Differences in energy flow in three directions in Human-Tool biomechanical systems based on spatial human physical models specified in the ISO 10068:2012 standard

Marian Witalis Dobry, Tomasz Hermann
The article presents the differences in energy flow for two human physical models from ISO 10068:2012. The models are compared on the basis of a numerical simulation of energy flow implemented with MATLAB/simulink software. For purposes of comparison, the dynamics of the two Human-Tool systems is mathematically modelled and then used to derive their energy models. The model dynamic structures are fully specified in order to determine and compare three kinds of powers. The study revealed differences between the model characteristics when analysed along different directions of vibrations and as a whole.
