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。在水下夹桩器设计中引入有限元分析的优化设计过程,介绍了ANSYS优化设计步骤和ANSYS参数化设计语言(APDL),并以水下夹桩器液压缸壁为研究对象,应用参数化设计语言完成了不同系列水下夹桩器液压缸壁的结构优化设计。优化后的结构特性与受力状况得到改善,设计出来的结构满足工程要求。分析结果显示,将APDL语言面向对象软件设计应用于水下夹桩器是一种有效的方法。Underwater skirt pile gripper is a kind of hydraulic gripper,and it is widely applied in the construction of offshore oil platform. Optimal design based on finite element analysis was introduced into the hydraulic cylinder of underwater skirt pile gripper design in this paper. The optimal process and ANSYS Parametric Design Language were introduced,and the optimal design of hydraulic cylinder of different series underwater skirt pile gripper was finished in APDL. The speciality and force status of the optimal structure were improved. And the engineering demands were well satisfied. It＇s shown that the application of objectoriented APDL is useful in the design of hydraulic cylinder of underwater skirt pile gripper.
