| 摘 要： | 阐述了基于随机有限元的车辆行动部分可靠性原理及基本过程,将结构件的弹性模量、泊松比和几何尺寸等因素定义为随机场,并对其进行离散,同时分析了车辆行驶的典型路面的路面谱,利用随机有限元求解在不同的路面状况下车辆行动零部件的受力情况,得到了零部件危险点应力的随机分布和不同路面状况下疲劳可靠性,并对相关的实例进行分析。

| Abstract: | The basic process of stochastic finite element method analysis in reliability of vehicles running gear is given.Through the Young's modulus,Poisson's ratio and geometry dimension of structural components are considered as stochastic fields and the fields are separated as stochastic variables.By analyzing the road surface spectrum of the typical pavement,the value of force and the stress of the vehicles running gear parts in different pavement are solved;random distribution in fatigue failure zone is compute... |
