Design, 3D model and calculation of pelleting machine

Zadatak rada je konstruirati, modelirati i proračunati stroj za izradu peleta, koji će biti konkurentan na tržištu. Prvi dio rada govori o peletima kao izvoru obnovljive energije, procesu peletiranja, analizira ekonomičnost upotrebe peleta, daje pregled Europske norme za pelete, opisuje i razmatra postojeće strojeve za izradu peleta. Drugi dio rada bavi se konstrukcijom stroja. Na osnovi analize postojećih rješenja određuje se lista zahtjeva i želja, morfološka matrica, prostoručnim skicama definira se koncept stroja i opisuje funkcije i tehničke karakteristike pojedinih komponenata i podsklopova. Treći dio rada je izrada 3D modela stroja u programskom paketu Autodesk Inventor Professional 2013 sa slikama komponenata, podsklopova i sklopova. Četvrti dio je proračun koji obuhvaća proračun sila, momenata i naprezanja na komponentama bitnim za funkcionalan rad stroja.The task of this paper is design, model and calculation of pelleting machine, which will be competitive in the market. The first part of the paper discusses the pellets as a source of renewable energy, the pelleting process, analyzes the economic use of pellets, gives an overview of European standard for pellets, describes and analyzes the existing machines for the production of pellets. The second part deals with the design of the machine. List of demands and desires, morphological matrix, freeform drawings defined the concept of the machine and describes the functions and specifications of individual components and sub-assemblies are determined based on the analysis of existing solutions. The third part of the paper is the creation of a 3D model of the machine in the software package Autodesk Inventor Professional 2013 with images of components, sub-assemblies and assemblies. The fourth part is a calculation that includes a calculation of forces, moments and stresses on the components essential for the effective functioning of the machine
