摘要: 储存环机械支撑的静力变形、调节精度决定各物理元件的定位精度，其动态响应特性间接影响着束流的稳定性，机械支撑是各物理元件的安装基础，保证磁铁、真空室、束测元件正确的安装、运行，发挥出相应的物理性能。主要从支撑的静力变形和固有频率两个方面对机械支撑进行优化设计。以深圳产业光源（SILF）共架支撑为例，利用SolidWorks和Ansys软件对储存环磁铁机械支撑进行设计、拓扑优化。详细阐述了储存环机械支撑设计、优化的过程，并将最终优化完成的支撑模型与磁铁模型进行装配，在尽量接近真实工况的基础上对整体支撑进行仿真计算，以确保支撑整体能够达到设计指标。Abstract: 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.
