摘要
从物理学基本原理出发,以线圈炮的简单模型为例,导出了计算弹丸所受磁场力的两种表示.证明了它们的等价性,并把结论推广到一般线圈炮的情形.
There are expressions of two kinds about how to calculate the magnetic force accelerating the projectile in coilguns. However, the inductance gradient expression had been quoted incorrectly by many researchers. It is necessary to demonstrate them correctly and prove their equivalent relation. In this paper, these problems are solved perfectly on the base of several physics principles.
