Abstract

The invention discloses an aeroengine vibration transducer double-wire checking and detecting method and an implementation system thereof. The implementation system comprises a main system which is formed by a computer, a controller, a power amplifier, a power supply, a vibration table, a vibration measuring instrument, a digital display No.1 and a piezoelectric accelerator No.1, and an auxiliary system which is formed by a piezoelectric accelerator No. 2, a charge amplifier and a digital display No.2 and is used for detecting the self errors of a vibration system. The checking and detecting method comprises that a computer is used to build a vibration test, the checking and detecting main system detects and displays the vibration signal which is detected by a detected vibration transducer, the auxiliary system detects the self errors of the vibration system, and the detected vibration transducer is checked and detected through eliminating the self errors of the detecting vibration system. By utilizing the method, the problems that a single-wire checking and detecting method of the prior art cannot reflect the vibration system error elimination, cannot correctly judge the detected vibration transducer and the like are solved, and the method has the characteristics of high checking accuracy, high working efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of detection of vibration sensors, and more specifically, relates to a two-line calibration detection method of an aeroengine vibration sensor and an implementation system thereof. Background technique [0002] Aeroengine vibration sensors are components used to monitor the vibration conditions of aeroengines during operation, and are very important to the safe operation of the engine. Therefore, the sensors need to be calibrated before being used in the engine, and the sensors that cannot meet the requirements are eliminated. [0003] The verification and detection of the vibration sensor of the aero-engine has been verified by the single-line detection method for a long time, that is, a detection test of the vibration sensor is created by the computer, and the detection test information created on the computer is input to the controller, and the controller will The detection test information is generated a...
