Torque test air support rotating platform for control torque gyro

Abstract

The invention relates to control moment gyro using moment testing gas floating rotate table that includes air hydrostatic bearing, main shaft encoder, workbench and torquer. The main shaft encoder is used to testing the angle location; the workbench is used to install testing object and the torguer is installed on the bottom of the air hydrostatic bearing to drive main shafting. The pressure of air hydrostatic bearing would be adjusted by pressure adjustor. The invention has the advantages of low attrition disturbance, easy to operate, convenience and high accuracy.

Description

Technical field [0001] The invention relates to a torque test air-floating turntable for a control moment gyroscope, which can be used as a high-precision test equipment for the output torque and torque resolution of the control-moment gyroscope, and can also be used as a high-precision test equipment for the output torque of a momentum wheel and a reaction flywheel. Background technique [0002] With the development of space technology, space stations, large-scale observation satellites and other spacecraft have become an important part of the space strategy of all countries in the world. Because the output torque of the momentum wheel and the reaction flywheel is usually only within 1Nm, and as the output torque increases, the power demand is also Higher, and Control Moment Gyroscope (CMG) can effectively solve the above problems, so it has received extensive attention and research from all over the world. CMG is a key actuator for long-term operation of large spacecraft (inclu...

AI Technical Summary

Problems solved by technology

CMG is the key actuator for attitude control of long-running large spacecraft such as space stations (including small spacecraft such as sensitive satellites), and the output torque, control accuracy and torque resolution of CMG directly affect the overall performance of the spacecraft. , that is, the performance of CMG must be accurately measured, so the test equipment for the comprehensive performance of CMG is particularly important, but there are no test equipment and instruments for the comprehensive performance of CMG at home and abroad.
