载流电枢电磁线圈发射器运行特性分析

电枢是电磁线圈发射器能量转换的关键部分,以此为研究对象,提出串联载流电枢发射器和并联载流电枢发射器的结构模型,通过分析2种载流电枢发射器的工作原理和结构特点,得到了系统微分方程,并利用MATLAB建立了载流电枢发射器的系统仿真模型,分析了发射器的运行特性。分析结果表明,载流电枢发射器发射过程无拖拽效应,串联载流电枢发射器适于载荷在20 m/s以下的加速段使用,适于选用低压的电容器电源; 并联载流电枢发射器可用于载荷在50 m/s以上的加速段使用,适于选用高电压电容器。研究结果对电磁线圈发射器电枢结构设计具有一定的指导意义。

Running Characteristics Analysis of Electromagnetic Coil Launcher With Current-carrying Armature

The armature is the key part for energy exchange in electromagnetic coil launcher (EMCL).The structural model with series-current armature launcher ( SCCAL ) and parallel-current armature launcher ( PCCAL) was proposed .System differential equation was deduced by analyzing the working principle and the structure character of two kinds of current-carrying armature launcher ( CCAL) .Systematical model of the CCAL was built with MATLAB , and the launching character was analyzed .The analysis shows that there is no pulling effect in launching process in CCAL .SCCAL is more suitable for accelerating payload with low-velocity less than 20 m/s by using low-voltage-capacitor power-supply .PCCAL can be used to accelerating payload with high velocity more over 50 m/s by using high-voltage-capacitor power-supply . The conclusion has great significance for guiding the structural design in EMCL .
