Abstract
Tema ovog diplomskog rada je analiza čvrstoće kućišta brzozatvarajućeg ventila parne turbine. Cilj zadatka je provjeriti čvrstoću kućišta numeričkom analizom i ispitati puzanje materijala u uvjetima eksploatacije. Prije analize čvrstoće kućišta potrebno je ispitati verifikaciju konačnih elemenata koji se koriste tijekom numeričke analize. Rješenja dobivena numeričkom analizom konačnim elementima uspoređuju se s analitičkim rješenjima s ciljem ispitivanja konvergencija rješenja. Čvrstoća kućišta brzozatvarajućeg ventila ispituje se u radnim uvjetima pri visokim temperaturama i radnom tlaku svježe pare. Cilj analize je dobiti naprezanja uz pomoć metode konačnih elemenata i na temelju toga odrediti faktor sigurnosti. Na kraju se određuje životni vijek kućišta brzozatvarajućeg ventila na puzanje materijala. Potrebno je ustanoviti broj radnih sati do inicijacije pukotine čija propagacija može dovesti do povećanja pukotine do kritične veličine, a i time do loma konstrukcije.
Abstract (english)
The topic of this thesis is the strength analysis of the housing of a quick-closing valve of a steam turbine. The aim of this task was to verify the strength of the housing by numerically analyzing and testing the creep of the materials in operating conditions. Prior to the analysis it's necessary to firmly examine the verification of the finite elements used during the numerical analysis. Solutions obtained by using finite elements during the numerical analysis are compared to the analytical solutions with the aim of examining the convergence results. The strength of the quick-closing valve housing is tested under operating conditions at high temperatures and fresh steam operating pressure. The aim of the analysis is to obtain the stress by using the finite element method and to define the factor of safety. In the end the service life of the quick-closing valve housing during creep is determined. It’s necessary to establish the number of working hours until the initiation of the initial crack whose propagation can lead to critical size, and thus to the fracture of the structure.
