室内转鼓法中不同转鼓面对于轮胎噪声影响分析
|
摘要
通过采用室内转鼓法对在不同转鼓表面工况下的轮胎噪声进行测试,并对相同工况下不同实验室的测试结果进行对比分析。结果表明,在不同转鼓表面所测得的轮胎噪声在频谱上具有显著的差异,并且轮胎噪声的大小与转鼓面的粗糙程度正相关。在ISO 10844鼓面与钢制光滑鼓面工况下,轮胎噪声随着速度的增加呈现明显的线性增长趋势。在ISO 10844鼓面工况下不同轮胎的声功率差值在各频带内基本一致,并且表现出明显的随频率变化的趋势,说明该转鼓面的测试数据具有良好的稳定性。
The noise of tires is tested by indoor laboratory drum method on different drum surfaces, and the results tested in different laboratory are compared and analyzed. According to the results, tire noise tested on different drum surfaces has significant differences in spectrum. Meanwhile, the tire noise level has positive relationship with the roughness of the drum surface. Tire noise presents a linear growth trend as the speed increased, under the condition of both ISO 10844 drum surface and smooth drum surface. The sound power difference among different tires in the ISO 10844 drum condition is basically the same in each frequency band, and shows a clear trend in spectrum, that indicates the test data of the drum head has good stability.
