摘　　要：汽车最早应用的是被动悬架,悬架是汽车行驶系的重要组成部分。目前被动悬架应用广泛,通过计算机建模,并建立微分方程,利用现代控制理论的知识,建立二自由度悬架模型的仿真模拟图。分析了悬架在随机输入情况下的悬架动行程、轮胎动位移。仿真出频率函数响应结果曲线。在计算机的模拟与仿真下,对被动悬架有了更深的了解,为进一步工程研究提供了基础。Automobile manufacture first adopted the passive suspension.The suspension is important part of running system of vehicle.The passive suspension is widely used at present.Through computer modeling and establishing differential equation,the simulation diagram of 2-DOF suspension model is established by using the knowledge of modern control theory.The dynamic displacement of suspension and dynamic travel of tire with random input is analyzed in the article.The response curve of frequency function is simulated.Under the computer simulation,we have a deeper understanding of the passive suspension,which provides a foundation for further engineering research.
