Damping parameters of suspension of passenger vehicle equipped with semi-active dampers with by-pass valve

Abstract

The paper presents results of experimental tests of characteristics of semi-active dampers with by-pass valve and results of calculations evaluating suspension damping ratio taking into consideration also installation ratio and vehicle sprung mass changes. The asymmetry of damper characteristic is also investigated and changes in damper damping coefficients versus damper velocity. The papers also compares these values of passive damper used in this car with tested semi-active damper.
