Based on civil aircraft, a brake system accumulator simulation model is built with AMESim. In this model, the effect of temperature vibration on accumulator during flight envelop is considered. The simulation model is re-produced the accumulator high pressure issue result by temperature vibration. Furthermore, an improvement design is proposed, and the feasibility of the new design is verified by both simulation analysis and flight test. By compar-ing the flight test data with the simulation data, the simulation model is verified and it has competitive performance.
