| Abstract: | Air suspension is used in many luxury coaches in order to improve ride comfortable.In this paper a multi-body dynamic coach model is build in ADAMS to analyze the nonlinear spring and damper in suspension system,and presents an interpolation fitting method suitable for ADAMS solvers to optimize these nonlinear variables.Sensitive analysis is also used to find out the key parts to the overall ride comfortable performace. |
