基于自行设计建造某小型自升式平台，根据《海上移动平台入级与建造规范》，采用 MSC.Patran/Nastran 有限元分析软件建立有限元模型；针对自升式平台在发电作业、自存两个典型工况进行结构强度计算和模态分析，获得平台的模态振动规律。分析结果显示，该平台结构强度满足发电作业工况和自存工况。%Based on a small jack-up platform which is designed and built by the University, this paper establishes a finite element model according to“Rules for the Classification and Construction of Offshore Mobile Platform”by the finite element analysis software MSC. Patran/Nastran. In view of the jack-up platform under the working condition of power operation and self-survival, it carries out structural calculation and modal analysis to obtain the law of modal vibration. The results show that the structural strength of the platform can meet the working condition of power operation and self-survival.
