| 摘 要： | 将分数阶微积分引入Maxwell粘弹性流体的本构方程中,建立修正的Maxwell模型以描述磁流变液.通过贮能模量和耗能模量曲线,研究磁流变液的阻尼特性.在不同的磁流变液体组成参数实验条件下,理论的贮能模量和耗能模量能够与实验结果很好拟合,且模型阶数有着明显变化.研究表明,分数阶的本构方程能够很好地描述磁流变液的阻尼特性,方程分数阶算子与磁流变液物质参数有关.

| Abstract: | Fractional calculus is introduced to study the constitutive equation of Maxwell viscoelasticity fluids,and establish the modified Maxwell model to describe the magnetorheological fluids(MR fluids for short).The curves for storage modulus and loss modulus are used here for the analysis of the damping characteristics of magnetorheological fluids.Under the different experiment conditions about the constituent parameters for MR fluids,the theoretical storage modulus and loss modulus can fit the corresponding ex... |
