- 摘要:
- 管节点作为海洋平台结构中十分重要且薄弱的环节,其极限强度分析是海洋平台安全评估的重要内容,也是一项十分复杂的工作,选择正确的方法和分析手段是得到准确分析结果的前提。文章应用MSC.PATRAN软件建立平台管节点分析的有限元模型,分别使用局部模型法和嵌入式模型法对管节点进行分析,对比其计算结果,认为采用嵌入式模型法更为精确。
Tubular joint is a kind of very important and weak link of offshore platform structure.Its ultimate strength analysis is significant to the safety assessment of offshore platform and is a very complex task.So choosing the right methods and means is the precondition to get accurate results.In this paper,the software MSC.PATRAN is applied to establish the accurate finite element model of tubular joint analysis and the model is solved with the local model and the embedded model approaches respectively.By comparing the calculated results,it is shown that the result obtained from the embedded model approach is more accurate.2001,1(1): 12-15,4 收稿日期：2010-8-16分类号：TE54;TE951作者简介：赵开龙(1983-),男,山东德州人,工程师,2009年毕业于哈尔滨工程大学船舶与海洋结构物设计制造专业,硕士,现从事结构分析工作.参考文献：
