AbstractThis paper mainly introduces the motion analysis and the stress of some components of the full-disc vector magnetograph (FMG). As the connecting part of the FMG and the satellite platform, its main function is to adjust the optical axis of the FMG so that its imaging of the sun remains in the center of the CCD, thus achieving pitch and yaw of the optical axis. The maximum adjusting range is ±12′ and the regulation precision is ±5′′. The kinematic support is used to connect the optical box and the satellite platform. The two Monopods are respectively mounted on the two YZ planes of the optical cabin. The Bipod is mounted on the XZ plane of the optical capsule, which can adjust the pitch and yaw of the optical capsule. The movement of the Bipod is mainly powered by two motors. This paper simulates the force condition of the motor's screw sleeve to calculate the parameters of the motor. This article simulates the upward, downward, leftward and rightward movements of the pitch and yaw motions of the FMG's on-orbit pointing adjustment mechanism. Compared with the results of MATLAB theoretical calculations, the maximum error of the simulation results is 0.7969mm, and the minimum error is 0.0212mm, which basically accords with the ideal sports condition. © 2019 SPIE.
