Abstract 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.

Key words： Electromagnetic forming solenoid coil suppressing temperature rise structure optimization
