| 中文摘要: |
| 研究室外轮胎噪声测试结果与轮胎模态及室内噪声测试结果的相关性，并依据其进行轮胎噪声结构设计优化。试验结果表明：轮胎室内噪声测试结果与轮胎室外噪声测试结果之间具有相关性，可先通过室内噪声试验进行轮胎结构方案优选，以缩短轮胎开发时间及节约成本；轮胎模态与空腔共鸣噪声存在相关性，模态出现峰值的情况下空腔共鸣噪声也明显偏大；通过充入氦气及贴吸音海棉的方式，可以明显减小轮胎空腔共鸣噪声。 |
| 英文摘要: |
| The correlation between the tire outdoor noise test results and tire modal and indoor noise test results were investigated，and the tire noise structure design was optimized based on it.The test results showed that there was a correlation between the tire indoor noise test results and tire outdoor noise test results.The indoor noise test could be used to optimize the tire structure design first to shorten the development time of the tire and save the cost.The tire modal and cavity resonance noise were correlated.When the modal had a peak，the cavity resonance noise was obviously large.By filling helium gas and attaching sound-absorbing sponge，the tire cavity resonance noise could be significantly reduced. |
