金属管杨氏模量与温度关系的实验研究

Experimental Study on the Relationship between Young's Modulus and Temperature of Metal Tube

采用动力学共振法测量不同管径金属管的共振频率,运用origin软件对实验数据进行二次函数拟合,代入管状材料杨氏模量的计算公式得到试样的杨氏模量。通过加热控温设备改变金属管温度,研究金属管杨氏模量与温度的关系。实验结果表明金属管杨氏模量的大小与温度成线性关系。

Adopt the Dynamic resonance method to measure the resonance frequency of different diameter tubes.The experimental data have been fitted by a quadratic function through the Origin software and put the data into the tubular material Youngˊs modulus calculation formula to obtain the values of Youngˊs modulus. Change the temperature of metal pipe by heating temperature control device to study the relationship between Youngˊs modulus and temperature closely.Use Origin software to fit the experimental data,which shows that the youngˊs modulus of the metal tube is linear with temperature.
