摘　　要：目的探讨气动扳手使用中手传振动测量的影响因素。方法于2016年5月,在某汽车装配厂以3名组装作业人员为研究对象,依据手传振动测量标准ISO5349,按照正交试验方案设计这些影响因素,连续测量、记录不同因素条件下的加速度有效值(a_(hw))。结果测量时间、测量位置、作业人员、加速度计轴向这4项因素的极差(R)依次为:59.5、62.4、52.1和6.80。显著性检验显示,测量位置为高度显著(临界值F_(0.01)=5.42),测量时间、作业人员因素为显著(临界值分别为F_(0.05)=3.33、F_(0.1)=2.50)。结论测量位置是手传振动测量的主要不确定影响因素,测量时间和作业人员是潜在影响因素。Objective To investigate the four influences of hand-transmitted vibration measurements by the orthogonal experimental in air wrench.Methods 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.Results 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（F0.01=5.42）,measurement time and operate staff are the ordinary degree（F0.05=3.33,F0.1=2.50）.Conclusion The adaptor location was the main uncertain influences factors on HAV measurements,the measurement time and operator staff were the potential influences factor.
