基于Matlab的纵轴式掘进机截割头切削过程的模拟研究

Simulation Research of Cutting Process of Cutting Head of Longitudinal-axial-roadheader Based on Matlab

介绍了理论截槽以及切屑图的绘制原理,使用Matlab编程实现了截割头切削过程的模拟,画出了切屑图,并给出了每一个截齿在不同工况下的切屑面积和偏载荷系数。应用该程序可快速判断截齿排列在给定的截割参数下是否合理,为截齿排列的设计和检验提供了手段。

Theoretical pick cut and principle of drawing cutting pattern were introduced. Computer program was worked out by Matlab to realize simulation for cutting process of cutting head. The cutting pattern was drawn and cutting area of each pick and its coefficient of bias load were given under different conditions. By the program, the rationality of pick arrangement with certain cutting parameters can be judged quickly and it gives a way to design and test of pick arrangement.
