摘要
主要研究了采煤机的截割部行星组件,利用仿真软件对摇臂系统进行了动力学仿真,得到了行星组件所承受的载荷,对其进行有限元分析和寿命分析,获得了行星组件受到的应力分布特性、变形情况、疲劳寿命等信息。根据行星组件现有特性进行分析和优化,对优化后的模型进行了仿真研究,证明该设计对采煤机行星组件的性能有明显提升,符合设计要求。
We mainly do some research on the planetary components of the shearer cutting unit. The rocker arm system is analyzed by using the simulation result and the load withstood of the component is calculated. Then we analyzed the fatigue life of the components by the finite element analysis. The stress distribution of the component, the deformation, the fatigue life and other valuable information can be obtained. According to the current features of the planetary components, we do some optimum designs. Then analysis of the new design is researched. The result shows that the new design improves the performance of the planetary components, and the design can comply with the design requirement.
