efficiency of force vibroisolation
Opis:: In this paper, the force efficiency of the WoSSO vibroisolation in reducing forces transferred into the base by machines and the equipment working at low operating frequencies has been discussed. To assess that efficiency, a strongly non-linear mathematical model using Lagrange equations of the second kind has been developed. That model takes into account the specific design of the vibroisolator. The mathematical model has been solved using s digital simulation method, by developing a special computer program in the MATLAB/simulink environment. The efficiency of the force vibroisolation has been determined for a specific application of the WoSSO vibroisolator. The calculated force vibroisolation efficiency exceeds 32.

Opis:: The main aim of this study is to present an energy comparison of two human physical models taking into account hand-arm vibrations, which are based on the power distribution in their dynamic structure. The method used in the study takes advantage of a close relationship between the dynamics of the systems and energy-related phenomena that occur within them. The energy comparison of the two human physical models required construction of energy models of a Human-Tool system and finding their solutions. For this purpose, programs have been developed using the MATLAB/simulink software to simulate power distribution in the systems. The simulation revealed a discrepancy between the two models in terms of three types of powers and globally in the system as a whole.

Tytuł:: 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

Opis:: 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.
