【摘要】 通过实验研究了磁流体的阻尼力特性,提出了基于粘性阻尼和回滞阻尼组成的迟滞阻尼力模型,并应用迭代摄动法分析了含有磁流体阻尼器梁结构的特征值谱．结果表明：磁流体阻尼力可以显著地减小系统的振动,迭代摄动法是研究含有磁流体阻尼力非线性方程的有效方法．更多还原

【Abstract】 Damping force properties of Magnetorheological fluid are experimented and the viscous and bilinear hysteresis damping model is established and presented in this article.The egenvalue spectum of simply supported beam with magnetorheological fluid damper is analyzed by iterative perturbation method.Study results show that vibration amplitude decreases effectively as damping force of the magnetorheological fluid increases.Conclusion also includes that iterative perturbation method is valid method to nonlinear equations with damping force of magnetorheological fluid.更多还原
