摘要
用MSC/PATRAN建立一工作水深为122 m的JU2 000E型自升式平台三维模型。通过对模型进行模态分析,得到平台模态质量和模态刚度矩阵,然后采用波浪谱分析方法,研究平台在随机波浪力作用下的动力响应,以图为平台正常作业和维护提供参考。
With MSC/PATRAN to establish a 3D model about jack-up platform JU2 000E works at 122 meters deep water.The model mass and model stiffness matrix of platform are gotten by model analysis.Wave spectrum analysis method used to research the dynamic response of platform under the action of random wave.The result will be as a reference to normal operation and maintenance.
