Abstract

Zbog sve veće potrebe za razvojem društva i trgovine te povezivanja svijeta sve je veći i brži razvoj teretnih vozila koja osiguravaju prijevoz različitih vrsta dobara. Zbog toga se razvijaju i mnoge vrste nadogradnji za teretna vozila specifična za pojedine grane industrije.
U ovom radu prikazan je razvoj nadogradnje za rasute terete. Na početku rada prikazana je kategorizacija vozila za prijevoz tereta te zakonske odredbe i propisi u vezi s dimenzijama i masom vozila te osovinskim opterećenjima. Nadalje su prikazani zahtjevi i upute proizvođača odabranog teretnog vozila na koji se postavlja nadogradnja. Prema tome je izrađena lista kriterija koje nadogradnja treba ispuniti i s time se išlo u konceptualnu fazu gdje su bila predstavljena tri koncepta koja su vrednovana prema odabranim kriterijima. Razradbena faza započela je odabirom vozila i šasijom, a nastavila se oblikovanjem podkonstrukcije i sanduka (okvir i stranice) te veza šasije i podkonstrukcije. Izvršen je proračun čvrstoće podkonstrukcije, osovinskog opterećenja, opterećenja hidrauličkog cilindra u tri kritična slučaja (početak podizanja sanduka, bočno kipanje i stražnje kipanje) te proračun oslonaca sanduka. Nakon toga se odabrao hidraulički cilindar za podizanje sanduka i izvršio izračun konačne nosivosti.
Na kraju je izrađen 3D model nadogradnje za rasute terete i pripadajuća dokumentacija.

Abstract (english)

Due to the growing need for the development of society and trade and the connection of the world, there is a fast-growing development of commercial vehicles which ensure transport of various types of goods. That is why many types of superstructures for commercial vehicles specific to certain industries are being developed.
This paper presents the development of a truck superstructure for transporting bulk cargo. At the beginning of the paper, the categorization of vehicles used for transporting goods is presented. Also, the laws and regulations considering dimensions, mass and wheelbase of commercial vehicles are presented. Furthermore, the requirements and instructions from the manufacturer of the selected truck on which the superstructure is installed are presented. Therefore, a list of criteria that the superstructure needs to meet was made. The criteria were then used for the conceptual phase of three concepts which were evaluated according to the chosen criteria. The development phase starts with the choice of a vehicle and the chassis, and it is continued with the design of the subframe and the truck bed (frame and sideboards) and the design of the joints between the chassis and the subframe. Stress analysis of the subframe and the truck bed supports is presented. Calculation of the axle loads is also presented. The calculation of the hydraulic cylinder is presented for three critical cases (start of the bed tipping, sideways tipping and rear tipping). Afterwards, hydraulic cylinder used for bed tipping was selected and the final truck maximal load was calculated.
Finally, a 3D model of the superstructure for transporting bulk cargo was made with the following technical documentation.
