It was created a simple model of one-side fixed beam with the dovetail groove and the damping strap in it. There was contact included between sidewalls of the strap and the groove. Main aim was to determine how the strap s hape influencing the natural frequency and the damping coefficient. It was observed a time-dependency of the displacement. This signal was converted to the frequencydomain by FFT algorithm. In this Fourier’s spectrum was easy to determin e the response frequencies. The damping coefficient was determined pursuant to the resonance curve bandwidth in certain distance. It was performed several simulations with various parameters, and results were plotted to graphs. 000003776 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000003776 653__ $$a 000003776 7112_ $$aEngineering Mechanics 2008$$cSvratka (CZ)$$d2008-05-12 / 2008-05-15$$gEM2008 000003776 720__ $$aLošák, P.$$iMalenovský, E. 000003776 8560_ $$ffischerc@itam.cas.cz 000003776 8564_ $$s578498$$uhttp://invenio.itam.cas.cz/record/3776/files/Losak_FT.pdf$$y Original version of the author's contribution as presented on CD, , page 530. 000003776 962__ $$r3717 000003776 980__ $$aPAPER
