股间力关系到超导股线在大电磁力作用下的力学响应，对ITER磁体结构的安全性具有重要意义。Zhu等人（2012，Supercond. Sci.技术人员：25，125011）。在这里，我们报告的接触力的直接测量的二维系统内的光弹性盘受到单向压缩，并获得的接触力（包括力链）和它的方向。然后，我们可以得出结论，股之间的接触力分布是强各向异性。我们使用概率密度函数来分析这种不均匀性。氦气通道对接触力行为的影响也被考虑在内。值得注意的是，在此压缩过程中的能量损失也计算基于实验结果，这被认为是适合于提供电磁力下的超导股线之间的接触力行为的定性预测。
Interstrand force is related to the understanding of the mechanical response of superconducting strand under large electromagnetic force, which is important to the safety of the ITER magnet structure. A two-dimensional discrete element method and relevant simulations to quantitatively characterize the contact force behavior on the superconducting strands in the ITER cable-in-conduit-conductor cross-section has been performed by Zhu et al. (2012, Supercond. Sci. Technol., 25, 125011). Here, we report direct measurements of the contact forces inside a two-dimensional system of photoelastic disks that are subjected to a single-direction compression, and obtained the contact force (including force chain) and its direction. Then, we can conclude that the contact force distribution among strands is strongly anisotropic. We use a probability density function to analyze this inhomogeneity. The influences of a helium channel on the contact force behavior are also taken into account. Notably, the energy loss during this compression is also calculated based on the experimental results, which are considered to be suitable for providing qualitative predictions of the contact force behavior among the superconducting strands under electromagnetic force.
