Abstract
The research project of the optimisation of Automatic Electrical Safety Fuse includes the development of the automatic electrical safety fuse whose propose is to safeguard electrical devices from electrical overloading and short circuit. On the basis of our original designs of the mechanisms operating on the principle of through-snap system, the geometric optimisation of the elements from which the automatic electrical safety fuse is put together was developed. We achieved a smaller swich-off force on the switching arm, which makes posible to use the automatic electrical safety fuse for working with different electric current. The research project of development of methods for measuring mechanical properties of materials by load-depth sensing indentation includes using the previously developed numerical models for simulation of instrumented indentation experiments were utilized in development of methods for determining mechanical properties of metals, such as hardness, modulus, yield stress, work-hardening coefficient, and the true stress-strain curve. A series of simulations were performed to determine the correlation between modulus and the indentation load and depth data. These results were then used in development of a methodology for determining the modulus from the data measured by instrumented indentation. A similar approach was used in the development of the method for determining the yield stress The research of non-linear vibrations of the real dynamical systems includes analytical, numerical and experimental modelling of the real non-linear dynamical processes. They include elements of vibroisolation as well as cutting process. Special attention will be put into better understanding of dry friction phenomenon in non-linear oscillations. Analyses of time series will include estimation of several measures in reconstructed phase space and estimation of bispectra and their normalised version bicoherences. At the end, the decomposition of several noise sources of the DC electric motors will be made. Considerable attention is devoted also to the investigation of the inverse problem of the second kind which, when it is applied in connection with the identification of material physical properties, become actually a material characterization problem. A numerical system is developed which enables more efficient computer aided identification of complex material relationships even when strictness of the conditions that are imposed in an experiment are considerably loosened. The computational methodology relies on the comparison between the real response of an experiment and a computed response from a numerical model, the latter being in turn improved by a corresponding adjustment of the numerical model. Within the sensitivity analysis investigations applied to elastic-plastic problems with material models based on co-rotational tensors expressions are deduced that enable direct computation of the components of rotational tensor in the polar decomposition of the deformation gradient.
