利用拉格朗日方程,建立了带非独立悬架的汽车多自由度振动系统的运动微分方程.基于现代控制理论,建立了汽车振动系统的状态空间模型,提出了某车型的一套仿真参数值.通过系统模态分析,计算出该车型振动系统的固有频率与主振型.利用仿真分析与实车的试验方法分析了状态空间模型误差,验证了所提出的模型及其参数值的有效性.研究结果表明,建立的汽车振动系统状态空间模型及析取的参数值是有效的.

The differential of equation of motion was derived by using Lagrange equation for vehicle multi-DOF vibration system with non-single suspension system. The state space model for vehicle vibration system could be constructed by applying modern control theory. The parametric values are presented. By analyzing mode of the dynamic system, inherent characteristics of the vehicle system were calculated. By contrasting simulation data of state space model with testing data of the mini-car, the validity of the model and its parametric values was researched. It is indica...
