Analysis of the magnetomechanical coupled effect on electromagnetic propulsion

The magnetomechanical coupled effect on electromagnetic propulsion is an important topic in related fields. However, the high dynamic electrical contact between rails and the armature leads to mesh deformation in finite element simulations, which markedly increases the difficulty of describing the coupling effect. In contrast, the experimental method that uses a calibrated sensor is more reliable than the finite element method. Thus, this paper used the ordered coupling method to study the magneto-mechanical coupling relationship of an armature from both static dynamic perspectives. A multiparameter projectile-borne storage testing system was also developed and calibrated. To describe the synchronous collection and recovery of different physical field parameters, a variety of sensors were used to measure the magnetic induction and the velocity of the armature. The test results show that the change in magnetic induction at the launch load can be used to judge the movement state of the armature when the correction factor is introduced.
