| Abstract: | According to the Maxwell equations,the launching process of C-shaped solid armatures is studied. A static model for E ML is discussed to simulate the three dimension C-shaped armature. In this paper,the solid three-dimensional finite element model of a C-shaped armature is established by ANSYS analytical software. Several kinds of improved C-shaped armature are simulated and the results show the distributions of the magnetic induction intensity,the current density and the temperature. Analysis of its geometric structures influence on the electromagnetic properties is made. The research results can provide the basic theoretical foundations for the armature design and lessen erosion in armature. |
