摘要

摘要: 对硅橡胶粘弹性阻尼材料进行不同温度的频率扫描和动态位移扫描实验.采用经典Burgers模型和RT模型对该材料频率响应曲线的预言能力进行评估;基于RT模型, 本文提出改进的M-RT模型同时考虑了温度、频率和动态位移对材料动态力学行为的影响, 通过与实验结果的比较分析, 表明该模型能很好地描述该材料在宽温、宽频和宽动态位移的动态本构行为.

Abstract: The tests of frequency sweeping and dynamic displacement sweeping at different temperatures for the viscoelastic material silicon rubber were conducted.The predication capability of the frequency response behavior for Burgers model and RT model was evaluated.Based on RT model,M-RT model was proposed and considered the influence of temperature,frequency and dynamic displacement was considered.The comparison between the experimental and predicted results shows that the proposed model in the paper can predict the dynamic constitutive behavior very well under broad temperature,frequency and dynamic displacement.
