Abstract The design of a vehicle suspension, which is truly a multi-degree of freedom mechanism, is really challenging. This paper primarily focuses on Kinematics and Dynamic analysis of the system in ADAMS. A specific module of chassis platform is developed to analyze suspension ride comfort on adaptability to different vehicle with ADAMS/Car. The work intention is to make a parametric ADAMS model and then link it to a Knowledge Based Engineering application to facilitate designer to quickly carry out designing iterations in order to reduce development time. The Knowledge Based Engineering software is made using object oriented language called ‘Object Definition Language’ which is developed using VC++ software languages. The module not only carry through parametric modeling of front and rear suspension and other subsystems of chassis quickly and compactly, but also can carry on the analysis and optimization of various factors those have crucial impact on ride comfort. The module offers two test-bend, vehicle virtual simulation test stand and four-post test rig. Finally, the module is applied to analyze two kinds of cars which used chassis platform: front and rear frequency determination, pulse inspiration simulation and Broad simulation. The results show that the chassis platform being adopted by two kinds of cars meet the ride comfort requirements.
