Abstract

The invention discloses an aeroengine reverse push door switch motion endurance test device which comprises a reverse push door switch motion control hydraulic system and a reverse push door switch motion control measurement display system. The hydraulic system comprises a hydraulic oil tank, hydraulic actuators which push a reverse push door to open and close, a pressurization oil pump, a check valve, an oil pressure control valve which is arranged on an oil pipeline and a return pipeline, and a switch control valve which controls opening and closing of the reverse push door, wherein the pressurization oil pump and the check valve are arranged on the oil pipeline. The control measurement display system comprises a detection circuit which detects the state of a reverse push door lock, a detection circuit which detects the state of the switch control valve, a detection circuit which detects the state of the position of the reverse push door, a reverse push door opening timing circuit and a reverse push door closing timing circuit. The test device provided by the invention has the advantages of low manufacturing cost, reasonable work logic design, good reliability, clear operation display and the like.

Description

technical field [0001] The invention belongs to the technical field of reliability testing of component systems in the development and production of aero-engines, and in particular relates to a special device for carrying out durability tests on the opening and closing movement of a reverse push door in an aero-engine reverse thrust system. Background technique [0002] As we all know, the development and production of aero-engines is a jewel in the crown of the industrial manufacturing field. The design and manufacturing level of aero-engines represents the top level of a country's industrialized manufacturing technology. At present, only the United States, Britain, Russia, France and my country have the ability to independently develop aero-engines in the world. Relatively speaking, there is still a big gap between the development level of my country's aero-engines and the world's advanced level. The development of aero-engines involves all aspects of machinery, electron...
