Structure improved design and intensity experiment on drive coil

Abstract

To sustain the strength of electromagnetic force, according to the stress distribution of a drive coil, the prime design requirements of the drive coil are presented, the drive coil is designed and manufactured, and intensity damage experiments are carried out. The experiments indicate that the heat and joint effect of electromagnetic forces is the major cause of drive coil damage, and interturn insulation damage is the main damage mode. Based on this foundation, two methods are presented to reinforce the density of the drive coil; in the first method, the material of the reinforced structure of the drive coil shifts from nylon to steel; in the second method, the drive coil cooling system and temperature control systems are presented. The relationship between flow velocity in the cooling system and temperature rise is determined based on the flow-solid coupled theory, and temperature distribution of the drive coil is analyzed in different flow velocities. The experimental testing of the drive coil cooling system is made. Finally, the design manufacturing of the drive coil and epoxy filling is described in detail, which is the engineering foundation for the coil launcher.
