Abstract
A suspension system can be modeled using a mechanism analysis program to represent a real hardware system. Once a good computer model is obtained, a parametric study for a specific suspension design factor, like a toe angle, can be done to obtain sensitivity information. Using this information, several important design parameters for a specific design factor can be identified. Using this information, a systematic experimental plan can be obtained for a specific design goal using an experimental orthogonal table. With this experimental results, a function which represent the relationship between the design function and parameters can be obtained using a response surface analysis method. This function is used to obtain optimal design values of the design parameters for a given design goal.
