The independence of the various test control manners, the flexibility of working manner conversion and the accuracy of various parameter test are ensured, and the device is convenient to implement, wide in applicability and flexible to operate.

Description

technical field [0001] The invention relates to the field of aircraft test system design, in particular to a comprehensive joint test control method and device for aircraft landing gear, which is especially suitable for the comprehensive joint test test of aircraft landing gear systems, cabin doors or other electromechanical hydraulic systems. Background technique [0002] The comprehensive joint test of the aircraft landing gear system is used to verify the landing gear retraction / release function, position indication function, control logic, door opening and closing function, and monitoring the pressure and flow parameters of various key points of the hydraulic system. From the early stage of system development, various system verifications such as retractable mechanism, manual debugging test of hydraulic system, system control logic test, incomplete system comprehensive test, and whole system comprehensive test are required. The common comprehensive joint test of aircraft...
