Accelerated life test method of aircraft brake system

The invention relates to an accelerated life test method of an aircraft brake system. The environment conditions of applying temperature stress, vibration stress and the like in a combined way are adopted, the operating conditions are added and the operating frequency of the whole system are increased during the test process, so that the hidden fault dangers of the brake system are stimulated, and the test time is shortened. The method is circularly carried out according to the test profile during the test process until the required reliability index is reached. The power-on operating conditions, the brake applying pressure operating conditions and the rotating speed change conditions in use are converted into the test time according to the applied operating frequency, and the operating frequency adopted in the test is greater than the actual operating frequency in use. The reached reliability index is assessed according to the method in GJB1407 and recommended degree of confidence after the test is finished, and the degree of confidence for assessing the reliability index is 90%; and the empirical coefficient of life assessment is 1.5. The purpose of performing the accelerated life test on the brake system is realized by verifying whether the brake system has hidden fault dangers under various operating states.
