Characterization of the vehicle roll movement with the dynamic chassis simulator

Abstract

Suspension Kinematics and Compliance (K&C) test rigs are one of the most important measuring facilities in the automobile industry, which support chassis engineers for chassis tuning and development as well as vehicle dynamics simulations. The Dynamic Chassis Simulator (DCS) at TU Dresden is a dynamic K&C test rig, appropriate for quasi-static and dynamic suspension K&C analyses. This paper presents the characterization method of the vehicle roll movement by applying relevant measurements on the DCS test rig. Important chassis design parameters in consideration with the roll motion are discussed and testing maneuvers on the DCS test rig to determine the design parameters are also explained. The validity of the characterization process of the roll movement has been proved with the field test data.
