| 摘 要： | 根据导管架平台的结构特点，建立了导管架平台有限元模型。对其进行模态分析，获得前3阶固有频率和模态振型，计算结果与实测结果相符合，表明导管架平台的有限元模型是准确的。在此基础上，对导管架平台施加风、海流静载荷及动冰载荷，进行导管架平台的动力响应分析，获得了导管架平台各个关键点的位移和加速度响应曲线。

| Abstract: | Finite element model of offshore fixed jacket platform is built according to actual structure of it. Analysis of dynamic characteristics for the platform is made by using the method of dynamic finite element, and its 3 preceding modes are obtained. The calculating results are very close to the testing results,so the calculating model of the platform is valid. On the basis of the analysis,the ice-induced response of offshore fixed jacket platform is calculated by exerting wind, current drift static load and dynamic ice force on offshore fixed jacket platform, to obtain the displacement and acceleration dynamic response curves of each key point for offshore fixed jacket platform. |
