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 for identifying chaotic behavior due to bouncing-ball dynamics in a drivetrain torsional system is described. In this paper, the method is applied to the unstable vibration behavior caused by the dynamic backlash characteristics of a dual mass flywheel (DMF) to confirm the detected chaotic behavior can be classified as a bouncing-ball system and to show the effectiveness of the method. Both 1D simulation and real vehicle experimental data are used as validation data. |
