本文给出了超导磁体应力分析的解析解，它反映了洛伦兹体力的空间全变化，并包括剪应力分量。该解决方案是基于幂级数展开的洛伦兹体力和位移，这反过来又给出了应变和应力，包括剪切应力分量。该解决方案适用于磁体的绕组和加强层，并与使用具有加强件的7 T样品磁体的有限元方法进行比较。
An analytical solution for the stress analysis of superconducting solenoids is given which reflects the full spatial variation of Lorentz body forces and includes shear stress components. The solution is based on power series expansions of the Lorentz body forces and the displacements which in turn gives the strains and stresses, including shear stress components. This solution is applicable to the windings and reinforcement layers of magnets and is compared to a finite element method using a 7 T sample magnet with reinforcement.
