摘 要: | 引入了电桥法测量杨氏模量,用自制平行板电容器对传统的实验装置进行改进,用电容的变化来表征微小位移的变化,使用数字电桥测量仪作为信号采集下位机、PC机作为上位机并使用MATLAB作为信号处理软件,减小了人工测量等因素所产生的误差,由此给出了一种测量杨氏模量更精确的方法。

Young's Modulus Measuring Based on Ambergris AT810 Digital Bridge |

Abstract: | It introduces bridge measurement of Young's modulus,the traditional improved experimental setup with a homemade parallel plate capacitor,with the change in capacitance to characterize small changes in dis-placement,the use of digital bridge meter as the next signal acquisition position machine,PC machine as a PC and use MATLAB as a signal processing software to reduce the errors arising from manual measurements and other factors,and thus gives a more precise measurement of Young's modulus method. |
