摘要：建立了二自由度1/4汽车悬架物理模型,针对该模型建立了振动微分方程和传递函数。使用MATLAB/simulink模块绘制了模型的Nyquist图和Bode图,分析了模型的动态特性。对汽车行驶过程中的振动原因做了分析。运用ADAMS软件分析了悬架的固有特性,得到了悬架对确定输入和随机输入的响应结果。得出悬架的各种参数、路面等级和汽车行驶速度对汽车行驶平顺性的影响。
A vibration model of 1/4 car body with 2 degrees of freedom was created in this paper. The physical model included differential equations and transfer functions. The Nyquist and Bode figures were drawn by the MATLAB software, and the dynamic performance of physic model was analyzed. The reasons of vibration of the automobile were analyzed too. The emulation model of suspension system was created by ADAMS software. The internal characteristics of suspension system were studied and response of suspension under specified input and stochastic input was analyzed. The relationship between vehicle riding stability and parameters of suspension system was studied, and the relationship between vehicle riding stability and velocity was proposed.
