摘　　要：基于RLC电路及飞板与发射线圈间的互感变化原理,对电磁飞板发射的运动过程进行了理论分析,建立了飞板的运动模型,并通过电磁飞板发射的试验研究验证了理论模型的正确性。利用理论分析得出影响速度的主要因素为线圈自感、线圈电阻、线圈与飞板之间的互感。依据飞板运动模型分析了线圈结构参数对飞板速度的影响,为线圈结构优化设计提供了理论依据。利用Maxwell 2D对飞板发射过程进行仿真计算,并与理论结果对比。结果表明:减小线圈匝数,增大线圈径向宽度,增加线圈高度并减小线圈间距均有利于提高飞板的最终速度。According to RLC circuit and principle of mutual inductance between the flying plate and transmitter coil, the move ment of flying plate through was analyzed theoretically, and the flying plate motion model was established and verified Based on experimental trials. Theoretical analysis indicated that the flying plate was mainly affected by coil self-induction, coil resistance, and mutual inductance. Based on the motion model, the effect of structural parameters on the speed of flying plate was analyzed, which provided an optimization design of coil structure. Launching process of flying plate was simulated using Maxwell 2D and compared with the results of theoretical analysis. Results show that, speed of flying plate can be improved by reducing turns per coil, increasing radial width and height of coil, and reducing spacing of coil.
