摘要
应用蒙特卡罗方法产生伪随机数来进行疲劳载荷的计算机模拟，并基于雨流法的基本原理，对“三峰谷计数法则”作了改进，提出了一种能与载荷信号的发生同步进行的统计计数的计算机算法，这使得结构疲劳寿命的估算与疲劳载荷谱的产生的同步实现成为可能。
This paper discusses the generating and testing techdques of some pseudo---randomnumbers which are used to simulate the fatigue loads with the application of Monte Carlomethod.On the basis of rainflow counting,a computer algorithm is derived from“three一extreme counting rule”。The new algorithm vvill enable the prediction of fatigue life of engi-neering structures to be performed parallel to the simulation of random fatigue load。
