Development of the Damping Device Using MR Fluid and Application of HV
MR 流体を用いた制振装置の開発とHV への適用
The authors developed a damping device that used a magneto-rheological (MR) fluid, whose yield stress varies with applied magnetic field intensity. The device consists of two rotating disks with the MR fluid between them. It reduces vibrations by varying the viscosity of the fluid, and thus the moment of inertia of the rotating bodies, by controlling the magnetic field using the current in a stator coil. When this device was applied to the flywheel of a hybrid vehicle, it reduced the energy needed to start the engine, and improved the engine response.磁場の強度を変更することでせん断力が変化する磁気粘性流体(MR流体)を，2つの回転体の間に封入し，慣性モーメントと粘性特性を磁場の強度で制御する制振装置を開発した．これをHVのフライホイールに展開することで，エンジン始動エネルギの低減とエンジンの応答性向上が見込まれる．この原理と効果について報告する．
