坐底式海洋平台整体结构强度有限元分析

Finite Element Analysis of Structural Strength for Bottom-Supported Drilling Platform

平台整体结构强度分析是保证平台安全的首要条件。以“胜利二号”坐底式钻井平台为实例，介绍了利用有限元分析软件ANSYS对坐底式海洋平台整体结构强度进行有限元分析的过程、方法及应注意的问题，并对计算工况、载荷的施加等问题进行了说明。

Taking ShengLi No.2 bottom-supported drilling platform as an example, the process, methods and key problems of the finite element analysis applied to the bottom-supported platform, with the software ANSYS being used, are introduced in the paper. Several problems, such as calculation condition, load exerting, etc., are explained.
