摘要: 提出了悬丝耦合音频共振的实验方法,用来测定材料的杨氏模量、剪切模量和泊松比,并分析了测量误差来源,进而运用此方法测定了25号碳钢(退火)的杨氏模量和剪切模量.

关键词: 共振, 杨氏模量, 剪切模量, 受迫振动

Abstract: In order to determine Young modulus, shear modulus and Poisson ration of material, the experimental method on hanging string audion frequency coupling resonance is presented. The source of the experimental error is analysed,and Young modulus and shear elastic of 25^# steel are determined.

Key words: resonance, Young modulus, shear elastic modulus, forced vibration
