A comparison of human physical models based on the distribution of power in a dynamic structure in the case of hand-arm vibrations

Marian Witalis Dobry, Tomasz Hermann
The main aim of this study is to present an energy comparison of two human physical models taking into account hand-arm vibrations, which are based on the power distribution in their dynamic structure. The method used in the study takes advantage of a close relationship between the dynamics of the systems and energy-related phenomena that occur within them. The energy comparison of the two human physical models required construction of energy models of a Human-Tool system and finding their solutions. For this purpose, programs have been developed using the MATLAB/simulink software to simulate power distribution in the systems. The simulation revealed a discrepancy between the two models in terms of three types of powers and globally in the system as a whole.
