结合淬火模拟程序和ANSYS程序，研究了环氧浸渍Nb/sub 3/Sn高场磁体内部因淬火而产生的热变形和机械应力。我们使用高场余弦型偶极磁铁的几何形状，长度分别为1米和10米。淬火开始的匝被过度加热，最高可达100k至300k，这取决于线圈长度和延时。非淬火匝和周围材料基本上不加热。这种大的温度梯度导致淬火导体及其绝缘材料中的高局部应力。利用ANSYS程序对该响应进行了计算。
Thermal deformation and resulting mechanical stress due to quenches inside epoxy-impregnated Nb/sub 3/Sn high field magnets are studied with a combination of a quench simulation program, and the ANSYS program. We use the geometry of the high field cosine theta type dipole magnets with one meter and 10 meter length. The turns where quenches start are heated excessively, up to 100 K to 300 K, depending on the coil length and time delay. The non-quenching turns and surrounding material are not heated substantially. This large temperature gradient causes high local stress in the quenching conductors and their insulation material. The ANSYS program is used to calculate this response.
