Prolonged and intensive vibration exposures during the grinding of handheld workpieces may cause hand-arm vibration syndrome. The objectives of this study are to develop an on-the-hand method for evaluating vibration-reducing (VR) gloves, and to determine whether VR gloves can significantly reduce the vibration exposures. A worker holding and pressing a typical workpiece (golf club head) against a grinding wheel or belt in order to shape the workpiece was simulated, and the input vibration and those on the workpiece and hand-arm system were measured. Ten human subjects participated in the experiment. The results demonstrate that VR gloves significantly reduced the vibrations at the palm, hand dorsum, and wrist. The grinding interface condition and hand feed force did not substantially affect glove effectiveness. The use of gloves slightly increased the workpiece resonant response, but the resonant response did not significantly affect glove effectiveness. This study concluded that the use of VR gloves can help control vibration exposures of workers performing grinding of handheld workpieces.

手持式工件磨削过程中长时间和强烈的振动暴露可能会导致手臂振动综合症。本研究的目的是开发一种用于评估减振 (VR) 手套的手上方法，并确定 VR 手套是否可以显着减少振动暴露。模拟一名工人将典型工件（高尔夫球杆头）压在砂轮或砂带上以塑造工件，并测量输入振动以及工件和手臂系统上的振动。十名人类受试者参与了实验。结果表明，VR 手套显着降低了手掌、手背和手腕的振动。研磨界面条件和手动进给力基本上不影响手套的有效性。手套的使用略微增加了工件共振响应，但共振响应并没有显着影响手套的有效性。这项研究得出的结论是，使用 VR 手套可以帮助控制工人进行手持工件磨削时的振动暴露。
