| 通过有限元仿真分析研究载重子午线轮胎结构对振动噪声的影响。建立了轮胎有限元分析模型并对其合理性进行了试验验证；在原轮胎结构的基础上，对带束层结构和胎面花纹进行优化设计，利用声学仿真软件进行仿真分析，得到了轮胎各设计方案的振动噪声。结果表明，带束层结构和胎面花纹设计均会影响轮胎振动噪声，带束层结构和胎面花纹优化后最大降噪量分别达到3.09和3.9 dB。 |
| 英文摘要: |
| The influence of structural designs on the vibration noise of the truck and bus radial tire was studied by finite element simulation analysis. A tire finite element analysis model was established and verified by experimental test，and the belt structure and tread pattern were optimized based on the original tire structure. The vibration noise of the tire with different design was obtained by using acoustic simulation software. The results showed that the design of the belt structure and tread pattern had significant influence on vibration noise of the tire. The maximum noise reductions obtained by belt structure optimization and tread pattern optimization were 3.09 and 3.9 dB，respectively. |
