This paper presents experimental research evaluation of the vibration exposure for the health risk prediction during vehicle operation. The vibration measurements were carried out on a recreational vehicle and two types of agricultural tractors. The vibration levels were measured for different surfaces and vehicle speed conditions. Based on the analysis of the results in the small agricultural tractor operated in the workplace (frameworks), Sed exceeded 0.80 MPa by ISO2631-5:2004, and Av exceeded 0.89 m/s(2) by ISO2631-1:1997. That means that operators driving small agricultural tractors more than 8 h a day have a high probability of adverse health effects. However, the exposure value for the recreational vehicle had Sed < 0.5 MPa by ISO2631-5:2004 and Av < 0.5 m/s(2) by ISO2631-1:1997 on highways and local roads. That means Recreational Vehicle operators driving more than 8 h a day, have a low probability of adverse health effects. Also, for the recreational vehicle, vibration was taken at different speeds (40-60 km/h, 80 km/h, 100-120 km/h). However, the speed change did not appear to affect the vibration dose variation while driving a vehicle on the highway and road. Finally, the health effect index of ISO2631-5:2004 are almost the same as assessment of health effect by ISO2631-1:1997.
本文介绍了车辆运行过程中振动暴露对健康风险预测的实验研究评估。在休闲车和两种类型的农用拖拉机上进行了振动测量。测量了不同表面和车辆速度条件下的振动水平。基于在工作场所（框架）中运行的小型农用拖拉机的结果分析，Sed 超过了 ISO2631-5:2004 的 0.80 MPa，Av 超过了 ISO2631-1:1997 的 0.89 m/s(2)。这意味着每天驾驶小型农用拖拉机超过 8 小时的操作员有很高的健康影响的可能性。然而，在高速公路和地方道路上，休闲车的暴露值为 Sed < 0.5 MPa（ISO2631-5:2004）和 Av < 0.5 m/s(2)（ISO2631-1:1997）。这意味着每天驾驶超过 8 小时的休闲车操作员，健康影响的可能性较低。此外，对于休闲车，在不同速度（40-60 公里/小时、80 公里/小时、100-120 公里/小时）下进行了振动测量。然而，在高速公路和道路上行驶时，速度变化似乎并没有影响振动剂量的变化。最后，ISO2631-5:2004 的健康影响指数几乎与 ISO2631-1:1997 的健康影响评估相同。
