摘　　要：在进行汽车悬架系统建模时,把减振器建立成线性与非线性两种模型,从而建立相应的两种悬架模型,并运用平均加速度法对这两种模型进行推导求解。在求解过程中运用Matlab中的S-函数构建仿真模块。仿真与试验数据的对比结果表明,选用合适的非线性减振器模型比采用线性模型更符合实际,更利于对汽车平顺性的研究。The shock absorber is dealed with a linear or a non-linear one, and the two corresponding suspension system models are established. The average acceleration method is used to solve these two suspension system models. During the solution process, S-fuiaetion is used to construct simulation model. Compared with the test date,the result indicates that an appropriate nonlinear absorber model is more practical than a linear one, and it is more beneficial to the research of vehicle ride comfort.
