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

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.
