摘要: 在小内耗并且内耗参数只与切变振幅相关的前提下,采用分析力学方法求出由单自由度自由衰减振动扭摆位移采样值,获取材料非线性内耗和切变模量参数的计算方法。

Abstract: Assuming the smallness of the internal friction which depends only on the amplitude of shear strain, based on analytical mechanics, we developed a calculation method to obtain non-linear material parameters of internal fiction and shear modulus from the sampled data of tor-sional displacements of the free-decay oscillation for the torsional pendulum.
