摘要
本文把从北京市、黑龙江省等地道路的实测资料中获得的路面不平整度的功率谱密度函数作为输入,把车辆简化成两个自由度体系,利用随机振动的方法分析了行驶车辆作用于路面的随机动压力.
In this paper, in the light of the field data of Beijing city and Heilong jiang province, the power spectral density functions of highway pavement roughnes are input and the vehicle is considered as two degrees of freedom system for invest gating the random dynamic pressure of moving truck on the pavement by means ?? random vibration method.
