Numeričko-eksperimentalna analiza čvrstoće strukturnih elemenata hidroelektrane

U ovoj disertaciji je prezentiran rad autora pod nazivom: "Numeričko - eksperimentalna analiza čvrstoće strukturnih elemenata hidroelektrane". Na bazi definisane metodologije dijagnostike ponašanja strukturnih elemanata hidroelektrane izvršeno je dijagnosticiranje ponašanja najvažnijih strukturnih elemenata hidroelektrane kao što su: cjevovod, račva i vratilo hidroagregata. Primjenom analitičkih i numeričkih metoda izvršena je analiza napona, dilatacija i pomjeranja cjevovoda kao cjeline. Definisana su kritična mjesta na cjevovodu sa aspekta i napona i deformacija pod različitim uslovima rada i opterećenja cjevovoda (unutrašnji pritisak, trenje, temperatura). Što se tiče napona to su mjesta na kojima se nalaze račve, a što se pomjeranja tiče to je kraj glavne cijevi cjevovoda...
This doctoral dissertation presents the work of the author entitled: "Numerical - experimental analysis of strength of structural elements in hydro - power plants". Diagnostics of the behavior of basic elements of the hydro - power plant such as: pipeline or penstock, bifurcation, and shafts is done on the basis of previously defined methodology of the diagnostics of the hydro - power plant structural elements behavior. Analysis of the stress, dilatations and deformations of pipeline as whole is done through the application of analytical and numerical methods. Critical places on the pipeline from stress and deformations point of view are defined under different exploitation conditions and regimes of work and also under different loads of pipeline (internal pressure, friction, temperature). As far as stresses are concerned those are the places where bifurcations are placed, and as far as deformations are concerned this is the place of the main pipe ends...
