| 摘 要： | 从动力学角度研究不同开口方向的花纹沟的噪声差别。分析及仿真试验结果表明,逆向沟口喷出的气团除了原有速度外,还加入了一个向前的车速的分量,而顺向沟喷口气团速度减去一个分量速度;根据推导的经验公式得出逆向花纹沟的噪声比顺向沟大3 dB左右。

| Abstract: | The effect of the open end directions on the noises from tread grooves was investigated from the point of view of dynamics.The results of simulation test and analysis showed that the speed of air mass jetted from the open end of backward groove was equal to the original speed plus a forward component of vehicle speed,and that of forward groove was equal to the original speed minus a forward component of vehicle speed.It was found from the experimental formula that the noise from the backward groove was 3 dB greater than that from the forward groove. |
