Simulations of mechanical loads on elements of a spring mechanism

V tem diplomskem delu bomo predstavili MKE-simulacije mehanskih obremenitev elementov vzmetnega mehanizma s programom Solidworks. MKE-simulacija je metoda za analizo lastnosti neke geometrije in odziva te na neko obremenitev. Te simulacije bomo kreirali za tri elemente vzmetnega mehanizma, ki je v našem primeru tečaj zamrzovalne skrinje. Ti elementi so izpostavljeni različnim vrstam obremenitev in imajo različne zahteve. S pomočjo simulacij po MKE-metodi bomo presodili, ali so elementi primerno dimenzionirani na podlagi primerjalne napetosti po von Misesu. Najpodrobneje bomo predstavili nastavitvi mreže in robnih pogojev, saj najbolj izrazito vplivata na pravilnost rezultatov. Prav tako bomo predstavili simulacije elementov vzmetnega mehanizma s statičnimi in nelinearnimi analizami in njihove nastavitve. Predstavili bomo rezultate teh simulacij, ki potrjujejo primernost dimenzioniranja elementov vzmetnega mehanizma. Ugotovili bomo, da lahko Solidworksov simulacijski paket uporabimo za veliko število primerov, vendar ne moremo simulirati nekaterih zahtevnejših pojavov).This thesis will present FEA simulations of mechanical loads on the elements of a spring mechanism using Solidworks. FEA simulations are a method for analyzing the properties of a geometric shape and the response of this geometric shape to a load. These simulations will be created for three elements of the spring mechanism, which is a spring-loaded hinge of a freezer. These elements are exposed to different kinds of loads and have different requirements. Using FEA simulations, it will be determined if the elements are properly dimensioned according to the von Mises stress criterion. The thesis will focus on the parameters used for meshing and creating fixtures, as these two parameters have the greatest effect on the final results. It will also present the simulations of the spring mechanism elements with static and non-linear analyses, and their parameters. It will present the results of these simulations which confirm that the elements are properly dimensioned. It will be established that the simulation package included in Solidworks can be used in many cases, however there are some complex effects which cannot be simulated
