自升式平台主船体结构强度有限元分析

Analysis of the Main Hull Structure Strength of Jack-up with Finite Element Method

随着海上油气业的发展，自升式钻井平台得到广泛应用，由于其常年工作于恶劣的海洋环境中，保证其安全尤其重要。以某自升式平台为例，介绍了利用有限元分析软件PATRAN，对自升式海洋平台主船体结构强度进行有限元分析的过程、处理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相应说明。

With the development of offshore oil and gas industry, the jack-up rigs are widely used, because they can work in the worst marine environment yearly .It is particularly important to ensure their security. In this paper, taking a jack-up platform as an example, the software of finite element-PATRAN is used to analysis the main hull structural strength of jack-up marine platform. Introduce the process of finite element analysis, corresponding treatment and the attention should be paid and the calculation, the load issues such as the imposition to are introduced. The issue of working conditions and other notes are presented.
