DG585大钩的磨损有限元分析
|
摘要
介绍了大钩的工作特点和钩体的磨损条件,并对钩体的磨损降级使用条件和判废标准进行了分析。然后利用ANSYS Workbe nch软件对钩体在不同降级使用的载荷工况和磨损状态下分别进行了有限元分析。根据分析结果指出了钩体降级使用注意事项和对钩体进行有限元磨损分析的优点,同时指出了减少或削减应力畸变点应力数值的办法及利用三维实体单元分析的好处,最后指出了钩体减小应力集中的措施。
This paper introduces the working characteristics and wear condition of the hook, and then analyzes the wear degradation conditions and the standards of scrap judgment. Then the finite element analysis of the hook body under different load conditions and wear conditions is carried out using ANSYS Workbench. According to the results of the analysis, it points out the precautions for the degradation of the hooked body and the advantages of finite element wear analysis of the hooked body. At the same time, it points out the methods to reduce the stress value of stress distortion points and the advantages of using 3 D solid element analysis. At last, the measures to reduce stress concentration are pointed out.
