摘要
这里分析了一种磁流变减振器的原理,用粘度模型描述了磁流变液随外加磁场变化的流变特性,得到的阻尼力方程为这种减振器的设计提供了理论基础。研究结果表明:随着外加磁场的增加,磁流变液的表观粘度增加,减振器产生的阻尼力增大。
In this paper the principle of a magnetorheological （MR） damper is analyzed. The viscosity model is used to describe viscous characteristics of the MR fluids subject to an applied magnetic field. The equation for the damping force is derived to provide the theoretical foundation in the design of the damper. The results show that with the increase of the applied magnetic field the apparent viscosity of MR fluid and the force is increased.
