摘　　要： 目的评价高尔夫球头打磨作业工人手传振动的接触情况。方法采用判断抽样方法,选择某运动器材厂高尔夫球头打磨岗位为研究对象,测量66个打磨岗位作业工人手传振动接触水平,识别手传振动危害的关键控制点,进行手传振动危害分级。结果该运动器材厂高尔夫球头打磨岗位4 h等能量频率计权振动加速度[ahw(4)]中位数(M)为4.21 m/s2,打磨岗位ahw(4)超标率为50.0%(33/66)。粗磨作业岗位a(hw(4)高于细磨作业岗位(M:5.50 vs3.94 m/s2,P<0.05)。粗磨作业和细磨作业中,不同球头打磨岗位ahw(4)由高到低依次为空心钛合金球头、空心不锈钢球头、实心不锈钢球头(粗磨作业M:7.47 vs 4.43 vs 3.11 m/s2,P<0.01;细磨作业M:5.24 vs 4.21 vs 2.93 m/s2,P<0.01)。对于空心钛合金球头打磨岗位,粗磨作业岗位ahw(4)高于细磨作业岗位(M:7.47 vs 5.24 m/s2,P<0.01)。粗磨作业岗位特别是空心不锈钢球头和空心钛合金球头打磨岗位是手传振动危害的关键控制点。66个打磨岗位手传振动危害分级为0、Ⅰ、Ⅱ、Ⅲ级危害的岗位分别占3.0%、47.0%、40.9%和9.1%,Ⅱ级及以上危害者占50.0%(33/66)。结论高尔夫球头打磨作业工人手传振动职业接触水平高,超标严重,存在较高的职业健康风险。 Objective To evaluate the exposure status of hand-transmitted vibration(HTV)in golf ball head grinding workers.Methods The golf ball head grinding positions in a sports equipment factory were selected as the research subjects by the judgement sampling method.The HTV exposure level of the workers in 66 grinding positions was measured,the key control points for HTV hazards were identified,and the damage of HTV was classified.Results The median(M)of 4 hours energy equivalent frequency-weighted acceleration to vibration[ahw(4)]of grinding positions in this sports equipment factory was 4.21 m/s2,and the ahw(4) over standard rate was 50.0%(33/66).The ahw(4) of rough grinding positions was higher than that of fine grinding positions(M:5.50 v.s 3.94 m/s2,P<0.05).In both rough grinding positions and fine grinding positions,the ahw(4) of different ball head grinding types from high to low were hollow titanium alloy ball heads, hollow stainless steel ball heads,and solid stainless steel ball heads(rough grinding positions M:7.41 vs4.43 vs 3.11 m/s2,P<0.01;fine grinding p ositions M:5.24 vs 4.21 vs 2.93 m/s2,P<0.01).For the hollow titanium alloy ball head grinding positions,the ahw(4) of rough grinding was higher than that of fine grinding(M:7.47 vs 5.24 m/s2,P<0.01).Rough grinding positions,especially hollow stainless steel ball heads and hollow titanium alloy ball head grinding positions were key control points for HTV hazards.In the 66 grinding positions,the HTV hazards were classified as grade 0,Ⅰ,Ⅱ,and Ⅲ in the grinding positions accounted for 3.0%,47.0%,40.9%,and 9.1%,respectively,and those with grade Ⅱ and above were 50.0%(33/66). Conclusion The exposure level of HTV in golf ball head grinding workers is high,with a trend of exceeding the standard.The golf ball head grinding workers have a high occupational health risk.
