Whole body vibration (WBV) was measured on eight surface haulage trucks in three size classes (35, 100, 150ton haul capacities). Vibration was measured at the seat/operator interface in accordance with the ISO 2631-1 standard during 1h of normal operation. Highest acceleration readings were observed in the z-axis (vertical). Estimated equivalent daily exposure values in the range of 0.44-0.82 ms(-2) were observed using the frequency-weighted r.m.s method and 8.7-16.4ms(-1.75) using the vibration dose value method. Assessment was carried out using ISO 2631-1 and 2631-5. Operators of surface haulage trucks are regularly exposed to WBV levels that exceed safety limits as dictated by the ISO 2631-1 standard. However, according to ISO 2631-5 the probability of an adverse health effect remains low. These findings confirm an apparent disagreement between the two analysis methods.
全身振动(WBV)在三个尺寸等级(35、100、150 吨运输能力)的八辆表面运输卡车中进行了测量。根据 ISO 2631-1 标准,在 1 小时的正常运行期间,在座椅/操作员接口处测量了振动。在 z 轴(垂直)上观察到最高的加速度读数。使用频率加权 r.m.s 方法观察到的等效日暴露值在 0.44-0.82 ms(-2)范围内,使用振动剂量值方法观察到的等效日暴露值在 8.7-16.4ms(-1.75)范围内。评估使用 ISO 2631-1 和 ISO 2631-5 进行。表面运输卡车的操作员经常暴露于超过 ISO 2631-1 标准规定的安全限制的 WBV 水平。然而,根据 ISO 2631-5,不良健康影响的可能性仍然较低。这些发现证实了两种分析方法之间明显存在分歧。
