The model uses a one-dimensional array to simulate the scraper conveyor through numerically simulating the changes of each element in the array that correspond to the changes in the load of the scraper conveyor with the coal mining machine position change. The MATLAB software is used to develop the software platform of the scraper conveyor's load spectrum simulation system to avoid the tedious data input process. Through computer simulation, this paper compares the method with the conventional method, and the simulation results verify its feasibility and advantage. This method can greatly simplify the calculation process of the load spectrum of the scraper conveyor and can obtain cargo distribution at any time and position of the scraper conveyor. The method provides the database for the running resistance of the dynamic characteristics of the scraper conveyor, the tension variation and the real time adjustment.
