Angular Oscillations of Nonlinear Systems in Spring Suspension of Rolling Stock

https://doi.org/10.46973/1818-5509_2025_2_113

Abstract

In the course of the study, the effect of the restoring moment on the nature of angular oscillations of various systems was studied. It is established that the dependence of the restoring moment on the generalized coordinate (angle of rotation) can be both linear and nonlinear, depending on the use of various elastic bonds. The study of the properties of the restoring moment, which determines the force that returns the object to its original position, opens up the possibility of obtaining the desired regressive-progressive characteristic of objects with elastic bonds, which determines the damping process of the system.
