dc.description.abstractThis paper describes a design of the protective frame orchard tractors and tractor power up to 65kW for use in fruit production on sloping ground for mechanical harvesting (shaking) of stone fruits. Shown protective frame can be mounted on existing models of tractors, primarily domestic production. This paper presents an analysis of the stress state of the observed protective frame mode unwanted case overturning tractor. A common practice in the examination and approval of protective frames to be loaded twice the force of gravity of the tractor. Analysis of the protective frame was done using the software package SolidWorks gain and methods of FEM analysis. Ram is loaded with a horizontal and vertical force of 38,2 kN on the side and from above. The results obtained show a satisfactory security.en
dc.description.abstractU ovom radu prikazano je jedno konstruktivno rešenje sigurnosnog rama za voćarske traktore i traktore snage do 65 kW koji se koriste u voćarskoj proizvodnji na nagnutim terenima za mašinsko ubiranje (trešenje) koštičavog voća. Prikazani sigurnosni ram može se montirati na postojeće modele traktora, pre svega domaće proizvodnje. U radu je izvršena analiza naponskih stanja posmatranog sigurnosnog rama u režimu neželjenog slučaja prevrtanja traktora. Uobičajena praksa pri ispitivanju i homologaciji sigurnosnih ramova je da se opterete dvostruko većom silom od težine samog traktora. Analiza sigurnosnog rama vršena je pomoću softverskog paketa SolidWorks korišćenjem metode MKE analize. Ram je opterećen silom od 38,2 kN sa bočne strane i sa gornje strane. Dobijeni rezultati ispitivanja ukazuju na zadovoljavajuću bezbednost.sr
