基于PASCO系统的材料杨氏模量的测量

Study on the Method of Measuring Young’s Modulus Based on PASCO System

通过对传统实验仪器和测量方法进行改进,利用PASCO实验系统设计一套基于静态拉伸法测量材料的杨氏模量实验方案。利用力传感器和转动传感器测量材料的应力和应变数据,并使用Science Workshop数据采集软件对数据进行采集处理。得到待测材料的杨氏模量。该实验方案与传统静态拉伸测量方案相比,实验结果更加准确,适用范围更广。

Based on static tensile method,we design a set of Young’s modulus experiment scheme within the PASCO experimental system through the improvement of traditional experimental instrument and measuring method.By using the Science Workshop data acquisition software to collect and process the data,we get the Young’s modulus of the material.It is shown that the results of Young’s modulus are more accurate and the adapter range is more extensive compared with those obtained from the traditional static stretching measurement scheme.
