汽車在行駛過程中由於本身重量及路面摩擦生熱，使得輪胎產生顯著的熱量積累，對輪胎的性能及壽命造成嚴重影響，尤其鋼絲環帶作為輪胎的關鍵結構部件之一，其設計對熱量積累及剪應力分佈更具有重要的影響。本研究旨在利用有限元素軟體對轎車用輪胎肩部結構進行發熱率的分析與探討，進而找出最佳設計以降低輪胎之熱量積累，提升輪胎的整體性能及壽命。首先，利用 AutoCAD 建立輪胎的二維幾何模型；然後於ABAQUS中設置網格；最終將模型匯入商用有限元素求解器中進行發熱率之模擬分析，通過各國法規規定設置邊界條件，模擬輪胎在實際運行中的熱量積累情形；最後，經由
輪胎樣品實體測試與模擬結果進行比對研究，結果顯示：1)鋼絲環帶端點處是熱量積累的高溫區域；2)優化後的肩部結構設計與原始相比，發熱率從5.746改善至2.864，約下降50%；3)結構優化後之走行時數達到336小時，比原始結構144小時提升了約1.3倍，證實了優化肩部結構設計的有效性，這對提高輪胎的耐久性及安全性具有重要意義。

During the driving process, significant heat accumulation occurs in tires due to the vehicle's weight and road surface friction, which severely affects the performance and lifespan of the tires. This is especially true for the steel belt, a key structural component of the tire, whose design significantly influences heat accumulation and shear stress distribution. This study aims to analyze and investigate the heat generation rate in the shoulder structure of
passenger car tires using finite element software to identify the optimal design that reduces heat accumulation and enhances overall tire performance and lifespan. First, a two-dimensional geometric model of the tire is created using AutoCAD. Then, the mesh is set up in ABAQUS. Finally, the model is imported into a commercial finite element solver for heat generation rate simulation analysis. Boundary conditions are set according to international regulations to simulate the heat accumulation in tires during actual operation. The results of physical testing of tire samples are compared with the simulation results. The findings
indicate that： 1) the endpoints of the steel belt are high-temperature areas of heat accumulation; 2) the optimized shoulder structure design reduces the heat generation rate from 5.746 to 2.864, a decrease of approximately 50% compared to the original design; 3) the running hours of the optimized structure reach 336 hours, which is about 1.3 times the 144 hours of the original structure, confirming the effectiveness of the optimized shoulder structure design. This has significant implications for improving the durability and safety of tires.
