| 中文摘要: |
| 利用半消声试验室和高速均匀性试验机对4条225/60R18 100T轮胎空腔共鸣噪声进行研究。结果表明：4条轮胎在速度为90～120 km·h-1时存在空腔共鸣噪声；轮胎第16阶次噪声频率段和第16阶径向波动力谐波频率段与噪声各切片分析中的频率段（190～240 Hz）基本一致；改善轮胎第16阶的径向波动力会降低轮胎振动，进而降低噪声；轮胎纵向波动力幅值对噪声影响较小，可以不考虑其对噪声产生的影响。借助半消声试验室和高速均匀性试验机，利用高速均匀谐波力和噪声切片理论相结合的测试方法对轮胎空腔共鸣噪声的室内研究具有一定的指导意义。 |
| 英文摘要: |
| The resonant noise in the cavities of four 225/60R18 100T tires was studied using a semi anechoic laboratory and a high-speed uniformity testing machine.The results showed that there was cavity resonance noise in the four tires at speeds of 90～120 km · h-1.The 16th order noise frequency band and the 16th order radial force variation harmonic frequency band of tires were basically consistent with the frequency band（190～240 Hz） in the noise slice analysis.Improving the 16th order radial force variation of tires would reduce vibration of tires，thereby reducing the noise.The amplitude of tangential force variation of tires had a relatively small impact on tire noise，and its impact on noise could be disregarded.The method that using a semi anechoic laboratory and a high-speed uniformity testing machine，combined with high-speed uniform harmonic force and noise slicing theory，had certain guiding significance for indoor research on resonant noise in tire cavity. |
