对采煤机截割部行星组件进行了研究。利用Pro/E,MATLAB,ADAMS,ANSYS,NSOFT构造的协同仿真环境,对摇臂系统进行了多体动力学仿真,计算出系统中构件所承受的载荷,编辑生成行星组件的载荷文件,并对行星组件做了有限元分析和疲劳寿命分析,得到行星组件的应力分布情况、变形情况、固有模态信息、频率响应曲线、疲劳寿命值,根据分析结果对行星组件进行结构优化。通过对优化后的行星组件模型的虚拟仿真,验证了模型的合理性,保证了富含硬结核体的薄煤层采煤机的成功研制。
The shearer cutting unit planetary components were studied. The multi-body dynamics simulation of the rocker arm system is carried out by using the co-simulation environment of Pro / E, MATLAB, ADAMS, ANSYS and NSOFT to calculate the load borne by the components in the system and edit the load file of the planetary components. The planetary components were analyzed by finite element method and fatigue life analysis. The stress distribution, deformation, inherent modal information, frequency response curve and fatigue life of the planetary components were obtained. The planetary components were optimized according to the analysis results. Through the virtual simulation of the optimized planetary component model, the rationality of the model is verified, and the successful development of the thin coal seam shearer rich in hard nodules is guaranteed.
