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,对电磁飞板发射物理过程进行了理论分析,建立飞板发射阶段的运动模型,得到飞板发射阶段的运动特性规律,并对发射线圈的结构进行了初步优化。研究结果表明:发射线圈的特性参数对于飞板速度的影响较为明显,减小整个回路自感,增加互感,可以有效提高飞板速度,而飞板的加速度总体呈现线性特征。研究结果在军事、宇航等具有较大的应用价值。

Based on physical processes and variation principle of mutual inductance between flying plate and transmitter coil in the process of electromagnetic launch, the electromagnetic flying plate's motion model in the launch phase was established. Based on this model, the electromagnetic flying plate's motion characteristic law was studied, and the transmitter coil's structure was optimized. The results show that the transmitter coil parameters have obvious impact on the velocity of flying plate, the inductance in the loop is reduced, and the mutual inductance is improved so as to improve the speed of flying plate, the flying plate shows linear acceleration. The research result will be widely applied to military and aerospace.
