Eksperimentalna in numerična analiza različnih rotorjev pri EC puhalu na upogibna nihanja

Kavčič, Rok (author), Boltežar, Miha (mentor)

V tem delu je predstavljena eksperimentalna in numerična analiza različnih rotorjev pri EC puhalu na upogibna nihanja. Vsi strojni deli imajo vsaj eno lastno frekvenco nihanja in pri obratovanju naprave se moramo te frekvence čim bolj izogibati. Nihanje strojnih delov povzroči obrabo strojnih delov in posledično manjšo življenjsko dobo izdelka. Za ugotovitev lastnih frekvenc rotorjev smo uporabili eksperimentalni in numerični način analiziranja.

• Title: Experimental and numerical analysis of different rotors in the EC blower on bending oscillations

Abstract

The work presents experimental and numerical analysis of different rotors in the EC blower on bending oscillations. All machine parts have at least one own frequency of oscillation and we have to avoid these frequencies in operating devices as much as possible. The oscillation of the machine parts results in the wear of the machine parts and, consequently, the lower life of the product. The experimental and numerical method of analysis was used to determine own frequencies of the rotors.
