| Abstract(J) | 車両運動は平面運動を基本とするが，RollやPitchも操縦安定性と主観評価に影響する．本報告では，RollとPitchを考慮した4自由度モデルの複素固有値解析により振動モードを抽出し，車両挙動がモード重畳であることを踏まえ，ばね上挙動の発現メカニズムを解明 Translation |
| Abstract(E) | Vehicle dynamics are primarily governed by planar motion; however, roll and pitch significantly influence handling and subjective evaluation. Prior studies suggest that phase differences between roll and pitch during turn-in affect driver perception. While modal analysis has been applied to motorcycles, its use for four-wheel vehicles remains limited. This study formulates a four-degree-of-freedom model incorporating roll and pitch and solves the complex eigenvalue problem analytically to extract vibration modes. Furthermore, by demonstrating that vehicle behavior results from the superposition of these modes, the underlying mechanism of sprung-mass motion is elucidated. |
