[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.
