| 摘 要： | 重接式电磁发射实际上是一种特殊形式的线圈式电磁发射,由在发射体内感生的涡流和线圈磁场相互作用产生电磁力来加速发射体.发射体内的涡流对发射器的性能至关重要.本文在涡流的二维模型的基础上,分别对涡流和其产生的磁场特性进行了仿真分析,所获得的结果对进一步提高发射器的性能有参考作用.

| Abstract: | The reconnection electromagnetic Iaunch(EML)is a special type of coil EML.The interaction between the magnetic field of the coil and the eddy current induced in a projectile can Iaunch the projectile.The eddy current is extremely important for the performance of Iauncher.Based on 2-D model of the eddy current,the characters of eddy current and magnetic field generated by the eddy current are analysed in this paper.Lastly,the simulation is performed and the results are useful for improvement of the launcher's performance further. |
