Abstract
BACKGROUND: Optimization of the suspension system, its operating parameters, as well as active adjustment depending on the ground surface can significantly affect the fatigue resistance, improve comfort during operation ensuring smoothness of ride, reduce the pressure on ground, increase the overall energy efficiency of the mobile energy unit. Therefore, in this approach, there are theoretical calculations to find the optimal range for control of the simulation bench to study the parameters of the active suspension system. AIM: Development of optimal operating conditions of the control system of the simulation bench, minimization of vibrations and oscillations, prediction of the system behavior in different conditions and modes of operation. METHODS: The development of optimal control is based on the analysis of scientific works, including publications, scientific papers and other sources of information on the approaches to the development of optimal control of the performing device in the active suspension system for the most effective damping of vibrations arising from road unevenness. The method of theoretical calculation of three-factor experiment was used, the main dependencies were obtained. RESULTS: The obtained equations have a high level of significance. Graphical representation makes it possible to make a qualitative assessment of the accuracy of the obtained equations. The equations make it possible to control the parameters of the adaptive suspension system with several criteria. Each criterion included in the equation influences on the function itself. In order to develop the optimal control, the obtained equations are applied in the software development. CONCLUSION: The practical significance lies in the developed equations for the software concerning the optimal control of the simulation bench, the relationship between independent variables such as velocity, microprofile height and suspension stiffness has been established.
