Abstract

The objective of this study was to analyse the effects of grip force on the upper arm under both continuous and shock vibration. A 5 DOF model was used to simulate the biodynamics response of the system. Measured data from previous studies have been used as parameters for the analytical model. The results show that the responses predicted from the model agree reasonably well with the measured data. The variations in the model parameters under different grip forces are further discussed in view of the biological and mechanical system behaviour. The presented study could be useful for design and assessment of vibration handheld tools.
