金属板接近交流载流线圈时会产生排斥力,但是产生排斥力的原因以及如何计算力的大小尚有待研究。本文提出一种理论推导与工程实践经验相结合的方案,既可以解释电磁驱动系统在空间中产生力的原因,也可以计算出低频和高频波载流线圈与附近金属板的推力。推导和求解公式时使用了多次循环迭代以及累加变换消元的运算步骤,之后通过实验成功地确定了未知参数,结合Matlab程序求出了不同情况下积分的解。最后,经实践验证,该方法较好地解决了交流电磁驱动线圈的复杂推力计算问题。 |

A repulsive force is generated when the metal plate is close to the AC current-carrying coil, but the main reason why the repulsive force is generated and how to calculate the magnitude of the force is not very clear. This paper presents a scheme that combinestheoretical derivation with practical engineering experience, which can explain why electromagnetic drive systems generate forces inspace and calculate the thrust for both low and high frequency wave current carrying coils with adjacent metal plate. The derivation andsolution of the formula use multiple iterative cycles and accumulation transformation elimination steps. Subsequently, the unknown parameters are successfully determined through experiments, and the solutions of the integrals under different conditions are obtained bycombining Matlab programs. Finally, the feasibility of this method is verified in practice, and the complicated thrust calculation problem of AC electromagnetic drive coil is solved well. |
