Abstract

Ovaj rad bavi se procesom konstruiranja miješalice za beton sa automatiziranim punjenjem. Na početku rada prikazuju se neki od načina uporabe i pripreme betona. Ukazuje se na neke prednosti koje sa sobom donosi priprema betona uz pomoć automatizirane miješalice. Zatim se provodi analiza tržišta koja daje uvid u trenutno stanje tehnike na području pripreme betona. Znanje stečeno analizom tržišta koristi se pri izradi funkcijske dekompozicije i morfološke matrice miješalice. Uporabom morfološke matrice generira se nekoliko koncepata, koji se zatim međusobno uspoređuju i ocjenjuju. Najbolje ocijenjeni koncept se detaljnije razrađuje. Detaljna konstrukcijska razrada koncepta uključuje proračunavanje svih potrebnih dijelova miješalice, te generiranje 3D modela sa pripadajućom tehničkom dokumentacijom. 3D model miješalice izrađuje se u programskom paketu Solidworks, dok se proračun čvrstoće provodi uz pomoć analitičkih formula iz navedene literature.

Abstract (english)

This thesis handles the process of designing a concrete mixer with automated loading. The paper begins by exploring different methods of utilizing and preparing concrete, highlighting the advantages of using an automated mixer. A market analysis is conducted to gain insight into the current state of the art in the field of concrete preparation. Based on this analysis, the functional decomposition and morphological matrix of the mixer are developed. Using the morphological matrix, various concepts are generated, compared, and evaluated. The highest-rated concept is then further developed in more detail. This includes the calculation of the strength of all necessary parts of the mixer and the creation of a 3D model with associated technical documentation. The 3D model is generated using the Solidworks software package, while the strength calculations are performed with the help of analytical formulas sourced from the cited literature.
