The finite element software platform ABAQUS was used to simulate the bundling and drawing process of NbTi/Cu multi-filamentary superconducting wires. The influence of drawing die parameters on the degree of core wire distortion was studied. The distortion factor is introduced to quantify the distortion of core wires,and the parameter interval corresponding to the minimum value of core wire distortion in the bundling and drawing process of NbTi/Cu multi-filamentary superconducting wires was obtained. The results show that when the semi-angle of drawing dies is6°～ 8°,the bearing length is 4. 5 ～ 5. 5 mm,and the processing rate is 20% ～ 25%,the core wire distortion of Nb Ti/Cu multi-filamentary superconducting wires has a minimum value.
