Abstract
U radu je obrađena tema „Analiza posipanja česticama soli ovisno o geometriji i brzini vrtnje posipnog diska te veličini čestica metodom diskretnih elemenata“. Tema se nadovezuje na temu završnog rada „Traktorski priključak za posipanje soli“, a u ovom radu se razrađuje i analizira sustav za distribuciju soli na podlogu. Ravnomjerno posipanje propisane mase posipnog materijala po jedinici površine (g/m2) nosi mnogobrojne prednosti, što ekonomske, što u vidu osiguravanja sigurnog i nesmetanog prometovanja. Cilj ovog rada bio je pronaći kombinaciju parametara (vrsta i broj lopatica, brzina vrtnje posipnog diska i položaj otvora štitnika) koja zadovoljava rigorozne kriterije propisane normama i pravilnicima u području zimskog održavanja prometnica. U sklopu rada prvo je proveden uvid u zakonsku regulativu te opisan postupak klasifikacije i certifikacije posipača. Nakon toga slijedi poglavlje u kojem je objašnjena metoda diskretnih elemenata zajedno sa softverskim paketom EDEM koji je korišten za rješavanje i analizu zadanog problema. Slijedi opis ulaznih podataka simulacije te analiza dobivenih rezultata. Rezultat analize je odabrana kombinacija ranije spomenutih parametara koja je konstrukcijski razrađena i oblikovana u 3D model s odgovarajućom tehničkom dokumentacijom u 3D CAD (Solidworks) softveru.
Abstract (english)
Title of the master’s thesis is „DEM analysis of a salt particles distribution depending on a geometry and rotation speed of a spreading disc and particles sizes“. Master’s thesis continues on a bachelor’s thesis „Agricultural vehicle extension for salt spreading“. In master’s thesis focus is on a development and analysis of salt spreading assembly and spreading pattern. Using a uniform spreading pattern has many benefits, economical as well as ensuring safe and undisturbed traffic. Purpose of this thesis was to find which combination of parameters (type and numbers of blades, rotational speed of a spreading disc and position of an opening) fulfils rigorous performance requirements for winter road maintenance. In the first part of the work norms and regulations are given, then follows a chapter about classification and certification of salt spreaders. Next chapter is about DEM (discrete element method) combined with introduction to EDEM software which was used to solve and analyze given problem. After that follows a detailed description of the input data and finally analysis of output data. Result of the analysis is chosen combination of earlier mentioned parameters with corresponding 3D model and technical documentation created in 3D CAD (Solidworks) software.
