基于电路与动力过程耦合作用的方法和发射过程中发射线圈与飞板的互感变化原理，对电磁飞板发射过程进行了理论分析。利用电、磁能量转换，牛顿定律和虚位移原理，建立了飞板发射阶段的运动模型，推演出飞板发射阶段的运动特性规律。通过试验研究了电磁驱动飞板的发射过程，证明了理论模型的准确性。研究结果表明，减小发射线圈回路自感，增加互感，可以有效提高飞板的速度。

The method of coupling effect of circuit and dynamic process was applied as well as the variation principle of mutual inductance between flying plate and transmitter coil in the process of the electromagnetic launch,and the launch process of electromagnetic flying plate(EFP)was theo-retically analyzed.The motion model of EFP in the launch phase was established by using the e-lectromagnetic energy-conversion,Newton’s law and virtual placement principle.The launch law of EFP motion characteristics was studied.The launch process of EFP was studied by experiment,and the accuracy of the theoretic model was verified.The results show that the speed of the flying plate can be improved effectively by reducing the inductance in the loop and improving the mutual inductance.
