A parameter study on measuring hand-arm vibrations of an impulsive vibrating tool applying the international standard
* Presenting author
In daily life, many activities expose us to hand-arm vibrations (HAV). The characteristics, such as frequency components or level, of these vibrations vary substantially. At high levels some can cause changes to the hand-arm system, which are grouped under the term hand-arm vibration syndrome (HAVS). Hence, there are multiple standards on the subject of measuring, evaluating and simulating HAV. In these, many cases are covered with specific instructions, but not all. This leaves leeway in measurements. Additionally, previous studies have shown largely varying results, some even on the same device. As the assessment of the risks for the hand-arm system depends both on accurate measurements and knowledge of the influences here-on. The leeway left in the specifications in the standards may be at least part of the origin of the variance in the measured results. In a measurement and comparison of previous studies, influencing factors are to be determined. The goal is an appraisal of the extent of their effect.
