Abstract

V diplomskem delu je predstavljeno, kako so bila določena področja, kjer so prisotne lastne frekvence pri delovanju pralnega stroja. Določitev področij je potekala z merjenjem in analizo signalov vibracij pri različnem številu vrtljajev bobna pralnega stroja. Ta področja so zelo neugodna pri delovanju pralnega stroja, zato je pomembno, da vemo, pri katerih vrtljajih so prisotna in se jim poskusimo v čim krajšem času izogniti. Za izvedbo meritve je bilo potrebno izdelati virtualni inštrument v programskem okolju LabVIEW, s pomočjo katerega je mogoče zajemati podatke o meritvah. Rezultati meritev in analize signalov so predstavljene v časovni in frekvenčni domeni.

Secondary title:	Characterization of washing machine's vibrations
Secondary abstract:	In this diploma paper, we presented the determination of areas in the operation of a washing machine where own eigen-frequencies were present. Areas were determinated through measurements and analysis of vibrations at different drum speeds of the washing machine. These areas were very inconvenient for the operation of the washing machine; therefore it was important to determine drum speeds where they appeared. Effort was made to avoid the areas as quickly as possible. For the implementation of measurement, a virtual instrument in the LabVIEW software environment was created. With its help, information on measurements was covered. Measurement results and signal analyses were presented in time and frequency domain.
