磁性流体の粘性ダンパの振動特性に関する基礎的研究

抄録

Basic studies of a magnetic fluid viscous damper are carried out theoretically and experimentally to clarify the effect of an applied magnetic field on the characteristics of a vibrating spring-mass system in the magnetic fluid. Experimental study shows that the application of magnetic field is effective reducing the resonance characteristics of the system. Theoretical analysis which is conducted by taking into account the aggregate of magnetic particles shows reasonable agreement with the experimental data.
