自升式钻井平台结构设计与有限元分析

Structural Design and Finite Element Analysis of Self-Elevating Drilling Unit

自升式平台的设计工程复杂、投资大、设计周期长，设计时应严格按照设计程序进行。通过对350英尺自升式平台的设计阐述了有限元分析的一般流程，介绍了自升式平台各组成模块的工作机理以及有限元分析，指出了结构设计中需要注意的问题。

The design of a self-elevating drilling unit which required large investment was complex and time consuming. Thus, the design should be carried out strictly according to the process. This paper described the general process of finite element （FE） analysis throughout the structure design of a 35Oft self-elevating drilling unit. The working mechanism of the main components of the self-elevating unit was described together with corresponding FE analysis. The key aspects for structure design were also pointed out.
