Abstract

The invention discloses a pollution resistance test method and a test system of an aircraft integrated brake module, belonging to the technical field of reliability engineering. The test method includes: system preparation, pollutant selection, system inspection and start-up test. The pollution level is gradually increased from NAS6 to NAS9. The test system includes: drive motor, thermometer, fuel tank, outlet pressure gauge, hydraulic pump, sampling port ball valve, outlet ball valve, safety valve, heat exchanger, unloading valve, flow meter, one-way valve, oil filter, A port Pressure gauge, B port pressure gauge, oil filter differential pressure gauge, injection port ball valve, pollutant injection chamber, throttle bypass valve 1, throttle bypass valve 2 and bypass valve. The current offset and performance parameters of the servo valve of the integrated brake module under different pollution levels are obtained by using the method and system of the present invention. Through the current offset and performance parameters under different pollution levels, it is possible to judge the pollution of the integrated brake module to different levels resistance to contamination.

Description

technical field [0001] The invention belongs to the technical field of reliability engineering, and relates to a pollution resistance test method and a test system of an aircraft integrated brake module. Background technique [0002] Aviation hydraulic valve is an important control element of today's aviation hydraulic system, which is related to the safe flight of aircraft. Solid particle contamination is one of the key factors affecting the performance and reliability of aviation hydraulic valves. Due to the unavoidable presence of a large number of particle pollutants in the hydraulic system, after the hydraulic valve has been working in the polluted oil for a period of time, it is very easy to produce faults such as polluted wear, polluted stuck and polluted blockage, and even lead to failure. [0003] Among the current hydraulic valve pollution resistance test methods, it is mainly to test the contaminated oil of a certain pollution level, and then evaluate the polluti...
