摘要: 以系统能量转换效率为目标函数,建立了单级脉冲感应线圈炮的数学模型,对电枢初始位置、电容器组放电电压和电容量进行了优化分析,获得了三者影响能量转换效率的规律。分析结果表明,要提高系统能量转换效率,弹丸穿越驱动线圈时加速行程的时间应当与驱动线圈中电流的上升时间相匹配,通常情况下电容器组采用高电压、小电容量的配置方式,系统可获得较大的能量转换效率。Abstract: In order to gain the rule between them, the mathematic model of single stage pulse induction coilguns is built, and the launch process is simulated and analyzed. The electrical-to-kinetic energy conversion efficiency of system is regarded as a target function, and the initial position of the armature, the discharge voltage and the capacitance of capacitor banks are regarded as variables. Results of analysis indicate that the time of projectile to be accelerated in the drive-coil should match the time of current rising in the drive-coil. As a rule, the high energy conversion efficiency can be gained in the system with capacitor banks of high voltage and low capacitance.
