To investigate the four influences of hand-transmitted vibration measurements by the orthogonal experimental in air wrench.
With reference to the measurement standard for hand-transmitted vibration ISO 5349 Mechanical vibration-Measurement and evaluation of human exposure to hand-transmitted vibrationPart1:General requirements and Mechanical vibration-Measurement and evaluation of human expusure to hand-transmitted vibration-Part 2:Practical guidance for measurement at the workplace, the domestic AWA5936 hand-transmitted vibration measuring instrument was used to measure hand-transmitted vibration in 3 workers for an automobile plant in production chain field for the orthogonal continuously experimental in May, 2016, and data were recorded and compared. 3 the domestic AWA5936 hand-transmitted vibration measuring instrumencases of hand vibration workers as research object, based on ISO5349. The determinate influences factors were adapter locations, measurement time, hand vibration workers and accelerator axis.
The range and variance analysis of adaptor location, measurement time, operate staff and accelerator axis were 59. 5, 62. 4, 52. 1 and 6. 80. The significance test, the factor of the adapter location is the high degree(F_(0. 01)=5. 42), measurement time and operate staff are the ordinary degree(F_(0. 05)=3. 33, F_(0. 1)=2. 50).
The adaptor location was the main uncertain influences factors on HAV measurements, the measurement time and operator staff were the potential influences factor.
通过正交试验研究气动扳手手传振动测量的四个影响因素。
参照手传振动测量标准ISO 5349《机械振动——人体暴露于手传振动的测量与评价 第1部分：一般要求》和《机械振动——人体暴露于手传振动的测量与评价 第2部分：工作场所测量实用指南》，于2016年5月使用国产AWA5936型手传振动测量仪，对某汽车厂生产链现场的3名工人进行手传振动的正交连续试验，记录并比较数据。以3例手部振动工人的国产AWA5936型手传振动测量仪测量情况为研究对象，依据ISO5349标准。确定的影响因素为转接器位置、测量时间、手部振动工人和油门轴。
转接器位置、测量时间、操作人员和油门轴的极差及方差分析分别为59.5、62.4、52.1和6.80。显著性检验结果显示，转接器位置因素为高度显著（F_(0.01)=5.42），测量时间和操作人员为一般显著（F_(0.05)=3.33，F_(0.1)=2.50）。
转接器位置是手传振动测量的主要不确定影响因素，测量时间和操作人员是潜在影响因素。
