Abstract:Based on Maxwell equation, a time stepping finite element analysis(FEA) model coupled circuit field and movement used in analyzing single-stage inductive coil gun is presented in this paper, which could solve the problem of impulsing power supply in field-circuit coupled FEA. The transient 2D magnetic field circuit coupling problems are solved by the Crank-Nicholson method, and the problems of motion is handled by the moving coordinates. The force is calculated by nodal force method. The paper sets up the 2D transient electromagnetic field-circuit-moving model of single-stage inductive coil gun. The performance of a single-stage inductive coil gun is analyzed using above model. The calculation result is very close to the measure results, which verifies the model accuracy.
