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 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:: This paper presents an analysis of the natural frequency and mode shapes of the arm and the working tip of the da Vinci robot, which is used in various types of surgical procedures. The survey was conducted using Autodesk Fusion 360. Using the da Vinci robot's construction data, a model was designed taking into account the characteristic dimensions and materials used. The obtained shapes of vibrations for natural frequencies allowed us to predict the influence of resonance phenomenon on the manipulator's arm. The movement of the tool along the wrong track, caused by an increase in vibration amplitude, may adversely affect the operation of the device. The results of the conducted research, therefore, provide information for which natural frequencies the values of these amplitudes increase.
