| 摘 要： | 本文研究了粘弹性阻尼材料的耗能机理和动态阻尼特性,采用分数导数模型,并与温频等效原理相结合,得到了粘弹性阻尼材料的复模量、损耗因子与温度关系的参数化数学模型;并结合粘弹性阻尼材料的DMA测试实验数据对模型参量进行了拟合。实验结果和误差分析表明拟合的数学模型能够准确反映粘弹性材料在定频率变温度条件下的动力学特性的变化情况。

| Abstract: | Energy dissipation mechanism and dynamic damping performance of viscoelastic damping material were studied in this paper.By using fractional derivative model and temperature-frequency superposition principle, the parameterized mathematical expressions were obtained.In the expressions,the individual relation between the complex modulus,loss coefficient and temperature was described,and the parameters were obtained by fiting the experimental data of viscoelastic damping material dynamic performance tested by ... |
