Abstract

U završnom radu se razrađuje uređaj za dinamičko terensko balansiranje vratila. Predloženi uređaj koristi metodu oduzimanja amplituda (modificiranu metodu koeficijenata utjecaja) za određivanje iznosa i pozicije utega za balansiranje. Na temelju teorijske podloge metode, napisana je Matlab skripta pomoću koje se može izvesti simulacija radi testiranja metode u realnim uvjetima. Provedena je analiza rezultata dobivenih algoritmom za različite iznose amplitude šuma, i zaključeno je da je metoda održiva za traženu namjenu ako su izražene vibracije isključivo vezane uz disbalans vratila. Nakon ispitivanja razrađen je koncept uređaja i izabrane su potrebne komponente za izradu uređaja. Pomoću programa Altium Designer napravljene su sheme za potrebne sklopove na temelju kojih su izrađeni modeli tiskanih pločica spremnih za izradu uređaja.

Abstract (english)

In this bachelor's thesis, a concept for a device for dynamic field balancing of shafts is developed. The proposed device uses amplitude subtraction method (modified influence coefficient method) in order to calculate masses and positions of balancing weights. Based on the theorethical foundations, a Matlab script was developed in order to test the algorithm in realistic simulation created conditions. By analysing the results obtained by means of simulation for different amplitudes of white noise, it is concluded that the method is viable for this application, but only when there is a distinctive level of vibrations that is caused by shaft unbalance. After testing, the concept for the device was developed and needed electrical components were chosen. Using Altium Designer software, needed circuit schematics and printed circuit boards models were made in order to assemble the device.
