| Abstract(J) | オーバーターニングモーメントが発生する主要因は， 横力によって接地面が横移動することと， キャンバー角によるタイヤ中心と接地面との横偏差であるとされていたが， これらの要因で説明がつかない分について補正を加えたのが本モデルである.補正はマジックフォミュラーの横力関数を使った.本モデルを使用すると， 転覆の計算精度が向上する． Translation |
| Abstract(E) | The new tire model of the Overturning Moment (OTM) characteristics and the influence of OTM on the vehicle behavior have been presented. At first, the new OTM model was developed based on the so-called Magic Formula tire model. The concept of the new model is to identify the difference between the simple model and the measurements to the newly defined functions. It was seen that the new model agreed very well with the measured data in the wide range of tire vertical load, slip angle and camber angle. Then, the influence of tire OTM on the vehicle rollover was investigated in the full vehicle simulation by adding rather large steering angle input. The calculated results with the use of three different tire models (without OTM, simple model, new model) were compared with the experimental result. |
