摘要
根据材料特性和雨流计数法原理对四峰－谷值雨流计数法作了改进，用新的二峰－谷值计数法代替了四峰－谷值计数法，保持了载荷循环发生的次序，完整记录了整个历程的损伤，使得对机械设备的疲劳分析更为精确。
A method for modified rainflow counting that is based on the cyclic material behaviour is presented. By that, “ four points counting ” has taken the place of the new “ two points counting ” that can make fatigue analysis more accurate and maintain the loading sequence.
