Evaluation of hand-arm vibration reducing effect of anti-vibration glove

Junya TATSUNO*1, Setsuo MAEDA*2, Kazuki YOKOTA*3 and Yuichiro TAIRA*3

Many kinds of the anti-vibration glove have been developed for reducing hand-arm vibration during the operation with vibration tools. International standard ISO 10819 evaluates the physical effect of gloves’ vibration transmissibility but not evaluates the physiological effect of human hands. Thus, in this paper, we proposed the evaluation using the temporary threshold shift of vibrotactile perception threshold to evaluate the hand-arm vibration reducing effect of anti-vibration glove. We performed the experiments where subjects were exposed to hand-arm vibration under the three glove conditions; two kinds of gloves and barehanded. As a result, we could confirm wearing the anti-vibration gloves provides positive effects for human hands physiologically and the proposed method might be effective for evaluation of the hand-arm vibration reducing effect of anti-vibration glove.
