摘　　要：从空气弹簧非线性特性人手对汽车空气弹簧悬架系统进行分析，运用Matlab／Simulink软件进行空气弹簧非线性曲线拟合和悬架系统的仿真计算，在此基础上进行了实际随机输入路面上的汽车平顺性试验，并对试验仪器及过程进行了详细描述。通过对试验结果与仿真数据的比较，证实了理论分析的正确性和仿真的准确性。Based on nonlinear characteristics of air suspension, the paper makes analysis of automobile air suspension, and by using Matlab/Simulink software, it combines air suspension nonlinear curves and makes emulation calculation of the suspension system, based on which riding smoothness test data are input at random. The paper also gives detailed descriptions of the testing apparatus and testing process. By comparing the testing results with the emulation data, it certifies that the theoretic analysis is correct and emulation is accurate.
