摘　　要：电磁成形过程中线圈温升过高会缩短其使用寿命,优化线圈结构可以在不影响成形效果的情况下降低温升。该文以管件电磁成形所使用的螺线管线圈为研究对象,利用电磁场—机械结构场—温度场耦合有限元模型,针对线圈绕制工艺的特点,详细探讨线圈层数、匝数、高度、宽度、匝间距以及层间距这六种结构参数对线圈温升及成形效果的影响。仿真结果表明,合适的结构参数均能抑制线圈温升,同时保持工件成形效果,但六种结构参数的影响程度并不相同。该结果为管件电磁成形线圈的结构优化设计提供了建议,为提高线圈使用寿命指明了方向。In the electromagnetic forming process,high temperature rise of the coil will shorten its service life.Optimizing the coil structure can reduce the temperature rise without affecting the forming effect.In this paper,the solenoid coil used in the tube electromagnetic forming is taken as the research object.Based on the electromagnetic field-mechanical structure field-temperature field coupling finite element model,according to the characteristics of coil winding process,the influence of six structural parameters of coil layer number,turn number,height,width,turn spacing and layer spacing on the coil temperature rise and forming effect is discussed in detail.The simulation results show that suitable structural parameters can reduce the temperature rise of the coil while maintaining the forming effect of the workpiece,but the influence of the six structural parameters is not the same.This paper provides suggestions for the structural optimization design of the tube electromagnetic forming coil,and clarifies the direction for improving the service life of the coils.
