Abstract

The invention relates to a comprehensive detection system for an aero-engine vibration device, which relates to the technical field of flight parameter system inspection devices and is provided with a fixed-frequency output unit, a variable-frequency output unit, a control switching unit, a comprehensive display unit, a g value detection and direct-current output unit and a high-precision power supply unit, wherein the control switching unit controls the output frequencies of the fixed-frequency output unit and the variable-frequency output unit, the comprehensive display unit displays the output frequencies of the fixed-frequency output unit and the variable-frequency output unit, and the g value detection and direct current output unit measures and outputs microampere current. According to the system, the frequency output of the fixed-frequency output unit and the variable-frequency output unit is controlled by controlling the switching unit, so that the vibration sensing parameter acquisition accuracy of the flight parameter system is effectively improved, and the service life of an aero-engine is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of inspection devices for flight ginseng systems, in particular to a comprehensive inspection system for vibration devices of aero-engines. Background technique [0002] When an aeroengine is working, its body will vibrate, especially for propeller aircraft and rotorcraft. There are many sources of engine vibration, such as various rotating parts (compressor-turbine rotor, reducer), the stiffness, mass and damping of the support system, as well as manufacturing errors, force deformation, uneven flow field and air flow factors such as strong disturbances. Aircraft engine vibration directly affects its normal work and life, and at the same time it will cause aircrew fatigue, inaccurate instrument indication and easy damage, pipeline rupture, fatigue fracture of engine and aircraft structure, etc. [0003] The vibration sensing parameters collected by the flight parameter recording system include amplitude, v...
