Analysis of in-Bore Magnetic Field for Railguns at Zero Speed

摘要：

　　A two-dimensional transient computational model was built in this paper to analyse the in-bore magnetic field. The current density in the rails and armature had been calculated by solving the reduced magnetic-diffusion equation. Through the calculated current density and the Biot and Savarts law, the in-bore magnetic field had been calculated. The results show the concentration of current occurs at the left-hand edge of the rail– armature interface initially, then the current spread to the internal conductor within 1ms. The field point which closer to the origin coordinate has higher value of magneitc flux density.
