【Abstract】 Based on the equivalent mechanics model of single freedom machinery,it is analyzed detaily that machine driving system of the impact coal cutter, the dynamic analysis model of the driving system is set up, the visual software of dynamic simulations is worked out. When working parameters of the machine are inputted, the working states can be simulated. The results showed that the machinery cutting power can be reduced markedly in using this impact cutting coal.更多还原
