摘　　要：通过Solidworks软件建立液压启闭机液压缸的三维实体模型,并以有限元分析模块Simulation为平台,对闸门关闭时液压缸活塞杆完全伸出,压力达到最大值18MPa的工况下进行整体结构有限元分析,并结合工程技术标准进行了验证。分析结果表明:该液压缸的强度设计安全可靠,刚度稳定性符合设计规范。基于工作装置的整体有限元分析方法极大地降低了计算分析难度,提高计算结果的准确性,为结构的进一步优化、设计改进提供理论依据。A three dimensional （3D） solid model of the hydraulic hoist cylinder was established in Solidworks software. In the platform of finite element analysis （FEA） Simulation module, the hydraulic cylinder structure was integrally analyzed under the operat- ing conditions that hydrodynamic piston shaft was fully-extended and the maximum pressure was reached 18 MPa in the closed gate, and was verified in relation with the engineering technical standards. The analysis results show that the intension design of hydraulic cylinder is safe and reliable, and the rigidity and stability are up to the design standard. The integrated FEA method based on working device not only greatly reduces the difficulty of computation and analysis, but also improves the accuracy of calculated result. This method provides a theoretical basis for further structural optimization and design improvement.
