Abstract:The rotary impact type hydraulic jumbolter of drive control system was designed. The working principle was analyzed of the hydraulic impact system, the promote system, the rotary mechanism hydraulic circuit and the anticard working hydraulic circuit when jumbolter was working. According to the theory of abstract design variables, the performance parameters were deduced of impact energy E, the impact frequency f, the output power N between relationship of the hydraulic impactor work flow Q (or working pressure p) and accelerate the return stroke of the piston Sj. Modeling and simulation were established based on AMESim software. The influence of hydraulic impact energy, impact frequency and piston displacement and impact power was analyzed when changing system working pressure and push power according to the simulation curve at working of the jumbolter. The simulation results verify the design of rationality and feasibility of the hydraulic pressure drive control system, which offer the theoretical foundation to design the hydraulic jumbolter drive system of optimum control strategy.
