摘要
以四峰谷值雨流计数法为基础,介绍了雨流计数的快速实现方法。该方法在计数前需要对载荷时间历程进行非峰谷值点的去除和重调整处理。计数过程中将需保留数据单独存放,计数判定点的选取遵循单向选取、循环进行的原则,直至将载荷时间历程全部计数为一系列的全循环。最后以一工程应用实例证明了该方法有着很高的效率。
Based on four points counting method, the rapid realization method of rain-flow counting was introduced. By this method, points in the load spectrum should be discarded before counting except peak or valley points, and the load spectrum should be reconstructed. The reserved-data were stored separately in the counting process. The selection of the points for the counting obeyed the unidirectional principle, and the process repeated until all the points in the load spectrum have been counted as a series of cycles. Finally, the high efficiency of the method was proved by an example on engineering.
