THE IMPACT OF PRIMARY SUSPENSION STIFFNESS OF 2-AXLE BOGIE OF MKIII PASSENGER CAR ON ITS DYNAMICAL BEHAVIOUR

Abstract

This article presents results of the study on the impact of stiffness in vehicle primary suspension for lateral direction kzy and longitudinal direction kzx. The study was carried out for 2-axle bogie of MKIII passenger car. The problem was solved by numerical tests performed with the simulation software for dynamics of vehicle-track system. Performed study consisted in varying both stiffness types through change of their values from 0.001 to 1000 times as compared to nominal value.
