Optimizacija postupaka tehničke dijagnostike hidroelektrana / Optimization of technical dijagnostics of hydroelectric

Nikolić Dragan 08 May 2008 (has links)
<p>Doktorska disertacija ima za cilj da&nbsp; teoretski i empirijski, kontrolicano, sistematski i kritički ispita hipotezu formiranja modela optimizacije postupaka tehničke dijagnostike, pri izboru najznačajnijih parametara u određivanju sigurnosti funkcionisanja sastavnih komponenti sklopova hidroelektrane. Određenim vrednostima analizirane pouzdanosti određen je univerzalni model optimizacije na osnovu model blok dijagrama i mernih mesta. NJihovim međusobnim uticajem i povezanošću formira se: korelacija parametara optimizacije mehaničkih oscilacija i temperature, korelacija parametara optimizacije mehaničkih oscilacija i pohabanosti ležajeva i korelacija parametara optimizacije radnih temperatura i pohabanosti leđajeva. Ovakav model je univerzalnog tipa jer se može primeniti i na složene sisteme, bez obzira na dimenzije komponenti sklopova.</p> / <p>The doctorssca dissertacion problems connected to gear choice which have<br />been exited by now have been solved in the paper. This model we can determining optimal model<br />tehnical diagnostic hydro electric plants. It has been done by its general quality estimation well as<br />problem of quality control. That was solved here on the example of gears. One of the aims of the<br />paper is development of personal approach to quality evoluation and compound mechanical<br />systems reliability, gear in this case. The evoluation process of design solution has been done by<br />computing the value for every gear being analysed and based on that it has been established<br />which gear is better.</p>
