摘要:In order to improve vehicle ride comfort and reduce the damage to road by tyre dynamic load, a new approach is addressed for designing vehicle suspension systems based on the scheme of multi-objective programming. A four-degrees-of-freedom linear model is used to describe the dynamic behavior of vehicles running on randomly profiled roads. The road irregularity is regarded as a Gaussian random process. The random dynamic responses of vehicle suspension systems are solved by the pseudo excitation method. And the Kriging model is used to build the approximate mapping relationship between the design variables and the responses. The optimal solutions are derived by means of the method of centers for structural optimization with multiple objectives. Numerical examples are given, and compared with other optimization methods.
