三级电磁线圈垂直发射器工作过程仿真

Simulation of Working Process of Three-stage Electromagnetic Coil Vertical Launcher

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, mathematical model of threestage electromagnetic coil vertical launcher （EMCVL） is established. With the application of Ansoft, the dynamic simulation of its process is made. The electromagnetic field and the dynamic characteristic curves are given. The simulation results indicate that the launching package of heavy load is speeded smoothly in low speed, and the drive coil can make the best of its capability of driving the package. The electromagnetic field is focused between the drive coil and the armature＇ outside surface, and then spreads all around. The electromagnetic force is focused on the outside of the tail of armature, the fortification of the tail of armature should be considered. It is capable of EMCVL of launching multi-types of loads by changing energies in energy storage systems or the number of stages of the launching coils suitably.
