为了设计半主动粘滞阻尼器，对采用磁响应液的粘滞阻尼器的振动方程中的参数进行了基本的实验研究。我们使用了磁性活塞，它是由交替的磁性和非磁性材料制成的圆盘，用于流体的颗粒不沉淀。为了阐明减振效果，我们测量了频率响应和惯性力与位移之间的关系。阻尼器动态特性的结果可以用流体中聚集成链状的颗粒团来解释。并阐明了MCF作为阻尼器的适用条件。阻尼器活塞周围的表观密度对阻尼器的减振效果影响很大。
A basic experimental study was carried out to investigate the parameters in a vibration equation of a viscous damper utilizing a magnetic responsive fluid in order to design a semi-active viscous damper. We used the magnetic piston which has made with alternating layers of magnet and nonmagnetic material disks for particles of the fluids not to sediment. To clarify the damping effect, we measured a frequency response and a relationship between inertia force and displacement. The results of the dynamic characteristic of the damper can be explained by the cluster of particles aggregated like a chain in the fluid. We also clarify that MCF is suitable for the damper. The damping effect is strongly influenced by an apparent density around the piston of the damper.
