DEPENDENCY STUDY OF BODY DISPLACEMENT AND CONTROL AMPLITUDE OF VIBRATION PROTECTION OBJECT OSCILLATIONS OF WHEELED VEHICLES

Abstract

PURPOSE. The article studies the dependence of the change in the maximum value of body displacement and the maximum value of the control amplitude of solid body protection object oscillations. METHODS. The efficiency of the two-stage method of parameter synthesis is analyzed. These parameters ensure specified requirements to the quality of vibration isolation taking into account a mathematical design model of the system of vibration protection from a given kinematic impact caused by harmonic and polyharmonic oscillations of the base. RESULTS AND THEIR DISCUSSION. It is shown that the problem of synthesis of optimal structures of the vibration isolation system can be reduced to the problem of parametric optimization. We treat the problem of parametric optimization of the vibration protection system as a problem of determining the optimal parameters of the object vibration isolation system under the selected (or given) structure and available complete information about the object and perturbations affecting it. CONCLUSIONS. It is determined that if vibration protection system is optimal the growth of the value α causes the increase in maximum displacement whereas the maximum value of the control function decreases. Therefore, choosing the weighting factor α we can achieve simultaneous fulfillment of the quality requirements for vibration protection and limit overall dimensions.
