雨流计数法及在车辆疲劳损伤分析中的应用综述

Review of the Rain Flow Count Method and Its Application in Analysis of Vehicle Fatigue Damage

为了更准确地对车辆疲劳损伤中的随机载荷进行统计分析,雨流计数法成为研究的热点方法。首先,介绍了雨流计数法的理论基础以及程序实现流程,然后针对该方法在诸多国内外期刊中发表的论文进行综述分析,主要包括两个方面:基础理论的深入探讨和在车辆零部件疲劳损伤中的应用。在以后的车辆零部件疲劳损伤研究中,该方法将继续被研究和应用,为更多地研究者方便地使用。

In order to statistic accurately the random load in fatigue damage of the vehicle, the rain flow count method is the heat method. Firstly, the theory basic and the flow of program realization of the rain flow count method were introduced. Then, the papers of applying the method published in many domestic external periodical were reviewed, two aspects were included： the deep discussion of basic theory and the application in fatigue damage of the vehicle parts. In the later study in fatigue damage of vehicle parts, the method will continue to be researched and applied, to be used conveniently for users.
