ER流体を用いた振動減衰装置の履歴減衰特性に関する研究

抄録

Oscillation damping system using ER fluid (Electro-Rheological Fluid) from which viscosity changes by applying voltage is analyzed by experiment and the hysteretic damping characteristics is analyzed as nonlinear dynamic problem in this paper. Modeling of the synthetic combination of damping material and damping mechanism was dealt with especially, and the approximation formula which express change of the damping characteristics by change of voltage, frequency, etc., was verified by the comparison with an experimental result.
