Modeling a pulse hydraulic positive-displacement drive with retardation of the striker in phase of back stroke

Modeling methods are used to obtain the calculation relations of the pressure in the working chambers and the velocity of the striker as functions of time and coordinate. Relations are also obtained to describe the dependence of energy and impact frequency, power, and efficiency on the hydraulic resistance of the drain line, the parameters of the pneumatic-hydraulic accumulator, the working volume of the hydraulic cylinder, the mass of the striker, and the capacity of the pump.
