摘要

针对传统管件电磁胀形存在管件壁厚减薄严重和变形不均匀等问题,本文提出基于双层凹型集磁器结构的单线圈管件电磁成形方法,通过径向电磁力场分布的调控和轴向电磁力的协同加载,为同时抑制管件减薄和改善变形均匀性提供了新的技术途径。为验证该方法的有效性,基于电磁-结构场耦合数值模型,对比探究了有无双层凹型集磁器下轴径电磁力分布特性、管件壁厚减薄量以及轴向变形均匀性等关键物理量的变化规律,并研究了集磁器的内凹高度对管件成形行为的影响。仿真结果表明,与传统管件电磁胀形方法相比,新方法下管件壁厚减薄量可从22.07%降低至8.30%,且轴向均匀性提高2.31倍。

Abstract：

Aiming at the problems of serious thinning and uneven deformation of traditional tube electromagnetic bulging, this paper proposes a single-coil electromagnetic tube forming method with a double-layer concave magnetic field shaper. Through the regulation of radial electromagnetic force field distribution and the synergistic loading of axial electromagnetic force, it provides a new technical way to simultaneously suppress tube thinning and improve deformation uniformity. In order to verify the effectiveness of the method, based on the electromagnetic-structural field coupling numerical model, the variation of key physical quantities including the distribution characteristics of the axial-radial electromagnetic force, the wall thickness reduction of the tube and the uniformity of the axial deformation in the presence or absence of the double-layer concave magnetic field shaper are compared and explored. Meanwhile the influence of the concave height of the magnetic field shaper on the forming behavior of the tube is investigated. The simulation results show that compared with the traditional tube electromagnetic bulging method, the wall thickness reduction of the new method can be reduced from 22.07 % to 8.30 %, and the axial uniformity is increased by 2.31 times.
