起重机金属结构疲劳载荷时间历程的采集分析

The Picking and Analysis of Farigue Loading Chart for Crane's Structure

通过对几种常见起重机金属结构疲劳载荷时间历程采集方法的分析，提出了采样点的确定原则，并针对不同类型的起重机提出了疲劳载荷时间历程的常规采样点。为保证采样峰值的精度，给出了采样频率的确定方法，最后介绍了“四峰谷计数法”的具体实现过程。

This paper provided the principle of selecting pick-point and gave the usual pick-points in some kinds of crane.In order to assure the accurately peak value,the method of selecting pick-frequence will also be given in this paper In last,the method of four-peak counter will be discussed.
