摘要
单摆振动实验的数字化传输和演示是实验教学中的一个值得讨论的基本问题.当前单摆振动实验的研究以定性建立理论模型为主,只能得到单摆振动的示意图像,且实验效果不好.本文针对当前的单摆振动实验进行改进,并通过定量计算,给出较精确的实验设计要求,得到了很好的实验效果,为该实验提供完善的理论依据和技术指导.除此之外,本文提出的实验方案不仅适用于单摆的简谐振动还适用于各种阻尼振动.
The digital transmission and demonstration of pendulum vibration is a basic problem of worthwhile discussion in the experiment teaching. Up to now, the researches of this prob- lem are mainly done with the qualitative model building, by which only the schematic diagram can be obtained with poor experimental effect. In this paper, we revised this vibration experi- ment by quantitative calculations which developed the accuracy of the experiment design and got better experimental effect which provided perfect theoretical basis and technical guidance for the experiments. Furthermore, our experiment design is not only suitable for the simple harmonic vibration of simple pendulum, but also suitable for all kinds of damping vibrations.
