Dynamic Analysis and Testing of a Single Gimbal Control Momentum Gyroscope

Abstract

Control Momentum Gyroscope (CMG), are the most complex moment control devices, capable of producing on the spacecraft torques obtained by combining two movements: one similar to that performed in the case of Momentum Wheels MW (a rotation of an inertial mass around an axis) with one axis of rotation perpendicular to the axis of inertial mass, this second axis being called the gyroscopic axis. The paper presents design of a Single Gimbal Control Moment Gyroscope (SGCMG) and mathematical model of dynamic analysis for a Single SGCMG. Based on the mathematical model it has been performed simulations of SGCMG using SolidWorks Simulation Premium (Motion Analysis). The results from the simulations are compared with tests performed on a testing stand for SGCMG developed at ICPE-CA.
