Abstract
Prisotnost udarnih obremenitev povzroči napako pri oceni vibracijske poškodovanosti v frekvenčni domeni. Bistvo magistrske naloge je primerjava ocen oz. odstopanja med vibracijsko poškodovanostjo v časovni, ter frekvenčni domeni, z namenom izboljšanja oz. korekcije ocen vibracijskih poškodovanosti v frekvenčni domeni, glede na časovno domeno. Izpeljava matematičnih modelov vibracijskih poškodovanosti je podprta eksperimentalno. Primerjava ocen vibracijskih poškodovanosti je potrjena preko eksperimenta.

Title:Vibrational fatigue at impulse excitation
Abstract:
The presence of impulse loads causes errors in the estimation of vibrational damage in the frequency domain. The essence of the master thesis is to compare the estimates or deviations between vibrational damage in time and frequency domain, purpose of which is the improvement or correction of vibrational damage estimates in frequency domain, with reference to the time domain. The mathematical models of vibrational damage are supported experimentally. The comparison of vibrational damage estimates is confirmed through the experiment.

Keywords:linear systems, impulse excitation, material fatigue, spectral moments, vibrational damage
