摘要
针对利用电火花打点计时器研究弹簧振子简谐运动中存在的问题,进行了逐一地分析和改进,改进后的实验仪通过霍尔继电器模块可以实时、直观、准确地描绘出4种典型振动图像,同时通过改变弹簧振子的质量获得不同振动周期的图像.
Aiming at the problems in the visualization of the simple harmonic motion of spring oscillator by using the spark-spot timer,analysis and improvement were carried out.The improved experimental method could draw four typical vibration curves in real time intuitively and accurately by using the Hall relay module.At the same time,the curves of different vibration periods were obtained by changing the mass of the spring oscillator.
