Control moment gyroscope vibration isolation support performance test device and test method

Abstract

The invention relates to a control moment gyroscope vibration isolation support performance testing device and method in the field of testing technical equipment. The device comprises a vibration table which is used for providing a vibration source and a vibration effect; a vibration isolation bracket which is arranged on the vibration table and is used for providing a vibration isolation effect; a control moment gyroscope simulation piece which is arranged on the vibration isolation bracket; and a suspension mechanism which is arranged above the vibration isolation support, is of a suspended ceiling structure and is used for overcoming the gravity of the control moment gyroscope simulation piece and the vibration isolation support; and acceleration sensors are arranged on the vibration table, the vibration isolation bracket and the control moment gyroscope simulation piece. The device is advantaged in that an acceleration time-domain signal can be observed in real time, the time-domain signal can be processed in real time to obtain the acceleration frequency-domain signal, the vibration isolation performance of the vibration isolation support in the three translation directions can be tested through the test method, and the test method is simple, flexible, easy to operate and high in practicability.

Description

technical field [0001] The invention relates to the field of testing technical equipment, in particular to a performance testing device and testing method for a control moment gyro vibration isolation support. Background technique [0002] With the rapid development of aerospace science and technology, high-resolution optical remote sensing satellites are playing an increasingly important role in national life and national defense. It is also an important direction for the development of satellite engineering in my country. There are more stringent requirements for temperature and micro-vibration environment. Research at home and abroad shows that the control torque gyroscope is the main factor affecting the performance index of the spaceborne payload. Therefore, it is very urgent to control and isolate the vibration interference generated by the control torque gyroscope. The suppression of such micro-vibrations is usually isolated using vibration-isolation brackets. Testin...
