Development and Validation of a Simulation Model of Automotive Suspension System using MSC-ADAMS

The design of a vehicle suspension is a complex and challenging task. The suspension system serves a dual purpose of providing adequate ride comfort and road holding which are two contradicting parameters. The limits for achieving an optimum RC value is governed by the ISO 2631-1 1997. An Experiment was conducted on a quarter car test rig to obtain the ride comfort by varying different parameters. The same dimensions of the test rig were replicated to develop a quarter car simulation model in ADAMS. This paper primarily focuses on developing a validated quarter car model in ADAMS. Validation of the models were carried out by performing the same set of trial as on the quarter car model with experimental set up and on ADMS model. The input parameters considered were sprung and un sprung mass, tyre pressure, speed, spring and damper stiffness. Also, wheel alignment parameters have been considered such as camber and toe. The developed ADAMS model obtained a good correlation with the experimental test rig and hence, the model can be used for further analysis and optimization. (C) 2017 Elsevier Ltd. All rights reserved.
