| 中文摘要: |
| 针对295/75R22.5载重子午线轮胎带束层角度进行优化设计，采用有限元方法进行二维充气仿真分析，并试制轮胎进行成品性能对比试验。有限元分析结果表明，优化方案2轮胎的1#和2#带束层受力较均匀，0°带束层有较大的箍紧胎肩的张力。成品性能试验结果表明，与原轮胎相比，优化轮胎的接地印痕明显改善，耐久性能大幅提高。 |
| 英文摘要: |
| The design on belt angle of 295/75R22.5 truck and bus radial tire was optimized using finite element analysis of two-dimension inflation and it was verified by test of the finished tire.The FEA results showed that the stress distribution on the 1# and 2# belts of optimized scheme 2 tire was uniform and the 0° belt had a larger hoop tension on tire shoulder.The experimental testing results on finished tire showed that，compared with the original tire，the footprint of optimized tire was improved，and endurance performance increased significantly. |
