Abstract: Background

The device design requirements come from high-energy synchrotron radiation sources.

Purpose

The purpose of this study was to design a new type of magnet support adjustment device that can meet the locking stability accuracy of 5 μm and the adjustment accuracy of 2 μm.

Methods

According to the actual working conditions, the modal was statically and modally analyzed in ABAQUS software. Use inventor to design support and adjustment devices that meet the accuracy requirements, including high-precision adjustment plates, high-precision ball and high-precision gaskets.

Results

The results show that the deformation of the V-frame and the adjustment plate is far less than the design requirements in statics, which can meet the adjustment requirements after installation, and the first-order natural frequency of the new device can meet the requirements of no resonance under the influence of ground pulsation.

Conclusions

The design idea and analysis results of the device satisfy the requirements of height, precision and rigidity at the beginning of the design, and lay a solid foundation for the subsequent beam center calibration and measurement.
