摘　　要：以斗山DX230LC-9C中型液压挖掘机为研究对象,基于UG/ANSYS的中型液压挖掘机斗杆优化设计方法,在原有尺寸参数基础上利用UG软件建立了整机简化三维模型。根据挖掘作业环境的复杂程度确定工况二即斗杆油缸单独工作和工况三即斗杆油缸、铲斗油缸及动臂油缸同时配合工作的2类典型危险工况。利用ANSYS软件求解典型危险工况下斗杆的应力变形,针对局部薄弱部位进行结构优化。仿真结果表明,优化后斗杆在工况二下最大应力值、最大变形值分别减小6.9%、1.7%;在工况三下最大应力值、最大变形值分别减小6.4%、1.5%。优化设计方法效果显著,为同类型工程机械整机设计及静力学分析提供一种实用性参考。The optimal design method of medium hydraulic excavator stick based on UG/ANSYS is studied.Taking medium hydraulic excavator in Doushan as the research object,a simplified three-dimensional model of the whole machine is designed by using UG software based on the original size parameters.According to the complexity of excavation environment,two typical dangerous working conditions are determined:working condition 2,the stick cylinder works separately;working condition 3,the stick cylinder,bucket cylinder and boom cylinder work together at the same time.The stress and deformation of the stick under typical dangerous working conditions are solved by ANSYS software,and the structure is optimized for local weak parts.The simulation results show that the maximum stress value and maximum deformation value of the stick under condition 2 are reduced by 6.9%and 1.7%respectively;Under condition 3,the maximum stress value and maximum deformation value are reduced by 6.4%and 1.5%respectively.The effect of optimal design method is remarkable,which provides a practical reference for the whole machine design and static analysis of the same type of construction machinery.
