为了使同步感应线圈炮获得较大的出口速度和较高的能量转化效率,对同步感应线圈炮固有的电枢减速特性进行了分析研究。从集总参数模型推导并分析了电枢减速特性产生的原因,采用场路耦合的方式进行了定量的仿真计算。根据分析结果,从驱动线圈和电枢线圈之间磁场耦合的角度提出了减小电枢减速特性的方法,并进行了有限元仿真分析。结果表明,改变电源参数如提高电容初始电压或者增加电容值,改变电枢参数如减小电枢质量、采用绕线式电枢,都可有效减小电枢减速特性,提高系统效率。搭建4级线圈炮发射系统进行了实验,对比仿真和实验结果表明,改变电枢参数减小电枢减速特性符合实际需求。结论可供同步感应线圈炮的设计参考。
In order to make the synchronous induction coil gun obtain larger exit velocity and higher energy conversion efficiency, the inherent armature deceleration characteristics of the synchronous induction coil gun are analyzed and studied. The causes of the armature deceleration characteristics are deduced and analyzed from the lumped parameter model. Quantitative simulation is carried out by the way of field-circuit coupling. According to the analysis results, a method of reducing the armature deceleration characteristic is put forward from the perspective of the magnetic field coupling between the driving coil and the armature coil, and the finite element simulation analysis is carried out. The results show that changing the power parameters such as increasing the initial voltage of capacitor or increasing the capacitance value, changing the armature parameters such as reducing the armature mass and using the winding armature can effectively reduce the armature deceleration characteristics and improve the system efficiency. The experiment was carried out by setting up a 4-stage coil launcher system. The simulation and experimental results show that it is in accordance with the actual demand to change the armature parameters to reduce the armature deceleration. Conclusion for the synchronous induction coil gun design reference.
