中文摘要: |
通过选择适宜测试点位置、车辆速度和测试路面以及软件测试系统,研究轮胎车内噪声评价方法。依据轮胎车内噪声分布特点,对车内测试声音的频谱进行分段分析,提出轮胎车内噪声评价指数(TICNI)的评价方法,并将TICNI与主观评价结果进行对比。结果表明,TICNI评价指数与主观评价结果具有较好的相关性。 |
英文摘要: |
The evaluation method of in-car noise induced by tire was investigated by selection of appropriate test position, vehicle speed, test road and software system. According to the in-car noise distribution, the frequency spectrum was divided into different sections, and the in-car noise index(TICNI) was proposed for noise evaluation and compared to subjective evaluation result. The test results showed that TICNI and subjective evaluation result had good correlativity. |
