FAIR工程中CR二极超导磁体样机的结构分析

Structural analysis of CR superconducting dipole magnet in FAIR project

介绍了德国FAIR(The Facility for Antiproton and Ion Research)工程中收集环CR(Collector Ring)二极超导磁体的结构设计;用CATIA软件建立了CR二极超导磁体的三维模型,并用有限元分析软件ANSYS对建立的模型进行了磁场和电磁力的分析;基于磁场分析对线圈盒进行了位移和应力的分析;对磁体失超后液氦容器可能出现的最大位移和最大应力进行了分析,为正式磁体的制造提供了必要的参数。

The engineering design of Collector Ring（CR） superconducting magnet of German FAIR（ the Facility for Antiproton and Ion Research） project was introduced; 3D model of the magnet was made by CATIA, then the magnetic filed of 1/4 magnet model was analysed with ANSYS. The displacement and stress of the coil case were analysed based on the analysis of magnetic field. The maximal displacement and maximal stress of the liquid helium case were analysed when quenching happens. The results of analysis and research are necessary parameters for manufacturing the experimental magnet.
