Abstract

High-speed aviation pump often used as a constant pressure source of hydraulic servo system, which is essential to the maneuverability and stability of the whole system, and requires its regulating mechanism have good stability and quick response. In actual operation process, the variable piston chamber of the high-speed pump often appears low frequency oscillation phenomenon, which causes the swash plate to produce corresponding low frequency vibration, and then causes the pressure fluctuation of the outlet, affecting the stability of the control system. In this paper, the influence factors of constant pressure variable control stability of high-speed pump are analyzed by means of theoretical analysis, AMESim simulation analysis and actual test. The results show that the stability margin of the system can be precisely controlled by changing the piston clearance and then the total leakage coefficient of the pump, and the stability of the control system can be effectively improved.
