| Abstract(J) | デュアルマスフライホイール(DMF)が内包する動的バックラッシ特性に起因する不安定な振動現象は，一般的な周波数分析手法であるSTFTを用いても振動挙動の特定が困難であった．そこで本報では，1Dシミュレーションおよび実車実験それぞれにリターンマップ手法を適用し，カオス的挙動の発生について研究した． Translation |
| Abstract(E) | A return map method to identify the chaotic behavior is described. In this paper, the method is applied to the unstable vibration behavior caused by the dynamic backlash characteristics of the dual mass flywheel (DMF), which has been difficult to identify the vibration behavior using the general frequency analysis method STFT, and it is examined whether the chaotic behavior and fractional harmonic vibration can be identified. Both 1D simulation and real vehicle experimental data are used as validation data. |
