| 摘 要： | 磁阻驱动器是一种新型直线电动机。其工作原理是通过驱动线圈中的电流与抛体中的磁化电流之间的电磁力而加速抛体至预定速度。在给定驱动线圈结构和抛体参数情况下,抛体与驱动线圈组成的等效电感是驱动线圈中电流和抛体位置的非线性函数。通过有限元软件,仿真得到了等效电感数据,联立机电系统电压和功率平衡方程数值求解了磁阻驱动器发射过程中电容器上的电压及抛体出口速度的变化情况。利用铁磁质抛体进行了试验,验证了磁阻驱动器的实验出口速度与数值计算结果较为一致。

| Abstract: | Reluctance driver is a new type of linear electromotor.According to the electromagnetic force between the current in driving coil and the magnetic current in projectile,the projectile would be accelerated to a scheduled velocity.In this paper,the theory model and its calculation methods has been introduced.Once the structure of the driving coil and projectile parameters have been given,the equivalent inductance between driving coil and projectile has became the non-linear function of the current in the driv... |
