摘要
本文提出了用静电耦合法测量高阻尼合金内耗温度谱仪器的设计。试验结果表明,该仪器能在50—3000Hz频率范围内测量高阻尼合金内耗的温度谱。该仪器具有结构合理、测量准确、操作方便、也可用于低内耗金属材料测量等优点。
This paper makes a design of the apparatus which is used to measure the temparature spectrum of internal friction for high-damping alloys by the method of electrostatic coupling. The experiment results show that the temparature spectrum can be measured ranging from 500 to 3000 Hz.The apparatus has the advantages of reasonable structure,convenient ope-ration and may be used to measure the metal of low internal friction.
