| 摘 要： | 本文以动态杨氏模量实验~(1])为基础,探讨铜棒在室温环境下动态杨氏模量的大小,采用增加悬挂点数目、用游标卡尺测量悬挂点位置、用Origin 7.5统计软件~(2])统计,拟合出铜棒发生共振时,共振频率与悬挂点相对位置的散点图、拟合方程、拟合曲线,并求出了相对误差很小的铜棒的动态杨氏模量大小,反映出此方法的优势.

| Abstract: | Basing on the experiment about dynamic metal Young's modulus of copper rod,it discusses the numerical value of dynamic Young's modulus of copper rod in the condition of room temperature.It increases the number of suspension points、measures the locations of suspension points by vernier calipers、stats the data by Origin 7.5.It fits the scatter diagram、fitted equation、fitted curve between resonant frequency and relative suspension points when it comes into being resonance .It brings off very low relation error of dynamic Young's modulus of copper rod ,which response the superiority of the method. |
