Problems solved by technology

By changing the structure design of the sensor bracket in the vibration measurement technology, it solves the tediousness of repeated debugging distance and angle. Due to the limitation of the volume of the magnetic meter seat itself, the existing vibration measurement technology cannot realize the dense arrangement of infrared displacement sensors with small spacing in the axial direction of the rotor. There are measurement errors caused by inaccurate placement of the magnetic base in the vibration measurement technology, and the difficulty in positioning the small angle offset or small distance offset that occurs when the magnetic base is finally locked.

Abstract

The invention relates to a vibration measuring device and a digital twinning method for an engine multi-size outer profile rotor. The device includes a vibration measuring component and a data acquisition component; the vibration measuring component includes a column, a beam structure, and a three-degree-of-freedom sensor bracket An adjustment mechanism and a base; the data acquisition component includes a test computer, an LMS test system, an infrared displacement infrared displacement sensor, a rotary encoder and a USBCAN device. The invention can solve the cumbersomeness of repeatedly adjusting the distance and angle. Due to the volume limitation of the magnetic meter seat itself, the existing vibration measurement technology cannot realize the dense arrangement of infrared displacement sensors with small spacing in the axial direction of the rotor. The magnetic meter seat swings in the existing vibration measurement technology The problem of measurement error caused by inaccurate placement and the difficulty in positioning of small angle offsets or small distance offsets when the magnetic meter base is finally locked. And the digital twin technology is applied to the test of the rotor of the aero-engine to improve the advancement of the vibration measurement technology of the rotor of the aero-engine.

Description

technical field [0001] The invention relates to the technical field of aero-engine testing, in particular to a vibration measuring device and a digital twinning method for an engine multi-size profile rotor. Background technique [0002] The existing vibration measurement technology is mainly a vibration measurement device composed of a distance regulator, an infrared displacement sensor fixer, etc., plus an infrared distance infrared displacement sensor and a data collector to form a vibration measurement system, which is widely used in machine tool shafts and Engine rotor or other rotating machinery vibration testing occasions. Existing distance regulators are generally composed of magnetic gauge bases and fixing bolts, such as the distance demodulator disclosed in patent document CN104776987A. Most of the existing vibration measuring devices are fixed on the base with a magnetic base, on which the slide rail is fixed by bolts, the sensor bracket is fixed by two bolts at ...
