Magnetic force distribution and deformation law of sheet using uniform pressure electromagnetic actuator

Abstract The distribution of magnetic forces and current on sheet and coil was analyzed in detail according to the structural parameter of the coil which was invalid. The result shows that the current direction based on simulation result agrees with the principles of uniform pressure electromagnetic actuator. The reason for coil failure was proposed. Then the magnetic forces on the sheet were input into an explicit finite element software ANSYS/LS-DYNA to analyze the deformation law of the sheet.
