【摘要】：根据用户的实验要求为实现在上海光源中产生低轴功率密度的同步辐射光设计了新型波荡器EPU200。EPU200是首台拥有八排磁化块，可以产生椭圆极化辐射并降低轴功率密度的纯永磁波荡器。其八排磁排列安装在四根铝梁上，每个磁化块固定件上安装两块磁化块，其磁结构的机械结构和安装十分复杂。而磁结构对波荡器的品质有很大影响。所以需要对其磁结构进行力学分析和研究。本文首先介绍了同步辐射光源及波荡器磁结构的发展、低轴功率密度波荡器的发展现状、磁结构的机械设计和新型波荡器EPU200设计的背景；其次介绍了常用的力学分析方法和有限元方法的基本原理，并对Ansys Workbench软件进行简要介绍；接着详细描述了EPU200的磁排列和机械结构；简要介绍磁场计算软件RADIA并计算出不同状态下EPU200中磁化块的最大受力；然后通过有限元分析软件对磁结构的关键零件及整体进行力学分析，计算出磁结构的最大变形和最大应力，并对不同状态下的磁结构的变形和应力进行分析比较，从而确定方案的可行性；最后加工并安装试验件验证磁结构的稳定性。 EPU200磁结构的力学分析结果和试验件的成功安装验证了该结构的可行性和稳定性，为EPU200磁结构的加工安装提供依据，具有很强的实用价值和工程意义。
[Abstract]:According to the user's experimental requirements, a new type of wave swing device (EPU200.EPU200) is designed for the realization of synchrotron radiation light with low axial power density in Shanghai light source. It is the first one with eight rows of magnetized blocks. A pure permanent magnet waver that generates elliptical polarization radiation and reduces the axial power density. The eight rows of magnets are arranged on four aluminum beams and two magnetized blocks are installed on each fixed piece. The mechanical structure and installation of the magnetic structure are very complicated. The magnetic structure has a great influence on the quality of the waver. Therefore, it is necessary to carry out mechanical analysis and research on its magnetic structure. In this paper, the development of synchrotron radiation light source and waver magnetic structure, the development status of low axis power density waver, the mechanical design of magnetic structure and the background of EPU200 design of new type waver are introduced in this paper. Secondly, the basic principles of mechanical analysis and finite element method are introduced, and the Ansys Workbench software is briefly introduced, and then the magnetic arrangement and mechanical structure of EPU200 are described in detail. This paper briefly introduces the magnetic field calculation software RADIA and calculates the maximum force of the magnetized block in EPU200 under different states, and then carries out the mechanical analysis of the key parts and the whole of the magnetic structure by the finite element analysis software. The maximum deformation and maximum stress of the magnetic structure are calculated, and the deformation and stress of the magnetic structure in different states are analyzed and compared to determine the feasibility of the scheme. Finally, the stability of the magnetic structure is verified by machining and installing the test piece. The results of mechanical analysis of EPU200 magnetic structure and the successful installation of the test piece verify the feasibility and stability of the structure, and provide the basis for the processing and installation of the EPU200 magnetic structure, which is of great practical value and engineering significance.
