Klanjšček, Jan (author), Slavič, Janko (mentor), Boltežar, Miha (comentor)

Problematika magistrske naloge je izboljšati merilno mesto pogona alternatorjev v gluhi sobi. V sklopu naloge smo opravili več sprememb na konstrukciji mize, ki so privedle do bolj masivne in toge strukture. Izvedli smo tudi nadgradnjo števila mikrofonov pri meritvah hrupa alternatorjev iz deset na dvajset. Izvedli smo meritve zvočne moči na starem in novem preizkuševališču ter primerjali rezultate. V zaključku smo opazovali, kako so določene spremembe na pogonski mizi vplivale na meritve hrupa.

• Title: Remodeling of alternator drive test bench in anechoic chamber

Abstract

The goal of the master thesis is to improve the measuring set-up of the alternator drive in the anechoic chamber. As part of the assignment, we made several changes to the measuring table that resulted in a more massive and rigid structure. We also increased the number of microphones for alternator noise measurements from ten to twenty. Finally, we performed sound power measurements at the old and new test sites and compared the results. In conclusion, we observed how certain changes to the drive table affected the noise measurements.
