起重机载荷谱是进行起重机金属结构疲劳剩余寿命估算和可靠性分析的基础性数据。阐述了起重机载荷一时间历程数据获取和统计分析的基本方法以及起重机载荷谱的编制方法,综述了国内外起重机载荷谱的研究现状和成果,提出了起重机载荷谱研究的展望。
The crane load spectrums are the basic data for evaluation of fatigue residual life and reliability analysis of crane metal structure. This paper describes the basic methods of data acquisition and statistical analysis of the load-time history as well as preparation method of the load spectrum for the crane. Then the research status and achievement of the domestic and international crane load spectrum is summarized. Finally, the research prospect of crane load spectrum is put forward.
