In order to simulate the high-pressure and high-rise working environment of the aviation actuator for pulse testing,a T-type pulse system was designed,in which a pressure sensor and an electro-hydraulic servo valve were adopted to form a closed-loop control,and pressure was built by controlling the hydraulic oil flowing into the low pressure chamber of the booster cylinder through the servo valve.Based on the pressure-flow mathematical models of accumulator,electro-hydraulic servo valve and booster cylinder-workpiece,a simulation model was built based on AMESim,and the influence of different workpiece volume and pulse rate on the dynamic performance of the system was compared and analyzed.The simulation results show that the system pressure is rapid built by the accumulator instantaneous flow,after the release of energy,the hydraulic pump needs to add 0.25 L hydraulic oil to the accumulator in a cycle;in order to ensure the pressure rise rate,the minimum flow capacity of the system is 250 L/min.According to the simulation results,the key components of the system were selected to build a pulse test bench.The test bench realizes the T-type wave with peak pressure of 42 MPa and a rise rate of 1 100 MPa/s,and stabilizes 200 000 pulses,which verifies the correctness of the simulation analysis.
