Abstract

The cost and complexity of commercially available whole-body vibration measurement devices is a barrier to the systematic collection of the information required to manage this hazard. The potential for a consumer electronic device to be used to estimate whole-body vibration was assessed by collecting 58 simultaneous pairs of acceleration measurements in three dimensions from a fifth-generation iPod Touch and gold standard whole-body vibration measurement devices, while a range of heavy mining equipment was operated at three surface coal mines. The results suggest that accelerometer data gathered from a consumer electronic device are able to be used to measure whole-body vibration amplitude with 95% confidence of ±0.06 m s(-2) root mean square for the vertical direction (1.96 × standard deviation of the constant error).

摘要

市售全身振动测量设备的成本和复杂性阻碍了系统收集管理这种危害所需的信息。通过在三个露天煤矿操作一系列重型采矿设备时，从一台第五代iPod Touch和黄金标准全身振动测量设备同步采集58对三维加速度测量数据，评估了使用消费电子设备估计全身振动的可能性。结果表明，从消费电子设备收集的加速度计数据能够用于测量全身振动幅度，垂直方向的均方根误差为±0.06 m s(-2)，置信度为95%（常数误差标准差的1.96倍）。
