The impact of primary suspension stiffness of 2-axle bogie of MKIII passenger car on its dynamical behaviour

摘要

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