| 中文摘要: |
| 汽车后桥驱动齿轮是汽车驱动桥的主要部件,噪声是其主要指标之一。以广东某汽车后桥齿轮厂的微型汽车后桥锥齿轮为噪声源,采集其稳态运行情况下的噪声作为研究对象,以成对比较法进行噪声评价训练,采用等级评分法进行噪声的主观评价实验,结合噪声样本的客观参数进行主客观相关分析,说明在等声压级的齿轮噪声中,响度值越大的,人们对其偏好性越低,因此除积极采取措施降低齿轮声压级以外,降低响度值亦是改善价齿轮噪声的重要途径。 |
| 英文摘要: |
| The rear axle driving gear is the main component of the vehicle driving axle,and noise is one of the main specifications for it.In this paper,the minicar’s rear axle bevel gear produced by a factory in Guangdong is taken as a noise source,and the noise generated under the steady-state operation is the object of the experimental study,the paired comparison method is used for noise evaluation training and the scoring method for noise subjective evaluation experiments.Combining the objective noise parameters to conduct the subjective and objective sample correlation analysis shows that for the equal SPL gear noise,the greater the loudness value,the lower the people’s preference ex-tent.So,in addition to actively taking measures to reduce gear sound pressure level,reducing the loudness value is also an important approach to improving gear noise. |
