轨道炮纵向后坐力被忽视的机理与黎曼力定律的复兴
An Ignored Mechanism for the Longitudinal Recoil Force in Railguns and Revitalization of the Riemann Force Law
摘要:
利用时变电流产生的电感应力来解释作用在轨道炮加速器轨道上的纵向后坐力。如在实验中所观察到的,该感应力是纵向于轨道的,并且在轨道的头部处可以是最强的。此外,对于闭合回路所产生的力,证明了以势能依赖于相对速度为基础的、与牛顿作用和反作用定律一致的黎曼力定律,可以归结为洛伦兹力定律。
英文摘要:
The electric induction force due to a time-varying current is used to account for the longitudinal recoil force exerted on the rails of railgun accelerators. As observed in the experiments, this induction force is longitudinal to the rails and can be the strongest at the heads of the rails. Besides, for the force due to a closed circuit, it is shown that the Riemann force law, which is based on a potential energy depending on a relative speed and is in accord with Newton's law of action and reaction, can reduce to the Lorentz force law.
