Embodiment Construction

[0028] There are many methods for state monitoring and fault diagnosis of rotating parts, including vibration acoustic method, speed change method, acoustic emission method, current analysis method, temperature method, pressure pulsation method, etc. Among them, vibration diagnosis technology shows simple and reliable advantages in signal acquisition, data processing, fault identification and diagnosis of the diagnosed system, especially suitable for non-stop online monitoring and diagnosis and alarm. Therefore, vibration analysis technology has become the most commonly used diagnostic method, which can analyze the normality, abnormality or defects from the vibration information of the test moving parts in the specified action process.

[0029] In the condition monitoring process of satellite rotating parts, it is necessary to give a proper evaluation of the quality status of the product, which involves the issue of judging criteria. If the standard is set too high, it will ca...

Abstract

The invention discloses a state monitoring and diagnosis alarm method for a mechanical component of satellite borne rotary equipment, which comprises the following steps of: detecting a process of recording vibratory response of a satellite borne rotary mechanism; reading acceleration response measurement time domain signals; analyzing an acceleration response measurement spectrum; setting an emergency alarm or shutdown line; setting an early warning line in a time domain 0.25g and a frequency domain 0.5 multiplication (0.03g); presetting an amplitude alarm line 0.25g in software of data time domain acquisition, and sending early warning prompt when reaching or exceeding the value; and likewise, setting an early warning value in the frequency domain at 0.5 frequency multiplication such as fast scanning 100Hz or 300Hz. The method solves the problems of evaluating the state of the mechanical component of the rotary equipment of a satellite and predicting and assessing the performance variation tendency and the life limit of the mechanical component and the like. The method is simple, convenient and effective to implement, prolongs the service life of the satellite borne rotary equipment, and improves the work efficiency and the like.

Description

technical field [0001] The invention relates to a method for state monitoring, diagnosis and alarm of mechanical parts of satellite-borne rotating equipment. Background technique [0002] The mechanical parts of spaceborne rotating equipment, such as the second scanning mechanism of the satellite scanning radiometer, are composed of gear boxes, potentiometers, gears, screws, nuts, bellows, stepping motors and other parts. The design adopts the movement mode of changing from rotation to translation, and then from translation to swing. Specifically, the stepping motor drives the sliding screw pair through the gear reducer to make the guide frame fixedly connected with the nut move in translation, and then use a set of steel belt fan-shaped The body transmission mechanism makes the folding mirror fixedly connected with the sector body swing around the X axis ±5°. [0003] The second sweep screw pair is a small-pitch precision sliding screw pair structure. The normal scanning f...
