Simulation And Analysis Of Dynamic Characteristics Of Hydraulic Impact System Of Impact Coal Cutter Based On Software Simulink

The coal impact breaking mechanism and impact coal cutter were introduced in the paper, the primary task of this project, study on the dynamic characteristic of hydraulic impact system of impact coal cutter, was pointed out. Based on the detailed analyzing of impact system working process, the differential eguation of the system was got, and the mathematical model of the hydraulic impact system was builted, on basis of the mathematical model, By using of dynamic simulation function of Matlab ,the author has built the simulation model of the impact system based on software Simulink and run it after inputting the parameter ,the dynamic graph curve of impact velocity and presser of oil and position of knife rest were got, and the dynamic characteristic of impact system was analyzed,the simulated results are accorded with the fact,and some rational parameters can be found. The finding will provide necessary theory dependence for the hydraulic impact system, which is in the designing and issignificant for impact coal cutter, which is in the perfecting.
