对桥式起重机金属结构进行应力谱试验，开发了基于全封闭计数模型四峰谷计数原则的雨流计数法程序。然后进行预数据处理、数据处理获得应力谱，并以一台75/30 t的桥式起重机为例，进行现场测试记录，用上述方法获得5d的实际工作循环应力-时间历程。

The stress spectrum test is performed for metal structure of the bridge crane,with the rain-flow counting method developed based on totally enclosed counting model 4 peak-valley counting principle.Then the data pre-processing and data processing are performed to work out the stress spectrum.A 75/30t bridge crane is taken as an example for site test record in order to get the 5 day actual work cyclic stress-time history.
