Computer Simulation of Controlled Hydraulic Impactor System
In view of general impactor whose parameters can’t be adjusted continually in different conditions, a kind of controlled hydraulic impactor is introduced. Its non-linear mathematical model and simulation model are established. In simulation environment, adjusting opening pressure of pilot valve, supply oil volume and charging pressure of accumulator respectively, influences on the working performance are investigated. Simulation results prove that, working principle of controlled hydraulic impactor is available and its impact performance is superior to traditional impactor. This provides theory basis for innovation and production of a new generation impactor.
