Parametric effect of large impulse current ezcited coil on electromagnetic force in coil-sheet system

摘要：

Based on the method of controlling welding stress with trailing, the electromagnetic force in coilsheet system was simulated with finite element software ANSYS. The effect of parameters of coil on the electromagnetic force density fy, was analyzed. The results show that the maximum electromagnetic force density fy,max in sheet appears in the position near the inner radius of single-turn coil. The position is independent of section shape of coil. fy, max for flat coil is larger than that for long coil and the coil with wedge shape section, while section areas of all coils are equal to each other. The effect of turn number of multiple-turn coil on fy is dependent on the loop resistance in circuit. The kind of coil with more turns and larger inductance is commended while there is larger loop resistance in circuit.fy increases in a certain magnitude while a magnetic core is located in coil. However, the magnitude of fy is limited by saturating magnetic flux of the core.
