Original Abstract

V článku je popsáno využití metody vstřikování výkonu pro experimentální určováni faktorů ztrát vazeb a faktorů tlumení. Dále je popsáno statistická nalýza této metody.

English abstract

In this paper is described Power Injection Method as suitable method for experimental identification of coupling loss factor CLF and lost factor LF. Statistical analysis of this method is also presented. Based on computer experiment we can state, that omission of in plane extension and shear modes produce error for measured CLF and LF within 10%. Next results are, that there is no significant differences between two types of averaging mentioned in literature. And that three measurement points for excitation and five measurement points for response are enough to state, that for presented structure standard deviation is no substantial in relation to mean value of predicted CLF and LF, if we consider that measured vibration energies has standard deviation 0,01*nominal value.
