摘　　要：基于某深海张力腿平台结构,采用SESAM软件建立该平台的水动力分析计算模型,通过计算得到该平台的RAO和极值加速度;进而采用ANSYS软件建立该平台上部钻井设备模块分析计算模型,以惯性力的形式考虑平台运动对上部结构强度分析产生的影响,并对钻井设备模块进行准静力分析,为张力腿平台这类移动式平台上部设备模块结构的强度分析提供研究思路和技术支持。The hydrodynamic analysis model of the structure of a tension leg platform （TLP） in deep sea are established by SESAM, resulting in the response amplitude operator （RAO） and the extreme acceleration of the TLP. The calculation model of the drilling equipment module on the upper part of the TLP are set up by ANSYS. The influence of the TLP motion on the upper structure strength is considered as an inertial force. A quasi-static analysis is also conducted for the drilling equipment module. It can provide research strategy and technical support for the structural strength analysis of the upper equipment module on the mobile platform as the TLP.
