The static deformation and adjustment precision of the storage ring's mechanical support determine the positioning accuracy of each physical component. The dynamic response characteristics of these components affect the stability of the beam current. Therefore, mechanical support serves as the installation foundation for all physical components, ensuring the correct installation and operation of magnets, vacuum chambers, beam diagnostics, and other elements, thereby enabling them to exhibit their corresponding physical performance. Therefore, designing mechanical support with high stability holds extraordinary significance. Taking the Shenzhen Innovation Light source Facility (SILF) as an example, this article utilizes SolidWorks and Ansys software to design and optimize the magnets support of the storage ring. The process of mechanical support design and optimization simulation for the storage ring is elaborated in detail. The final design is assembled with the magnet model, and the overall support is simulated and validated as closely as possible to the real operating conditions to ensure compliance with the parameter requirements of the physical design.
