Circuit simulation of the electromagnetic railgun system

Based on the principle of electromagnetic railgun launch, a circuit model was developed and validated, the pulse forming units (PFU) and the progress of the railgun launch were included. The corresponding Pspice circuit code was developed to simulate the current of each pulse forming unit. Acceleration properties of the armature were also simulated by the Pspice analog behavioral modeling tools. The simulated railgun current and the armature velocity were 2.6% and 9.8% higher than the experiment results, i.e., the simulation and the experiment results were roughly consistent with each other. The model has provided valuable data which can directly benefit the design and operation of the series augmented railgun systems.
