模拟

According to the operating characteristic of the fluidics and the theory of hydromechanics, a dynamic model of the impactor is established, in order to bring the percussive rotary drilling technology into full play. Also a simulation program is developed to calculate the working properties of the impactor. By using the simulation program, the variation laws of the basic parameters of the hydraulic impactor under different structural parameters and hydraulics are obtained.
