Abstract:V okviru magistrske naloge so na obstoječi elektromagnetni zavori določeni podatki navitja in izmerjena celotna geometrija kotve ter jarma. Omenjeni podatki so vključeni v numerični model elektromagnetne zavore. Cilj numeričnega izračuna z metodo končnih elementov v programskem paketu Ansys je določitev karakteristik magnetnih sklepov ter elektromagnetnih sil v odvisnosti od velikosti električnega toka ter zračne reže. Pridobljene karakteristike predstavljajo magnetno nelinearne parametre dinamičnega modela elektromagnetne zavore. Dinamični model elektromagnetne zavore je zapisan s sistemom enačb električnega in mehanskega podsistema elektromagnetne zavore v programskem paketu Matlab/Simulink. Na osnovi rezultatov simulacij je mogoče določiti vklopne čase in izklopne čase elektromagnetne zavore. Zaradi vse večjih zahtevanih stopenj zanesljivosti ter varnosti pri delovanju elektromagnetnih zavor predvidevamo, da bodo pridobljeni rezultati simulacij uporabni pri nadaljni analizi ter izdelavi elektromagnetnih zavor, torej tudi v gospodarstvu pri proizvajalcih.
Keywords:Ansys Workbench, dinamični model, elektromagnetna zavora, metoda končnih elementov, numerična analiza, magnetno polje, magnetni sklep.

Title:NUMERICAL CALCULATION OF PARAMETERS FOR THE ELECTROMAGNETIC BRAKE DYNAMIC MODEL
Abstract:In the context of the master thesis the winding data on the existing electromagnetic brake are determined and all the geometry of the armature and the yoke is measured. This data are included in the numerical model of the electromagnetic brake. The aim of the numerical calculation in Ansys sofware by finite element method is to determine the flux linkage and the electromagnetic force characteristics as a function of the electrical current and air gap size. Obtained characteristics represent the magnetic parameters of the nonlinear dynamic model of the electromagnetic brake. The electromagnetic brake dynamic model is written with a system of equations of the electrical and mechanical subsystems of the electromagnetic brake in the Matlab/Simulink software. Based on the simulation results it is possible to determine the engaging and releasing times of the electromagnetic brake. Due to increasing requirements of reliability and safety in the operation of electromagetic brakes it can be assumed, that the obtained simulation results will be useful further analysis and manufacturing of electromagnetic brakes.
Keywords:Ansys Workbench, Electromagnetic brake, finite element method, numerical analysis, magnetic field, flux linkage.
