Comparison of suspension rig measurements with computer simulation

A McPherson strut front suspension system has formed the basis of a study comparing actual rig measurements with a computer simulation. The study is based on a Peugeot 605 suspension located at Coventry University. The software used, ADAMS (Automatic Dynamic Analysis of Mechanical Systems) (R. Ryan, 1993) is well established within the automotive industry. The paper describes the experimental methods used to measure camber angle change, caster angle change, steer change, track change, and wheel rate. These measurements were taken when the rig was jacked up and down from a static condition. The methods used to model and obtain the same results in ADAMS are also discussed. The results obtained from both methods are compared. The paper concludes by discussing future applications of the ADAMS model for more sophisticated analyses, including the simulation of anti-lock braking systems
