摘　　要：首先建立了货车整车动力学模型,针对该模型给出了计算频域内的四轮随机输入下加速度功率谱密度响应的算法和程序流程,并在LabVIEW中利用其提供的线性代数矩阵节点编写了计算程序。以CA-141货车为例,利用LabVIEW编写的程序计算车身质心垂向加速度功率谱密度,并与实测结果进行了比较。First a dynamic model of the truck is constructed. According to the model the arithmetic and program proceeding of computing acceleration power spectral density responding to four rolls random input is offered, and using linear algebra matrix nodes in LabVIEW the computing program is written. Taking CA-141 truck as an example, the vertical acceleration power spectral density of the truck body＇s gravity center is computed using the program written by LabVIEW.
