Simulation of Hydraulic Control System for Height Adjustment of Shearer Based on Matlab/Simulink

QI Hai-yong

Abstract

Hydraulic control system for height adjustment of shearer is described,and simulation model is established with Matlab/Simulink.The combination of spring,damping and quality components are used to simulate the load when shearer drum cutting coal.The result of simulation shows that there are great influence on hydraulic control system with impact load acting on hydro-cylinder,and it will be some guide for designing hydro-cylinder and hydraulic control system.
