摘　　要：利用霍尔效应制作测量模拟轮毂转速实验装置,根据霍尔元件和光电门的工作原理,通过脉冲计数的方法来模拟实现轮毂转速测量。通过实验结果与理论值进行比较,发现二者在实验误差允许的范围内非常吻合。Based on hall effect measure speed of the simulated wheel.According to the working principle of the hall element and photoelectric door,that measured speed of the simulated wheel by pulse counting method.By comparing experimental results with the theoretical value,it found very anastomosis in the range of experimental error allowed.
