基于MATLAB的轿车悬架系统模型简化

摘要

悬架系统是汽车系统中非常重要的一部分，它在汽车行驶平顺性和操作稳定性方面起着至关重要的作用。通过对轿车悬架模型的简化，得出独立悬架传递函数。为验证传递函数的正确性以及模型简化的合理性，在参数取值范围内，任意选取一组参数值，应用MATLAB中M 函数进行测试。测试结果证明，该传递函数正确，该模型合理，可作为今后研制、开发轿车悬架系统的一种测试、检验模型。%Suspension system is a very important part of the vehicle system ,it greatly affects the ride performance and operation stability of vehicles .In this paper ,the independent suspension transfer function for a car is set up after the car suspension model is simplified .To verify the correctness of the transfer function and the rationality of the simplified model ,a set of parameter values is freely chosen within the scope of the parameter selection ,and the simulation test is carried out by use of M function of MATLAB . Test results show that the transfer function is correct and the model is reasonable .This model can be used as a testing and inspection model in the development of car suspension system in the future .
