Abstract： In order to analyze the adaptation of an automobile chassis platform in handling stability and ride comfort when assembled in different car models， VC++ and ADAMS were used to develop a specific simulation module for suspension performance analysis of the chassis platform， which could not only create the parametric  modeling of the front and rear suspension， the other subsystems and the whole vehicle quickly ，but also accomplish the analysis and optimization of handling stability and ride comfort. By adopting this module， kinematic simulation analysis and vehicle simulation model for the front and rear suspension of this chassis platform when assembled in two different cars models named A1， A2 were carried out， then steering pulse simulation analysis which can reflect handling stability， score evaluation and analysis of ride comfort in random road were proceeded according to the national standards. The results show that this simulation module has superior application value in engineering and the two different car models equipped with this chassis platform have better handling stability and ride comfort.
