摘要
中国科学院高能物理所高场超导团队提出了一种环形超导动能加载方案。本文针对其核心转子REBCO高温超导线圈,通过建立三维电磁-热-力耦合模型,进行了7 650 rpm和15 300 rpm时系统的应力分析,涵盖冷却、励磁及旋转过程。此外,还探讨了加电方式对线圈应力的影响。结果表明:转速提升时多匝线圈应力增加更显著。在低转速时线圈的环向应力呈沿径向递增的压应力状态;而在高转速时,转变为沿径向递减的拉应力。同步加电方式能有效降低线圈的应力。
The high field superconducting team of the Institute of IHEP CAS proposed a circular superconducting kinetic en-ergy loading scheme.In this paper,the stress analysis of the core rotor REBCO high temperature superconducting coil at 7650 rpm and 15300 rpm was carried out by establishing a three-dimensional electromagnetic-thermal-mechanical coupling mod-el,covering the cooling,excitation and rotation processes.In addition,the influence of power-on modes on coil stress was also discussed.The analysis results show that the stress of multi-turn coil increases more significantly when the speed increases.At low speed,the hoop stress of the coil is in a radially increasing compressive stress state.At high rotational speed,it is trans-formed into tensile stress decreasing along the radial direction.Synchronous power-on mode can effectively reduce the stress of the coil.
