阻尼材料动态性能指标主要指材料的实剪切模量G′和损耗因子β。它们是温度和频率的两维函数而不是一维函数,但是可以利用温频当量关系用一维函数来表示。本文分析了这些因素和材料性能之间的函数关系,同时指出DM—1型动态模量仪用共振法测量温谱图时存在的问题以及修正方法,试验结果与理论分析是一致的。 Damping material dynamic performance index mainly refers to the material of the real shear modulus G ’and loss factor β. They are two-dimensional rather than one-dimensional functions of temperature and frequency, but can be expressed as one-dimensional functions using the temperature-frequency equivalence relationship. This paper analyzes the functional relationship between these factors and material properties, and points out the problems existing in the measurement of the thermogram by the resonance method of the DM-1 dynamic modifier and the correction method. The experimental results are consistent with the theoretical analysis.
