直线感应电磁发射器分析与优化

本文对一个两段直线感应电磁发射器进行了分析与优化设计。首先建立了电容驱动的直线感应电磁发射器的数学模型。通过MATLAB编写了系统暂态仿真的仿真程序,给出了系统仿真的流程图。其次比较了直线感应电磁发射器三相电源不同的触发相序对发射性能的影响,得到了最优的触发相序。分析了不同抛体初始位置对出口速度和动能转换效率的影响。最后比较了两段直线感应电磁发射器在第一段电源电压改变时对系统的影响,以及第二段电源电压改变时对系统的影响。从而为下一步的实验提供了理论依据。

Optimization and analysis of linear induction launcher

In this paper, a two sections linear induction launcher was analyzed and optimized by using computer simulation. Firstly, according to the principles of the mesh-matrix method, a lumped parameter transient model for the analysis of the dynamic conditions was built. The simulation code was programmed by MATLAB. The flow chart for the computer simulation was drawn. Secondly, the effect of varying delay between phases for the 3-phase firing sequence in section 1 was studied and the best time intervals between the firing of the three phases were obtained. It also studied the initial position of sleeve in the first section which affected the muzzle velocity and the kinetic energy transfer efficiency. Finally, the effect of voltage changes in the first section was studied. The muzzle velocity and energy transfer ration was analyzed when the voltage in the second section increased. The computer simulation results have provided a theoretical guidance and experimental basis.
