基于差动电压传感器的杨氏模量实验改进

摘要

The traditional hall sensor using the beam bending method is used to measure the young’ s modulus of the experiment is improved.Aiming at the shortcomings of the original experiment device,switch to measure-ment of tiny displacement differential voltage sensor,microcontroller for data processing,solve the complex ex-periment device,complex data processing and so on,to improve the precision of the experiment,realized the physical experiment device of digital and intelligent.%对传统使用霍尔传感器横梁弯曲法测量的杨氏模量实验进行了改进。针对原实验装置的不足，改用差动电压传感器测微小位移，利用单片机进行数据处理，解决了实验装置繁琐、数据处理复杂等问题，提高了实验的精确度，实现了物理实验装置的一体化和智能化。
