Abstract

A three-degree-of-freedom two-body satellite vibration isolation ground test system is provided. A load platform simulator and a service platform simulator are located in the middle of an air floating platform. A visual measurement system is arranged on the upper part of the load platform simulator and the service platform simulator. A plane mirror 1 is fixed on the air floating platform on a side of the load platform simulator side. A plane mirror 2 is fixed on the air floating platform on a side of the service platform simulator. A ground console is arranged on a side of the air floating platform. A vibration isolation device is installed at a position between the two simulators. The test system uses the non-contact vibration isolation device to divide a traditional satellite into two parts which are a load module and a service module, thereby realizing the mechanical decoupling of the two modules, and cutting off the transmission of the vibration. The test system can provide a working environment with ultra-high precision and stability for a sensor carried by the load module, avoids the interference of the vibration of the satellite components and has a high application value to the future ultra-high precision sensor.

Description

technical field [0001] The invention relates to a three-degree-of-freedom double-body satellite vibration-isolation ground test system, which belongs to the technical field of double-body satellite vibration-isolation ground test systems. Background technique [0002] Space telescopes and high-precision communication satellites operating in orbit have very high requirements for pointing accuracy. Sensors working on such satellites need to provide an environment with high pointing accuracy and stability. However, in addition to the interference of the space environment on the orbiting satellite, according to the current technology, the most direct impact on the accuracy of the sensor is the interference of the vibration of some operating instruments on the satellite, such as flywheels, gyroscopes, and propellers. A series of vibrations etc. [0003] At present, the vibration isolation technology adopted mainly includes passive vibration isolation technology, semi-active vib...
