Collaborative Simulation and Testing of the Superconducting Dipole Prototype Magnet for the FAIR Project

【摘要】 The superconducting dipole prototype magnet of the collector ring for the Facility for Antiproton and Ion Research (FAIR) is an international cooperation project.The collaborative simulation and testing of the developed prototype magnet is presented in this paper.To evaluate the mechanical strength of the coil case during quench,a 3-dimensional (3D) electromagnetic (EM) model was developed based on the solid97 magnetic vector element in the ANSYS commercial software,which includes the air region,coil and yoke.EM analysis was carried out with a peak operating current at 278 A.Then,the solid97 element was transferred into the solid185 element,the coupled analysis was switched from electromagnetic to structural,and the finite element model for the coil case and glass-fiber reinforced composite (G10) spacers was established by the ANSYS Parametric Design Language based on the 3D model from the CATIA V5 software.However,to simulate the friction characteristics inside the coil case,the conta173 surface-to-surface contact element was established.The results for the coil case and G10 spacers show that they are safe and have sufficient strength,on the basis of testing in discharge and quench scenarios.更多还原
