The fourth generation light source has more strict requirements on spot stability and resolution. This paper introduces a new type of crystal attitude adjustment module, including the Angle adjustment mechanism and the roll Angle adjustment mechanism. In order to improve its stability, the flexible hinge with poor stiffness was optimized, and the auxiliary support hinge design was innovatively proposed to bear the axial load weight and increase the overall rigidity, and the stiffness of the mechanism was improved without increasing the driving force. Through the simulation calculation, the overall mode of the new crystal attitude adjustment module is 234Hz, the maximum stroke of the casting Angle is ±0.5°, and the maximum thrust required is only 40.0N. As the distance between the motor and the rotating center is increased, the resolution is also improved when the same driving motor is used. The new crystal attitude control module offers significant improvements in both stability and resolution. PB - JACoW Publishing CP - Geneva, Switzerland ER -
