Optimum Design of the Support Structure of the CMG Based on CAE


Article Preview

A Control Moment Gyroscopes (CMG) is a torque generator for attitude control of a high resolution and high agility satellite without any increase in power, mass or volume. In this paper, a new support structure of the CMG is proposed. According to the configuration idea of the CMGs, the original design model of the support structure is established. Furthermore, the topology optimization is performed by the FEM software ANSYS and after that came up with a suitable layout of the support structure of the CMG. Based on the optimized design results, the 3D models of the CMG and its support structure are established by the 3D design software Pro/E. Frequency of the assembly is analyzed and calculated. Finally, took the launch dynamics environments into consideration, the vibration testing are carried out to verify the rationality of the new design structure.
