介绍轮胎/路面噪声测定及数据分析方法。轮胎/路面噪声测量方法主要有滑行法、转鼓法和拖车法,双话筒测试法、定点测试法及扫描法更实用;提出了声压级、声强级和声功率级的转换处理简易方法,去掉最大值和最小值,以减小干扰误差,做为噪声评判的依据。
The measurement and analysis method of tire/pavement noise were described. The main measuring methods of tire/pavement noise were sliding method, drum method and trailing method. For the testing methods, double sensor testing, stable spot testing and scan testing were more applied. The convert method among sound pressure level, sound intensity level and sound power level was proposed as basis of noise evaluation, which deleted the maximum value and minimal value to reduce error.
