Abstract
In order to explore the effect of the tooth structure of the cutter tooth on its strength and the mechanical properties of the cut coal rock, the cutter teeth of JBA69, GC-20116 and SrFc1007 were selected as the research objects, and the cutter tooth area and cutting surface area were calculated Strength and build a mechanical model. The ABAQUS finite element software was used to establish three finite tooth models of cutter teeth for cutting coal and rock. The mechanical characteristics and stress and strain were analyzed according to the simulation results. The results show that the maximum stress and strain of the cutter teeth is at the tooth shank at the port of the tooth seat. The average cutting force of the cutter tooth GC-20116 is the smallest, and the average cutting force and traction force of the cutter tooth SrFc1007 are the largest. SrFc1007 cutter tooth tip area is the least stressed, and JBA69 cutter tooth tip area is the most stressed. SrFc1007 cutter teeth are subject to the most stress.
