesses in crank-piston mechanism with elastic links are studied firstly for ideal,and then for real mechanisms. Runge-Kutta methods and computational engi-neering are done to study mechanism with clearances; and based on the couplerstiffness and rpm of crank, the elastic deformations are determined. Withelasticity of links and selection of relevant stiffness, it is possible to producesuch a mechanism and machine whose structural elements will be reliable foroperation. Based on comparative analysis, ideal and real parameters are used todefine reliability and durability of the applied pumps and compressors ofcranks-piston mechanisms.

15. Using dynamic research of crank-piston mechanism with clearances in kine-matic pairs and elasticity of links with concentrated masses, it is possible toconduct comparative analysis for obtaining mechanisms with distributed massresults.

16. This work studied the kinematic and dynamic errors of crank-piston mecha-nism, their causes and ways of avoiding them, in order to ensure their reliabilityand durability.
