| 摘 要： | 本文以ＣＡ１０９１货车振动系统进行分析和简化，将ＣＡ１０９１货车简化成八自由三维空间质弹系统模型，以四轮的路面随机激励作为系统的输入，用计算机模拟车身和司机座椅的频率响应，用Ｃ语言编写了计算程序，并计算和绘制出货车车身及司机座椅垂直加速度功率谱曲线。

| Abstract: | The model for CA1091 truck vibration system is analysed in the paper with the truck simplified into a 8_degrees of freedom 3_dimension mass spring system model.Taking the spectrum of road excitation as the imput of 4_wheels,the response of the truck systern is discussed in frequency domain.The algorithm is compiled with Turb.c.programme.The power spectrum graphs of truck_body and driver's seat are put forward for visualisation. |
