DEM Simulation Study of Crosscutting Speed for the Cutting Header

Abstract

For studying the working performance of the cutting header, the paper puts forward using DEM to study its dynamic breaking process when it is for cutting coal rock. The model of cutting header and the model of the two-dimensional DEM simulation analysis are set up separately. By applying reasonable mechanical model into coal rock particles and the cutting header, DEM simulation analysis of its cutting process is carried out. Such analysis is taken at different cutting speed. Then, the way of selecting working parameters is got. It preliminarily proves the feasibility of using DEM to analyze the working procedure of the cutting header and it provides a new research method for its optimization design.

Investigation of the Destruction Process of Potash Ore with a Single Cutter Using Promising Cross Cutting Pattern

“…where T 2 -time of occurrence of the small intermediate cleavages, s. Verification of the results of the aforementioned theoretical studies can be done by conducting experimental studies on a laboratory bench where potash ore it cut with a single cutter [19][20][21].…”
