摘要
海洋井架的结构损伤检验是关系到井架安全的重要指标,利用模态分析的方法暂时没有在井架检验中被应用。通过SAFI有限元分析软件模拟井架受损状态,并与原状态进行对比,有效的检查到井架受损情况。此次检验将对以后基于模态分析检验井架奠定了基础。
The structural damage detection of offshore mast is an important index related to the safety of mast. The method of modal analysis is not applied in mast test. In this paper, the SAFI finite element analysis software is used to simulate the damage status of the mast, and it is compared with the original state so as to effectively check the mast damage. Thus the test would establish a basis for the subsequent mast damage identification based on the modal analysis.
