中文摘要 |
本研究採用電腦輔助工程(CAE)模擬來研究輪胎和路面之間的附著力。建立輪胎與路面的有限元素模型,探討輪胎-路面附著力與滑移率的關係。考慮了輪胎轉速、表面滑動摩擦係數、負荷、壓力、橡膠材料等參數。在乾燥道路條件下進行模擬以確定附著係數,然後分析載重、壓力和橡膠材料對此係數的影響。研究結果表明,除了地面摩擦係數之外,輪胎負載和輪胎壓力的變化也會顯著影響輪胎與地面之間的接觸面積和摩擦力。輪胎接觸面積越大,附著係數越高,進而產生更大的最大摩擦力。透過CAE模擬,研究闡明了不同輪胎與地面接觸情況下各種因素的關係和影響,有助於更好地理解和優化輪胎性能和安全性。 |
英文摘要 |
This study employs computer-aided engineering (CAE) simulation to investigate the adhesion between tires and road surfaces. A finite element model of the tire and road was established to explore the relationship between tire-road adhesion and slip rate. Parameters such as tire rotational speed, surface sliding friction coefficient, load, pressure, and rubber material were considered. The simulations were conducted under dry road conditions to determine the adhesion coefficient, followed by an analysis of the effects of load, pressure, and rubber material on this coefficient. The findings indicate that, in addition to the ground friction coefficient, variations in tire load and tire pressure significantly impact the contact area and frictional force between the tire and the ground. A larger tire contact area correlates with a higher adhesion coefficient, resulting in greater maximum frictional force. Through CAE simulations, this research elucidates the relationships and effects of various factors in different tire-ground contact scenarios, contributing to a better understanding and optimization of tire performance and safety. |
