THE INFLUENCE OF THE POSITION OF LONGITUDINAL STIFFENERS TO THE OPTIMUM DIMENSIONS OF THE BOX SECTION OF THE SINGLE-GIRDER BRIDGE CRANE

Abstract

U radu je razmatran problem optimizacije sandučastog poprečnog preseka glavnog nosača jednogredne mosne dizalice. Težište rada je istraživanje uticaja koji ima položaj podužnih ukrućenja na vertikalnim limovima na optimalne dimenzije sandučastog poprečnog preseka glavnog nosača, kao i na ukupnu masu nosača. Za položaj podužnih ukrućenja uzete su različite vrednosti koje se najčešće preporučuju. Smanjenje mase nosača postavljeno je kao funkcija cilja. Kao metoda za određivanje optimalnih geometrijskih parametara kutijastog preseka korišćen je GRG2 algoritam optimizacije. Kao funkcije ograničenja uzeti su kriterijumi čvrstoće, lokalne stabilnosti limova, krutosti, dinamičke krutosti, minimalna debljina limova, kao i ograničenja tehnologičnosti. Prikazani su rezultati za karakteristične položaje podužnih ukrućenja za jednu izvedenu jednogrednu mosnu dizalicu

Keywords

jednogredna mosna dizalica, sandučasti poprečni presek, podužna ukrućenja, optimizacija, eurokodovi
