Abstract:According to the model of aircraft brake system in the ground plane test of brake pressure vibration problems, the different pipe models and length, return pressure, natural frequency and damping ration of the brake control valve and other parameters were set using the batch function of AMESim, the aircraft brake pressure control system was analyzed. The results show that the resonance of the aircraft brake pressure control system is a fluid solid coupling vibration caused by the interaction of brake control valve and brake pipe. Changing the parameters of brake system in the pipeline, back pressure, brake control valve can effectively weaken the brake system pressure fluctuation.
