摘要
为了研究汽车振动响应的幅频特性,利用拉格朗日方程建立了1/4车辆几何模型,并利用Simulink对车辆振动响应幅频特性进行了仿真.结果表明:减振器阻尼系数的适当增加可以有效降低共振时车轮与路面之间的动载;而悬架刚度的增加会使车辆行驶平顺性变差.分析结果对提高车辆行驶平顺性和安全性具有一定的参考价值.
In order to research amplitude-frequency characteristic of vehicle vibration response,using the Lagrange equation to establish quarter vehical geometry model and design the simulation program in Simulink according to the above mathematical model.The results indicate that the proper increasing of shock absorber damping can effectively reduce the dynamic load between the wheels and pavement.But,the increasing of Suspension stiffness makes the ride comfort go bad.The conclusion of this paper can provide some reference value with which can improve the vehicle smooth and safety.
