摘要/Abstract

摘要： 为了对多段直线感应线圈推进器的工作过程进行研究，利用数值仿真的方法对两段直线感应电磁推进器进行了分析。并与实验结果进行了对比，证实了仿真结果的准确性。首先通过集总参数电路模型建立了直线感应线圈推进器的数学模型，根据数学模型利用MATLAB编写了系统动态过程的仿真程序。其次，对设计的两段直线感应线圈推进器进行了数值仿真，给出了抛体受力及速度变化曲线，同时给出了抛体分片平均温升变化。最后，搭建了两段推进器的实验平台，并对仿真结果和实验结果进行了比较分析。在第一段单相电容容量为1 500 μF，电压3 kV，第二段单相电容容量为720 μF，电压5 kV的情况下，将质量为300 g的抛体加速到204 m/s的出口速度。这为下一步的多段直线感应电磁推进器的设计提供了理论指导和实验基础。

Abstract: To study the transient process of multi-section linear induction propeller, a two-sections propeller was simulated and analyzed numerically. Also, its was tested to verify the simulation results. Based on the lumped parameter circuit method, a simulation model of the capacitor driven linear induction propeller was built. Then, the simulation code for the dynamic process in the system was programmed in MATLAB. The projectile velocity and force were predicted by using simulation, and the distribution of average temperature rise in the sleeve was described. Finally, the test bench of the propeller was described. Experimental results coincide with theoretical prediction better. It can accelerate a projectile of 300 g in weight to a muzzle velocity of 204 m/s, if the voltage and capacitance on the capacitors of the propeller are 3 kV, 1 500 μF in the first section, and 5 kV, 720 μF in the second section, respectively.
