Civil aircraft hydraulic energy system is an important functional system of aircraft, which plays a vital part in load control. When the energy system has insufficient pressure, the load control accuracy and response speed will decrease, which will directly affect the aircraft Mobility, safety and reliability. This paper takes an example of 35 MPa right hydraulic energy system of aircraft, and explores the method of system-level steady-state pressure analysis of the hydraulic energy system of civil aircraft through computer simulation based on AMESim software. Firstly, it analyzes the pressure loss of hydraulic energy system and calculates the available pressure of hydraulic users. Then, the analysis model of the right hydraulic system is built through AMESim simulation. Finally, the steady-state pressure analysis result of the right hydraulic system is obtained to determine the minimum temperature of the full performance of the right hydraulic system. At the same time, this analysis method has practical significance for improving the efficiency of design, evaluation and optimization of large hydraulic energy system of civil aircraft.
