摘　　要：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.根据已失效匀压力线圈的结构参数,分析板料、线圈、外部通道的电流和磁场力分布。结果表明:基于模拟结果的电流方向与匀压力线圈的工作原理一致。提出匀压力线圈失效的原因。然后将板料上的磁场力作为边界条件输入显式分析软件ANSYS/LS-DYNA,分析板料的变形规律。
