海洋导管架平台K型节点碰撞性能研究

Study on Collision Behavior of K-joint in Offshore Jacket Platform

管节点是海洋平台设计研究中的一个重要内容。本文以海洋平台中最常见的K型节点为研究对象,用MSC/Dytran数值模拟了K型节点在撞击荷载作用下的损伤特性,对平台设计中常见的管节点加强措施与未加强措施的管节点进行了比较研究,研究表明采用加强筋措施效果较好。

In the research on the offshore platform,the tubular joint is a key point. The K-joint adopted widely in the offshore platform structure is investigated. The mechanism of the K-joint under collision loads is studied through the numerical simulation by using the software MSC/Dytran. Several strengthening schemes are compared to the original tubular joint. Results show that the strengthen tendon is efficacious.
