To assure the correct dynamic behavior and fatigue life of dynamically exposed products proper dynamic tests must be planned at the virtual stage as well as at the prototype stage on a product. In this research the mentioned was done in the case of pressure sensor glow plug, designed by big Slovenian export company.

COBISS.SI-ID: 13817883The research is focused on the analysis of the complex structures. It contains the theoretical and experimental comparison of the classic vs. strain Experimental Modal Analysis (EMA). Compared to the classic EMA, the strain EMA has benefits and drawbacks. One of its drawbacks is that it does not enable mass normalization of the identified mode shapes. A new approach to mass normalization is presented, based on the sensitivity analysis. The research also is focused on substructure identification that is based on the identification of the coupling forces with the strain-response measurements.

COBISS.SI-ID: 13693467This research presents identification of vibroisolation parameters for use in numerical prediction of its performance. Different simple single-degree-of-freedom (SDOF) systems are used to derive equations for identification of parameters of vibroisolation material. Identified frequency-dependent parameters, frequency dependent Youngʼs modulus and damping factor, are further used in finite-element model. With this we are able to effectively predict the performance of vibroisolation even on more demanding geometry of vibroisolation material. Numerical prediction of vibroisolation performance was calculated on real complex structure and compared with experiment.
