摘要

本文设计了一种用于测量液体黏度的阻尼振动装置.该装置以一个做欠阻尼振动的弹簧振子为核心,利用光电接近开关收集数据,并在数字示波器上显示图像,再将该图像数据传递到计算机上进行分析.该方法的适用范围广,便于收集与分析实验数据,避免了实验中的多种干扰因素,消除了传统落球法实验的弊端,提高了实验测量的准确度.

Abstract

In this paper,a damping vibration device for measuring the viscosity coefficient of liquid is designed.A spring vibrator is taken as the core,and a photoelectric proximity switch is used to collect data.A digital oscilloscope is employed to display the image and transmit the image data to computer for analysis.This method has a wide range of application,is convenient for collecting and analyzing experimental data.It also avoids various interference factors in the experiment and eliminated the disadvantages of traditional fallingsphere method.It also improves the accuracy of experimental measurement.
