Abstract
The biodynamics of the hand-arm system is an important part of the foundation for understanding hand-transmitted vibration exposure and its health effects. The objective of this study is to determine how the biodynamic response (BR) can be accurately measured. A modeling analysis of typical BR measurement systems coupled with a hand-arm system was performed. A new model of the hand-arm system was used. The flexibility of the handle and its fixture mounting were taken into account. This study found that the locations of the force sensors and accelerometer in the instrumented handle are critical to assuring the accuracy of the measurement. To increase the accuracy of the measurement at high frequencies, it is essential to maximize the stiffness of the instrumented handle.
