摘要

针对原有拉伸法杨氏模量测量装置的一些不足，对大学物理实验中的拉伸法杨氏模量测量装置进行了改进。新设计的实验装置将整个仪器水平放置，被测金属丝通过两个快速夹头固定，利用定滑轮组使被测钢丝在滑轮上迂回缠绕，增加被测金属丝的长度，金属丝的伸长量用数字千分表直接测量。改进后的杨氏模量测量装置结构简单，操作简便，测量快速准确，精度高，使用效果好。

Abstract:

In view of some shortcomings of the original device for measuring the Young's modulus of the tensilemethod ,the device for measuring the Young's modulus of the tensile method in college physics experiments hasbeen improved.The newly designed experimental device places the entire instrument horizontally , fixes themeasured metal wire through two quick change chucks, and uses a fixed sliding wheel group to make themeasured steel wire twist on the pulley to increase the length of the measured metal wire , The elongation of themetal wire is directly measured with a digital dial indicator. The improved Young's modulus measuring devicehas simple structure , simple operation ,fast measurement , high accuracy and good use effect.

Key words: Young's modulus experimental device improvement
