VIBRATION ANALYSIS OF THE CAR BODY STRUCTURE UNDER THE EFFECTS OF ITS ENGINE

Abstract

The paper presents finite element models to study specific vibration and
stimulated vibration characteristics of car body shell structure. Specific vibration
characteristics are calculated and simulated on finite element software. Based on
the analysis of specific vibration, the paper conducts calculations and simulations
of vibration of the body structure under the stimulation of the engine placed on
the vehicle. Through these results, it is possible to preliminarily assess the
structural features of the car body, as well as the effect of the structure on the
noise level inside the vehicle.
