Tungsten Bucking Bars for Riveting Task

Recently, bucking bars made of tungsten have been utilized for some riveting tasks at a local
aircraft manufacturer, where subjective reports from the employees suggested less vibration was
transmitted to the hands. However, since the tungsten bars weigh approximately 2.3 times more
than the steel bucking bars of the same size and shape, the company was reluctant to implement
tungsten bucking bars on a full scale. While the increased mass of the tungsten bar may be an
advantage as far as dampening the vibration, the effect on the hand grip exertion levels was
unknown. Therefore, the overall objective of this study was to perform a field evaluation to quantify
and compare the vibration transmission and grip muscle activity characteristics when using bucking bars of the same size and shape, but made of different materials.
