根据同步感应线圈发射器工作原理,建立了3级电磁线圈垂直发射器(electromagnetic coil vertical launcher,EMCVL)数学模型,利用Ansoft电磁仿真软件对其发射过程进行了仿真,得到了电磁场分布规律和动态特性曲线。结果表明:EMCVL低速发射大载荷过程中加速过程比较平稳,容易充分实现各级驱动线圈对发射组件的加速效果;发射过程中电磁场主要集中于驱动线圈和电枢外侧间隙,再逐渐向四周扩散,电枢所受的电磁力位置主要位于电枢尾部外侧,所以在实际设计中一定要考虑对电枢尾部结构的加固;EMCVL通过适当的改变电源储能参数、驱动线圈级数等途径,能够实现多类型载荷的发射。
According to the working principle of synchronous induction coil launcher, a mathematical model of 3-level electromagnetic coil vertical launcher (EMCVL) was established. The launching process was simulated by Ansoft electromagnetic simulation software, and the electromagnetic field distribution law and dynamic characteristics curve. The results show that the accelerating process of EMCVL is relatively smooth during low-speed launching of large loads, and it is easy to fully realize the accelerating effect of the driving coils on the transmitting components. During the launching process, the electromagnetic field mainly concentrates in the gap between the driving coil and the armature, Armature suffered electromagnetic force is mainly located outside the tail of the armature, so in the actual design must take into account the structure of the rear armature reinforcement; EMCVL through appropriate changes in power storage parameters, the number of drive coils and other ways to achieve Launch of multiple types of loads.
