Intelligentization of Experiment System Measuring Moment of Inertia Based on Torsion Pendulum Method
Author(s): 
Pages: 23-26
Year: Issue:  2
Journal: EXPERIMENT SCIENCE AND TECHNOLOGY

Keyword:  转动惯量微机应用扭摆法;
Abstract: 介绍了一种用PC机完成测量周期、计算转动惯量数值的新方法.从硬件和软件方面详细说明了如何用一台微机实现对整个实验系统中所有时间量的测量和对实验数据的处理.对改进后实验系统所测得的结果与传统方法的测量结果进行了比较,可以看出:此方法接口电路简单,时间测量准确,计算速度快,实验结果误差小,而且易于推广.
