Diagnostic of the dynamic behavior of drive unit

Abstract

Dynamic behaviour of the drive unit was defined based on the dynamic calculation realized by finite element method. Frequencies and appropriate deformation fields (oscillations) were obtained by using program package KOMIPS. All structures of the considered construction of the drive unit were involved in calculation: gear-box (cover, input-shaft, middle-shaft and output-shaft), electromotor, coupling, performance shaft and momentum bar with the appropriate supports. Modelling was done by using plate (shell) and volume finite elements.
