本文简述了在固定式海洋平台动力分析程序DASOS-J(D)中发展及使用的各种动力分析策略。它以结构分析通用程序JIGFEX为基础,全部动力分析都可采用三维多层子结构模型。在自振特性计算、确定性或随机性动力响应分析等一系列模块中,不但考虑了我国规范和国际惯例的要求,而且发展了一些新的有效方法,使动力分析更为准确、方便与经济。
This article briefly describes various dynamic analysis strategies developed and used in the dynamic analysis program DASOS-J(D) of a fixed offshore platform. It is based on the general structural analysis program JIGFEX, and all dynamic analysis can use three-dimensional multi-level sub-structure model. In the series of modules for calculation of natural vibration characteristics, deterministic or random dynamic response analysis, not only the requirements of China’s regulations and international practices are considered, but also some new effective methods have been developed to make dynamic analysis more accurate, convenient and economical. .
