| 摘 要： | 通过对四轮车辆的动力学分析,建立了八自由度车辆的力学模型,计算得到车辆四点随机激励的八自由度耦合振动方程,并用分块矩阵的方法推得车辆振动系统的传递函数,其结果对进一步研究车辆的频率特性、振动强度等问题具有重要的参考价值．

| Abstract: | Based on the dynamic analysis of four-wheel vehicle,the mechanical model of eight freedom vehicle was established,coupled vibration equation for the vehicle of four point random excitation was got according to the calculation,and transfer function of vehicle vibration system was also got by the method of dividing a matrix to blocks. The results had important reference value for further research on the frequency characteristic,the vibration strength of the vehicle, etc. |
