Modalna analiza minijaturnih struktura
Modal analysis of miniature structures
Апстракт
Jedan od standardom propisanih postupaka u remontu turbogeneratorskih postrojenja je i modalna analiza lopatica. Problem se javlja kada su u pitanju minijaturne lopatice uvodnih stepeni, gde standardna oprema ne može da se primeni zbog dimenzione inkompatibilnosti. U tom slučaju postoje dva moguća rešenja: jedno je nabavka nove, skupocene i namenske aparature, a drugo izrada odgovarajućih adaptera i prilagođenja za standardnu opremu. Prilikom modalne inspekcije rotora parne turbine (P = 60 MW) na lokaciji TE Kolubara - A korišćeni su klasični instrumenti za spektralnu analizu oplemenjeni odgovarajućim originalno izvedenim adapterom za merenje na minijaturnim lopaticama. Opis samog adaptera i postupka analize detaljnije su izloženi u radu.
One of the standard prescribed overhaul procedures for turbo-generator plants is the modal analysis of blades. A problem occurs with the miniature blades of introductory levels, where standard equipment cannot be used due to dimensional incompatibility. In that case there are two possible solutions. One is to purchase new, expensive and specific purpose apparatus, and another is to make adapters and adjustments to the standard equipment. During the modal inspection of the steam turbine's rotor (P = 60 MW) on the location of the thermal power plant Kolubara - A, the conventional instruments for spectral analysis were used, but with an originally made adapter for measuring on the miniature blades. The description of the adapter and analysis procedure are given in detail.
