A comparison of human physical models used in the ISO 10068:2012 standard based on power distribution. Part 1

The study analyses differences in the flow of energy for two human physical models specified in the ISO 10068:2012 standard. For this purpose, two mathematical models of the Human–Tool system in question were developed using the Lagrange equation of the second kind. Corresponding energy models were then created for each mathematical model and tested by means of digital simulation in the MATLAB/Simulink environment. The study revealed a discrepancy between the models in terms of different types of power and in the total power.
