Abstract

Abstract: The slip ring used to conduct electric signal for rotor is an important component of 200N·m·s control moment gyro (CMG). It is necessary to carry out the life test of the electric ring, because it determines the life of 200N·m·s CMG. The life test of conductive slip ring is presented in this paper. Purpose and object of the test, acceleration factor, test environment, test system configuration and failure criterion are described in detail. Electric noise, frictional torque and insulation performance are analyzed during the test, and the results show the performance of the conductive slip ring satisfies the need for 200N·m·s CMG after 4 million turns of test.

Key words: CMG, conductive slip ring, life test
