Study to Simulation System for Load on Shearer Cutting Drum and Application

The paper studies load distribution status on shearer cutting drum while it works, puts forward load calculation method used for strength verification of parts of mining machine. Based on average cutting resistance modal, rated torque of cutting motor is matched with simulation algorithm to reversely calculate impedance strength of coal- rock and integrated stress situation of cutting drum. Moreover, a set of simulation analysis software for load of cutting load is developed on basis of Matlab.
