| 中文摘要: |
| 采用轮胎专用有限元分析软件TYSYS对3种方案11.00R20 18PR全钢载重子午线轮胎(方案1～3轮胎的1#带束层宽度分别为165，137和175 mm)进行有限元分析，以确定1#带束层的最佳宽度。有限元分析结果表明：3种方案轮胎充气外缘尺寸均符合国家标准要求；在相同负荷下，随着1#带束层宽度增大，轮胎下沉量逐渐减小；在大负荷下，方案2轮胎胎肩局部应变能的极大值以及应变能之和均较小，有利于提高轮胎的使用性能。耐久性试验结果表明：方案2轮胎的耐久性能优于方案1轮胎，与有限元分析结果一致。 |
| 英文摘要: |
| In order to optimize the width of 1# belt，three 11.00R20 TBR tires (from tire 1 to 3，the widths of 1# belt were 165，137 and 175 mm，respectively) were analyzed by the FEA special software.The FEA results showed that，the inflated peripheral dimension of three tires reached the requirement of national standard；under same load，the tire deflection decreased as the width of 1# belt increased；under large load，both the max strain energy and total strain energy in tire shoulder of tire 2 were smaller，which could be beneficial to tire performance.The endurance test results showed that，the endurance of tire 2 was better than tire 1，which was in accordance with the FEA results. |
