螺旋线圈型电磁发射器有限元动态数值仿真

Dynamic Numerical Emulation of A New Electromagnetic Launcher

基于有限元方法,对螺旋线圈型电磁发射器的动态发射过程进行了数值分析。螺旋线圈型电磁发射器弹丸可采用线圈弹丸和铁磁弹丸,对比分析了两种弹丸运动过程中受力和速度随时间的变化关系。

A new electromagnetic launcher was designed based on the basic structure of helical coil electromagnetic launchers （HCEL）. The moving processes of helical coil electromagnetic launchers （HCEL） with coil armatures and ferromagnetic armatures were analyzed numerically. Analyzed the force and velocity versus time of the two armatures contrastively.
