摘　　要：水下夹桩器是一种广泛应用于海洋石油平台建设的液压夹具。水下夹桩器压块齿支撑导管架,提供很大的支持力。在水下夹桩器压块齿设计中引入基于有限元分析的优化设计过程,完成了压块齿的结构优化设计。阐述了基于有限元分析的优化模型建立,利用ANSYS软件完成了优化计算,得到了优化结果,并将该结果与理论计算结果进行了比较。分析结果显示,将基于有限元分析的优化技术应用于水下夹桩器压块齿的设计是一种有效的方法,优化后的结构特性与受力状况得到改善,设计结果满足工程要求。Underwater skirt pile gripper is a kind of hydraulic gripper. It is widely applied to the construction of offshore oil platform. Tjhe platform is supported by pressing block teeth. Optimal design based on finite element analysis was introduced into the structure of pressing block tooth for underwater skirt pile gripper. The optimal design model was built and calculated by ANSYS. The result of optimal design was gained, and compared to the theoretical calculation result. It was revealed that the application of optimal design process based on finite element analysis was useful in the pressing block tooth of underwater skirt pile gripper design. The structure charoctenstics and force status of the optimal design were improved, and the engineering demands were well satisfied.
