In order to make up for the deficiencies of the rain-flow counting method using four peak-valley values, an equivalent load cycle rain-flow counting method for aeroengine life monitoring is presented.
针对航空发动机寿命监控,为弥补四峰-谷值雨流计数法的不足,提出了等效载荷循环雨流计数法。
It counts load cycles by time, registers all loading course without altering the magnitude and sequence.
该计数法按时间顺序计算载荷循环,能完整记录全部载荷历程而不改变其大小和顺序,弥补了常用雨流计数法的缺陷;而且该算法精确度高,抗随机噪声干扰能力强,使得载荷谱分析更加准确。
