本研究主要是針對輪胎性能影響車輛轉向的轉向行為。為了獲得相關的數據,其中擷取的參數包括車輪與車身側滑角、方向盤轉向角度與扭力、偏轉率、向心加速度,並且介紹兩組雙軸式光學速度計、陀螺儀、方向盤角度扭力計,這些儀器分別安裝在實驗車上。
輪胎的轉向剛性會受到扁平比與輪胎壓力所影響,因此,這兩項參數被視為影響車輛轉向特性最重要的條件,本研究改變這兩項參數,並且在不同的車速下分析車輛轉向行為。
在進行道路測試時,假設車輛在過彎的情況下,形成一個等速穩定圓行駛。經過多次的道路測試後,分析車輛動態參數,其中分析的參數分別為車輪與車身側滑角、偏轉率、向心加速度。利用上述參數分析,扁平比與輪胎壓力在不同車速下的影響,並且可看出,扁平比、輪胎壓力與車速對試驗車在穩定圓測試中有很大的影響。

關鍵字:扁平比、輪胎壓力、轉向剛性、向心加速度、偏轉率
This study is mainly aimed at the influence of the tire property on the cornering behavior when the vehicle takes a turn. In order to obtain the related data including steering angle, yaw rate, lateral acceleration, wheel and body sideslip angle, the equipments including steering wheel angle/torque gauge, gyroscope, non-contact optical two-axle speed sensors are introduced and respectively mounted on the test-car.
The cornering stiffness of the tire varies with different tire pressure and aspect ratio, and hence,the two parameters are considered to evaluate the influence on the vehicle cornering behavior under various vehicle speed conditions in this study.
In the road testing, the test-car is assumed to run a steady circle at a preset constant vehicle speed in case of a fixed turning radius. After a series of road testing, the main data including wheel sideslip angle, body sideslip angle, and yaw rate are really recorded, and then taken an analysis to investigate the relation between these data and the parameters including tire pressure, aspect ratio and vehicle speed. In consequence, it can be seen that the tire pressure, aspect ratio and vehicle speed have considerable influence on the cornering behavior when the test-car runs a circular path.

Keywords: aspect ratio, tire pressure, cornering stiffness, lateral acceleration, yaw rate.
