【摘要】：本文根据采煤机截齿的截煤特点,从采煤机的截割对象一煤出发,经过推导得到截齿截煤的数学模型,从而分析了滚筒的受力和所受转矩情况,并得到采煤机行星减速器关键零件的力学模型。然后利用MATLAB软件对采煤机关键零件的数学模型进行仿真,得到采煤机行星减速器关键零件的受力和转矩的关系变化曲线,并加以分析。说明关系曲线产生的原因,而后利用对Pro/Engineer的应用对行星减速器进行建模得到三维实体图,并保存成IGS格式,这样就可以通过两个软件的接口将Pro/Engineer中绘制好的各关键零件的模型导入ANSYS Workbench中,出现减速器关键零件的有限元模型,通过ANSYS Workbench对行星齿轮传动减速器进行有限元处理,得到的行星减速器关键部件：行星架、行星轴、太阳轮的应力、应变和总变形的分析云图,并加以分析,找到几个关键位置受力的原因,通过本论文对今后采煤机向小体积、大功率的优化提供可靠的数据分析理论。
[Abstract]:According to the coal cutting characteristics of shearer, the mathematical model of cutting coal is derived from the coal cutting object of shearer, and the force and torque of the drum are analyzed. The mechanical model of the key parts of the planetary reducer of the shearer is obtained, and then the mathematical model of the key part of the shearer is simulated by MATLAB software, and the relationship between the force and the torque of the key part of the planetary reducer of the shearer is obtained. The reason of the relationship curve is explained, and then using the application of Pro/Engineer to model the planetary reducer to get the three-dimensional solid graph, and save it to IGS format. In this way, the model of each key part drawn in Pro/Engineer can be imported into ANSYS Workbench through the interface of two softwares, and the finite element model of the key parts of reducer appears, and the planetary gear reducer can be treated by finite element method through ANSYS Workbench. The key components of planetary reducer: planetary frame, planetary shaft, sun wheel stress, strain and total deformation are analyzed and analyzed to find out the causes of several key positions of the force, and through this paper to the shearer to small volume in the future, High power optimization provides reliable data analysis theory.
