Uticaj spojnice na dinamičko ponašanje elektromotora/The Influence of the Coupling on the Dynamic Behavior of Electromotor

Abstract

Dijagnostika ponašanja konstrukcije elektromotora je zasnovana na dinamičkom proračunu koji je realizovan primenom metode konačnih elemenata. Sopstvene frekvence i odgovarajući glavni oblici oscilovanja su određeni sa variranjem mase spojnice (do 600 kg). Proračunski model je obuhvatio sve podstrukture elektromotora. Modeliranje je izvršeno primenom konačnih elemenata grede, ploče (ljuske) i zapremine.

Diagnostic of the behavior of the construction of electromotor is defined based on the dynamic calculation realized by finite element method. Frequences and appropriate deformation fields were obtained on the variation of the clamp mass (to 600 kg). Model for calculation was involved all structures of the considered construction. Modeling was done by using beam, plate (shell) and volume finite elements.
