摘要
为提高发射效率和速度,分析了电磁弹射实验装置中电流相位的关系及决定电磁力性质的主要因素。通过改变放电电路参数及结构,获得了不同放电条件下的电流曲线,并计算出安培力的曲线,总结了影响电磁弹射实验装置中线圈相互作用力性质和作用时间、大小的主要因素,实验表明,在相同的放电条件下,振荡放电较非振荡放电磁场斥力小,作用时间短;振荡放电电路中匝数增加则电动力减少;非振荡放电电路中等效匝数变化对电动力影响不大。
A single-stage electromagnetic launcher system using pancake coil is a type of induction launcher that induces an eddy current in a metal projectile by time varying magnetic induction produced by a pancake coil. An active protection element such as armor plat or other terminal ballistics interception device can be launched by this system for the interception and disruption of an incoming round before it strike the armor of a combat vehicle. The paper analyses the relationship between electromagnetic force and phases of current in electromagnetic launch theoretically. The experiment curves of current are acquired in differential circuits. According to curves of electromagnetic force, main factors have been sum up that influence character of electromagnetic force. Experiments show that shape of power current is main factor influencing electromagnetic force.
