【Abstract】 In this paper , a new kind of compound transmission-Pneumatic-Hydraulic Combination Control (PHCC) servo system is put forward , the basic principle and the structure are introduced and the mathematical model of the power mechanism is given. The simulation and calculation with the normal parameter for the system are completed. The main performance parameters and the corresponding frequency characteristics are also analyzed. The paper explains that the system has high static and dynamic rigidity, the adjustable damping ratio, the function of positioning and locking by controlling the hydraulic damping force when the liquid is led into the normal pneumatic servo system. This system has wide practical application prospects.更多还原
