Force Analysis of Upper and Lower Coaxial Combined Coils for Attractive Electromagnetic Forming
摘要
Abstract
Electromagnetic forming is a kind of high-speed forming technology,which uses coils to generate pulse electromagnetic force to drive metal deformation.,the coils also bear huge magnetic stress.Especially with the improvement of discharge parameters and the use of combined coils,multiple coils have magnetic coupling in space and sequential control in circuit,which greatly increases the risk of stress damage.Therefore,this paper analyzes the stress state and failure condition of the combined coil under high parameters by experiment and simulation.The results show that the stress state of the combined coil is more complicated and extreme,and the coupling of the coil worsens the stress in local areas,and the axial reinforcement material breaks at a lower discharge voltage than the radial one.At the same time,the combined coil should be fully stress-checked during design.关键词
