Design and Simulation of the Suspension System of Chassis Platform Based on Handling Stability 2010-01-0723

Chassis platform is usually supplied for several types of cars which have their individual requirement for handling stability and ride comfort. Therefore the stiffness, damping and the dimension of the guide mechanism of the suspension have to be adjusted to meet the different performance requirements of different styles of cars. In this paper a module exclusively used for handling stability analysis of chassis platform is developed based on ADAMS/Car. With this module chassis engineers can easily adjust the parameters of suspension such as stiffness, damping and locations of hard points to match the front and rear suspension suitably and then predict and optimize the performance of the suspension system. Therefore different types of cars that using chassis platform can fulfill their own handling stability and ride comfort requirements.
By using the module, parameterized models of the front, rear suspension and the chassis platform were built in this paper, and the kinematic simulation of the suspensions were carried out to analyze their kinematic performance. Then two cars of different type which use the chassis platform were taken as an example to do the cornering simulation and evaluation according to the Chinese National Standard to verify the good applicability of the module for the analysis of suspension kinematic performance and chassis platform handling stability.
