Nb_(3)Sn超导磁体运行时产生很高磁场,Nb_(3)Sn超导线圈会受到很强电磁体力的作用,从而会产生很大的力学应变.由于Nb_(3)Sn超导材料的应变敏感性,会使得Nb_(3)Sn磁体线圈的临界性能退化,这对磁体的安全稳定运行造成极大影响,所以精确计算超导磁体在电磁体力下的力学行为具有重要的科学意义.Nb_(3)Sn超导磁体主要是由超导线绕制成线圈结构再经过环氧树脂固化而成,Nb_(3)Sn超导线是主要由多根微米级的超导芯丝、铜形成的复合结构,所以从超导芯丝到超导磁体其尺寸跨越了几个数量级,从而给精确分析超导线圈力学变形带来挑战.本文首先采用代表性单元均质化方法分析了整体线圈的等效力学参数,通过对比等效均质化模型与线圈真实结构的计算结果,发现等效均质化模型存在很大的误差.因此,提出一种高精度而且计算代价低的双向均质化分析方法,研究超导线圈内各组分材料(Nb_(3)Sn芯丝、铜和环氧树脂)应力-应变分布.该方法不需要进行大规模的数值建模,并且与真实复合线圈下的结果对比吻合很好,由此验证了该方法的有效性和准确性.最后基于提出的双向均质化分析方法,详细讨论了Nb_(3)Sn超导线圈各层材料在电磁力作用下应力-应变随匝数和层数的变化规律.
