舰载导弹线圈发射器模型工作过程仿真

Working Process Simulation of Electromagnetic Coil Launcher Model for Shipborne Missile

为了克服传统舰载导弹垂直发射器的弊端,提出了一种新型舰载导弹发射器模型,阐述了该模型的基本组成和工作原理,建立了发射器工作过程的数学模型,以三级发射器为例对其工作过程进行了动态仿真,得到了发射器工作过程中放电回路中的电流、发射组件所受电磁力、速度及位移等参数随时间的变化规律。对比分析了通过改变系统储能和发射线圈级数对系统工作特性的影响。结果表明:弹射线圈较驱动线圈具有更好的加速能力;发射组件的速度对其所受的电磁力有较大影响,随着速度的增加,发射组件所受电磁力减小;适当改变系统储能和发射线圈的级数可以实现导弹的垂直发射。

In order to overcome the demerits of traditional vertical launcher of shipborne missile, a new type model of electromagnetic coil launcher for shipborne missile （EMCLSM） is introduced. The fundamental constitution and operation principle are stated. Mathematical model of the working process is established. In three-stage launcher, for example, the working process of EMCLSM is studied by simulation. The current waves of discharge loops vs. time and the electromagnetic force, the velocity and the displacement vs. time in the working process of EMCLSM are given. Two kinds of different schemes which include changing energies in energy storage system and changing the number of stages of the launching coils are analyzed comparatively. The simulation results indicate that catapult coil has better acceleration capacity compared with drive coil. The electromagnetic force acting on the launching package is affected by its velocity. The force decreases as the velocity increases. It is capable of launching missiles from vertical position by changing energies in energy storage system and the number of stages of the launching coils suitably.
