张力腿平台的静态分析
首发时间:2008-10-29
摘要:张力腿平台凭借着在深海作业中具有运动性好、抗恶劣环境作用能力强、造价相对于固定式平台低等优势,在20多年的实践中不断发展,已形成一种典型的结构形式。本文在“平行张力腿”假定的情况下,对张力腿平台进行了静态的分析,静态分析是动力分析的基础,不但可以为动力分析提供必要的参数关系,而且对张灵体腿平台的结构设计也提供了一些重要的科学依据。首先得到了张力腿平台水平偏移、垂直生沉、张力腿内张力及其张力腿刚度、初始张力之间定性非线性关系,然后编制运算程序进行计算。从分析结果可以看出:张力腿的刚度、预张力对张力腿平台各参数的影响显著,它们是平台重要设计内容。

The Static Analysis of TLP
Abstract:TLP platform has become one of the typical construction form during the 20 years’ development, because of its motility, resistance to hostile environment and comparatively low cost. Under the assumption of “parallel TLP”, static analysis of TLP has been carried out to research the response of TLP under external loads and is key problems to be considered in the practical design of TLP. The static analysis is the foundation of the dynamic analysis, providing necessary parameter relation for the construction design phase. According to the results, almost all the parameters are sensitive to the stiffness and pretension, which are of great importance in the design.
