Automatization of calculation of dynamic characteristics of the car suspension system

Abstract

Abstract The article deals with the questions of finding the parameters of generalized coordinates for plane linear dynamic systems of any structure with degrees of freedom, used in the study of suspension systems. The appropriateness of separation of a number of subsystems for each of which potential energy and dissipative function are calculated by the same type equations is shown. As an example, the differential equations describing in the general case the linear movements of the masses of the dynamic system are given. It is shown that in order to find the parameters of generalized coordinates of a flat linear dynamic system with degrees of freedom at the kinematic harmonic disturbance determined by the structure of the road surface, a solution of the system of linear algebraic equations is required.
