Abstract

The invention discloses a physical-simulation test processing system for microvibration of a refrigerating machine and a test method thereof. The physical-simulation test processing system comprises a compressor, a compressor bracket, a Z-shaped patch board, a hexagonal patch board, a six-component and eight-sensor perturbation-vibration force testing platform, distributed acceleration sensors, a laser displacement measuring system and a data acquisition and processing system, wherein the refrigerating machine device is arranged on the six-component and eight-sensor testing platform by the patch board, and simultaneously the accelerator sensors are distributed on the refrigerating machine according to the testing requirement. When in working, the refrigerating machine can generate micro-perturbation to the six-component and eight-sensor perturbation-vibration force testing platform. The data acquisition system acquires signals of the eight sensors of the six-component and eight-sensor perturbation-vibration force testing platform, obtains the perturbation-vibration force by a series of calculations and also acquires the signals of the acceleration sensors to obtain acceleration.

Description

technical field [0001] The invention relates to a micro-vibration testing method of a refrigerator, which can be used for dynamic measurement of vibration signals of a micro-disturbance load of a spacecraft refrigerator device on six degrees of freedom. Background technique [0002] The refrigerator is the main device on the satellite, which is used to adjust the temperature change inside the satellite. Due to the manufacturing defects of the compressor in the refrigerator and the noise of the motor, the refrigerator produces a periodic and broadband micro-disturbance force on the star. These disturbance forces are modulated and amplified by their internal dynamic characteristics, and will affect the remote sensing satellite (GF -4) The optical path pointing accuracy and stability have a great influence. This effect is particularly important considering that the cryocooler is installed close to the imaging device. [0003] Because the disturbance of the disturbance source ...
