고주파영역에서의 MR유체 특성연구

초록

In this study, the MR property characterization at high frequency region is performed. An experimental setup based on wave transmission technique is made and the storage modulus as well as loss modulus of MR fluid are found from the measured data of speed sound and attenuation. Details of the experiment are addressed and the obtained storage and loss moduli are addressed at 50-100 kHz.
