Opis:
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.

Opis:
The article is an introduction to the assessment of the effectiveness of anti-vibration gloves. The assessment was conducted for a specific glove. The impact of the glove was taken into account in a model of the biodynamic system consisting of the human operator, the anti-vibration glove and the hand-held power tool. The synthetic model was created by integrating the physical model of the human body and the glove model specified in the International Standard ISO 10068:2012 with a model of an electric angle grinder. The first part of the study describes an alternative model of the glove, developed on the basis of experimental data. The article also presents a description of dynamic and energy models for analyzing dynamic structures of the biomechanical system. Results obtained at this stage are used to analyse and interpret the observed phenomena and to compare methods of assessing the effectiveness of anti-vibration gloves, which are discussed in detail in the second part.

Opis:
The article is the second part of the article entitled “Assessment of the effectiveness of anti-vibration gloves. A comparison of the conventional and energy method. Introduction - part one” [4], which presents the assumptions and the construction of models of the biodynamic system consisting of the human operator, the anti-vibration glove and the hand-held power tool. The second part is devoted to a comparative analysis and interpretation of results obtained by means of the two methods. The analysis reveals a positive effect of the anti-vibration glove as a personal protective equipment, which reduces the operator’s exposure to vibrations generated by the angle grinder. However, the effectiveness of the glove was assessed differently by the conventional or the energy method. It was also found that the energy method was a better tool for analyzing the impact of vibrations at different phases of the tool’s operation.
