    Opis:
    The study relates to the phenomenon of power distribution in mechanical systems equipped with a dynamic vibration absorber. It is one of the methods of eliminating vibrations in a mechanical system, which stabilises its operation. This solution helps to reduce dynamic stress in subsystems of a vehicle's suspension or stabilise the motion of flying machines, such as helicopters. The article describes the phenomenon of power distribution of structural forces, which has not been described so far. The phenomenon reveals the power distribution in a dynamic structure of a system of interest and can be used to determine the rate of energy flow as a function of the dynamic state resulting from the selection of dynamic parameters of the vibration absorber. The energy analysis applied in the study is based on an energy-based optimization method of adjusting the dynamic vibration absorber to the main mechanical system without changing its dynamic parameters, as is the case, for example, in turbine rotor balancing.

    Opis:
    This article is a continuation of the article entitled „A comparison of human physical models used in the ISO 10068:2012 standard based on power distribution – Part 1” [5], which presented a method of energybased assessment of two human physical models. The first article revealed a discrepancy between the models in terms of three types of power and the total power. The focus of the present study was to determine the order of energy inputs in the dynamic structure and link different types of power to potential threats they pose to human health. Additionally, differences between the models were discussed.

    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 continues the analysis presented in the article „Power distribution in anti-vibration gloves” [6], which described the approach adopted to construct an energy model of the Human – Glove – Tool system (H – G – T). The outcome of the analysis was the power distribution calculated only for the anti-vibration glove. This article continues the energy analysis for another subsystem of the H – G – T system – the human physical model. The energy method was also used to calculate the power distribution in its dynamic structure in order to account for interactions between the elements of the H – G – T system. The results obtained in the study indicate that the power distribution in the human physical model and in the glove model is completely different.

    Opis:
    The article analyses power distribution in an anti-vibration glove. The glove of interest was modelled in a biodynamic model of the Human – Glove – Tool system. The model was a combination of the human model and the glove model specified in the ISO 10068:2012 standard and the model of the vibration tool. To determine the power distribution in the glove, its energy model was developed. The power distribution in the model was determined using numerical simulation in order to show how power was distributed in the dynamic structure of the anti-vibration glove. Three kinds of powers were distinguished, which are related to forces of inertia, dissipation and elasticity. It turned out that out of the three kinds of powers identified in the anti-vibration glove, only one is dominant: namely the power of dissipation.

    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.
