摘要
电磁发射装置中的行波磁场是推动射弹最重要的因素.为研究行波磁场对铝质射弹的作用规律,基于圆筒型直线感应电机的相关理论,研制了电磁发射装置样机.通过实验,系统地研究了行波磁场对电磁发射装置推进性能的影响.实验结果表明:随着外加三相电源频率或电压的升高,电磁推力增大、射弹的运动速度提高,与理论分析结果一致.
The traveling wave magnetic field is the most important factor for the elec- tromagnetic launcher in propelling the projectile. In order to study the action of the traveling wave magnetic field on aluminum projectile, an electromagnetic launcher pro- totype was developed based on the theory of cylindrical linear induction motors. The ex- periments give a systematic research on the influence of traveling wave magnetic field on the propulsion performance of the electromagnetic launcher. The experiment results re- veal that the electromagnetic force and the projectile movement speed increases as the three phase power frequency or voltage increases. This conclusion proves to be in accord with the theoretical analysis.
