Cutting Test and Finite Element Analysis of Plow Pick

The pick is the working part of coal plow, cutting performance very important for efficient production mine. In order to analyze dynamic characteristics plow during process, a test platform was built. force and vibration head were obtained through test, relationship between speed depth analyzed. study influence different alloy shapes on pick, two kinds designed: with chip bit conical bit. finite element method used establish model, numerical simulation carried out. research results show that caving effect better than bit, but resistance greater When angle 60°, smallest increases increase installation angle. maximum error by methods 8.41%. verified simulation. According results, types adopted in which installed positions. Through analysis actual state it found damage form consistent result
