Magistrsko delo obravnava dinamsko analizo vpete vodne črpalke. Z uporabo modalne analize so bili analizirani uporabljeni materiali. Ocenjeno je bilo njihovo dušenje ter anizotropične lastnosti elastičnega modula. Izvedena sta bili eksperimentalna in numerična modalna analiza sestava črpalke. Dokazano je bilo ujemanje izmerjene in izračunane lastne oblike in razloženo odstopanje izmerjene lastne frekvence. Z razvitim numeričnim modalnim modelom je bilo raziskano ali črpalka zdrži predpisano naključno obremenitev.

• Title: Numerical and experimental modal analysis of a clamped water pump

Abstract

Master thesis focuses on the dynamic analysis of a clamped water pump. The materials used in the pump were analyzed using modal analysis. Their damping and anisotropic properties of elastic modulus were evaluated. Experimental and numerical modal analysis of the pump assembly was performed. Matching of experimental and numerical modal shape was proven and the deviation of measured natural frequency was explained. Using the developed numerical modal model it was researched if the pump assembly can withstand the prescriped random load.
