The vibration levels of 87 axes in 29 conventional vehicles were measured, recorded, and analyzed. The mean deviation of the overall frequency-weighted vibration levels (Lw) and the greatest single one-third octave band frequency-weighted vibration levels (Lwi-max) in corresponding axes were statistically calculated. The results showed that the vehicle vibrations were broad-band vibrations. The mean deviation of Lw - Lwi-max is 6 dB. This article suggests a 6 dB value as an appropriate adjustment value for evaluating broad-band whole-body vibrations of vehicles when using the most sensitive limits given in International Organization for Standardization document 2631/1.
对29辆传统车辆的87根轴的振动水平进行了测量、记录和分析。统计计算了相应轴上整体频率加权振动水平(Lw)的平均偏差以及最大的单个三分之一倍频程带频率加权振动水平(Lwi-max)。结果表明,车辆振动为宽带振动。Lw - Lwi-max的平均偏差为6分贝。本文建议,在使用国际标准化组织2631/1文件中给出的最敏感限值时,将6分贝的值作为评估车辆宽带全身振动的适当调整值。
