A lumped parameter model of capacitor-based railgun (CBRG) with arbitrary number of pulse-forming units is created and design of its simulation code is introduced. To show simulation and optimization capabilities of the code, two applications of the code are given. In the first example, a CBRG with topologically created pulse-forming network is simulated and the results are analyzed to show the availability...
The pulse-width modulated valve (PMV) plays an important role in the whole electro-hydraulic automatic control system. In this paper, the magnetic field of the axially symmetric plane model simplified of the PMV is simulated with the magnetic finite element, thus accurate results on the distribution of magnetic field and flux-line can be obtained, as well as variation of the magnetic force and inductance...
