Abstract Approximately 1.6 million commercial construction workers in the US use rotary hammer drills for drilling into concrete to insert anchor bolts or rebar. The exposure to vibration may lead to hand-arm vibration syndrome and other musculoskeletal disorders depending on handle vibration acceleration level, hand grip force, and duration of exposure. There is little information on the relationship between feed force (FF), e.g., the push force applied by the worker, and handle vibration. A robotic test bench for rotary hammer drills was used to evaluate the effects of different FF on handle vibration and productivity (e.g., penetration rate and holes drilled). Increasing FF from 95 to 163 N was associated with an increase in total weighted handle vibration (ahv) of 7.2–8.5 m/s2 (slope, p

R2：钻入混凝土：进给力对手柄振动和生产率的影响

摘要 美国大约有 160 万商业建筑工人使用电锤钻在混凝土中钻孔以插入地脚螺栓或钢筋。根据手柄振动加速度水平、手握力和暴露时间，暴露于振动中可能导致手臂振动综合征和其他肌肉骨骼疾病。关于进给力 (FF)（例如工人施加的推力）与手柄振动之间关系的信息很少。用于电锤钻的机器人测试台用于评估不同 FF 对手柄振动和生产率（例如，穿透率和钻孔）的影响。将 FF 从 95 N 增加到 163 N 与总加权手柄振动 (ahv) 增加 7.2–8.5 m/s2（斜率，p
