发布时间：2018-11-13 19:23
【摘要】：为探明在役海洋平台的动力学损伤诊断方法及其发展方向,从模态参数识别方法和动力学损伤诊断方法出发,归纳分析各种方法的研究现状与进展、优缺点以及应用中存在的问题及其展望。结果表明:模态识别领域的研究热点是环境激励下非平稳信号的模态识别;动力学损伤诊断领域的研究热点是将不同的损伤诊断方法结合,以及引入先进信号处理技术和智能算法;现有研究成果应用于在役海洋平台时面临的主要困难是实测模态信息不完备;将诊断结果同安全评价及剩余寿命预测建立联系,是在役海洋平台动力学损伤诊断的发展趋势。
[Abstract]:In order to find out the dynamic damage diagnosis method and its developing direction of in-service offshore platform, the research status and progress of various methods are summarized and analyzed based on modal parameter identification method and dynamic damage diagnosis method. Advantages and disadvantages, problems and prospects in application. The results show that the research focus of modal recognition is modal recognition of non-stationary signals under ambient excitation. The research focus in the field of dynamic damage diagnosis is the combination of different damage diagnosis methods and the introduction of advanced signal processing technology and intelligent algorithm. The main difficulty in the application of existing research results to existing offshore platforms is that the measured modal information is not complete, and it is the development trend of dynamic damage diagnosis of in-service offshore platforms to establish a link between diagnosis results and safety evaluation and residual life prediction.
