| 中文摘要: |
| 在分析轮胎/道路噪声发声机理的基础上，建立了轮胎/道路噪声各主要噪声源的发声模型，并将轮胎和道路的噪声波合成得到总的时域波形，通过离散傅立叶变换得到轮胎/道路噪声的频谱，得出了时域耦合因子行阵和频域耦合因子行阵，为低噪声轮胎花纹和低噪声路面的研究和设计提供了理论依据和技术路线。 |
| 英文摘要: |
| The sound-generating models for the main sources of tire/road noise were established based on analysis of the sound generating mechanisms of tire/road noise， and the total time-domain wave was obtained by combining the noise waves of the tire and road. By DFT method， the frequency spectrum of tire/road noise， the coupling factor row matrices for time domain and frequency-domain were obtained，which proposed the criteria and technical line for research or design of tire tread patterns and road with low noise. |
