触发位置对异步线圈电磁推进效率影响分析

Effect of Armature Position on Efficiency of Asynchronous Coil-Propeller

构建了异步感应线圈推进器的数学模型,利用集总电路的方法得出了电枢受力方程以及运动方程,利用ANSYS模拟推进过程,得出了电枢初始位置影响推进效率的规律。在推进器实验平台进行了大量实验,获得了电枢在不同初始位置时的出口速度及对线圈推进器效率的影响规律,验证了理论分析的正确性,存在一个推进效率最高的最佳触发位置。

The mathematical model of the asynchronous induction coil-propeller was established, and the formula of the armature force and the equation of motion were obtained by using the lumped circuit method. Then, the software ANSYS was used to simulate the propulsion process, and the rule of the initial position of the armature was summarized. A large number of experiments were carried out using the propeller’s experimental platform, and every speed of the armature, as well as the effect on the efficiency of asynchronous induction coil-propeller, at different initial positions was obtained. It verifies the correctness of the theoretical analysis, that is, there is a best trigger position to make the propulsion efficiency the highest.
