中文摘要：
利用有限元分析软件ANSYS、Workbench,对自升式海洋平台桩腿桩靴进行在极端工况下的静力、模态、波流耦合等分析。利用理论基础对桩腿桩靴受到的各种海洋环境载荷进行计算分析,并结合中海油能源发展股份有限公司采油服务公司及中国船级社《海上移动平台入级与建造规范》的实际数据,对其数值解和理论值进行比较分析,以验证有限元方法求解的可靠性。研究结果对于提高自升式海洋平台桩腿桩靴质量有显著意义,并可为现场应用提供借鉴。
英文摘要：
Based on the Solidworks, finite-element analysis Software ANSYS, Workbench, the pa- per carry on the strength check of offshore platform＇s leg and sabot and obtain analysis of stress and strain in harsh environment. For example,static analysis, wave and current coupling, modal a- nalysis. In the paper based on the theory of leg and sabot by all kinds of Marine environment load calculation and analysis,what＇s more combining with the data from the CNOOC Energy Develop- ment Company Limited, production service company. The numerical solution and theoretical com- parison analysis proved the correctness of the problem solve by using the finite element method. Research results have significant meaning for the improvement of self-elevation offshore platform leg and sabot can provide reference for the application.
