Numerical simulation and experiment of high-intensity current pulsed impact on structure body

To better understand the characteristics of the impulse force formed by pulse current of electromagnetic rail propulsion system, and to explore effective ways to improve the support structure of rails, a set of impulse force test system was designed, and the work-related test situation was numerically simulated. Several impulse force waveforms formed by different pulse current waveforms were achieved by using a C-shape monolithic armature as a source of impulse force in this test system, and two curves of waveform were comparatively analyzed. Numerical calculation of the armature existing in the environment of coupling fields including electric field and magnetic field and force field was carried out by ANSYS/Multiphysics, the coupling force field was emphatically analyzed to calculate the
