The work addresses the manufacturing of capillary tubes, involving drawing on a long movable mandrel and their subsequent reeling along the outer diameter in order to extract the mandrel, resulting in finished tubes of the desired quality. The two-stage finite element modeling (FEM) included varying key parameters such as tube reduction and clearance between the tube and the mandrel over a wide range. At the first stage, the permissible reduction was determined with a limit on the tolerance for the outer diameter. At the second stage, the occurrence of tube faceting was studied.

芯轴拉拔后毛细管卷绕过程的建模

这项工作涉及毛细管的制造，包括拉动长的可移动心轴，然后沿着外径卷绕以提取心轴，从而生产出具有所需质量的成品管。两阶段有限元建模 (FEM) 包括各种关键参数，例如大范围内的管缩径以及管与心轴之间的间隙。在第一阶段，通过外径公差的限制来确定允许的减少量。在第二阶段，研究了管刻面的发生。
