摘要 重接炮是一种利用磁力线重接来推动发射体的电磁炮,发射体受力正比于电感梯度与回路电流平方的乘积。基于重接式电磁发射电路方程和运动方程,并结合发射装置的实测参数,建立了发射体运动过程的数值仿真模型。针对多级发射中由于发射体速度过快而造成加速不充分和发射效率下降的问题,提出了多级发射的优化物理设计原则,该原则按照发射体速度确定各级回路电流的振荡周期,继而确定各级电容器组的电容值和初始电压值,配合使用触发真空开关(TVS)作闭合开关,利用其特有熄弧性能,可以显著提高发射体速度和发射效率。 Reconnection gun is a form of electromagnetic gun that utilizes the magnetic field line reconnection to accelerate a projectile. The force on the projectile is proportional to the product of the inductance gradient and the square of the circuit current. Combined with the data measured from the launch apparatus, the numerical simulation model of the projectile motion course was established on the basis of the circuit equation and the motion equation of the reconnection electromagnetic launch. To solve the problem of insufficient acceleration and launch efficiency decrease resulting from the projectile hypervelocity, an optimized physical design principle for the multi-stage launch was presented. The projectile velocity and the launch efficiency can be greatly improved by the above principle, with which the oscillating cycle of the circuit current in every stage and the capacitance and the initial voltage of the capacitor bank are determined according to the projectile velocity, and adopting the triggered vacuum switch (TVS) as the closing switch which has special arc extinguishing performance.
