摘要
本文把路面不平随机过程分解成一个由奇异过程所表示的路面起伏及一个由正则过程所表示的路表不平两个随机过程,并进一步讨论了这两个随机过程的概率特性;以几种典型的、前人的实测结果及作者的实测结果说明了这种分解是合理的。用这种方法建立起的路面不平概率模型深刻地揭示了路面不平的概率特性,对车辆系统动力学研究是非常有用的。
The stochastic process of the road irregularities was decomposed into two processes, one is the process of the road fluctuating represented by a singular process, the other is the process of the road surface irregularities represented by a regular process. Further, the behaviours of the processes were discussed and the reasonableness of the decomposition was verified by using the typical results of a number of measurements made by the former researchers and the author. This probabilistic model of road irregularities established by this method reveal profoundly the probabilistic characteristics of road irregularities and it is very useful to the study of vehicle system dynamics.
