Modelo tridimensional de análise dinâmica com implementação numérica de um veículo automotor

Abstract

In summary, the present study proposed a three-dimensional model followed by a numerical implementation that aimed to analyze the dynamic behavior of a motor vehicle with 6 (six) degrees of freedom. The model was elaborated from the perspective of the ride phenomenon, aiming at explaining the dynamic behavior of a motor vehicle under predetermined conditions. Two case studies were carried out, a passenger automotive model and an off-road automotive model, to allow the evaluation of geometric, structural and constructive properties. Therefore, each case study was evaluated for two distinct responses, a response relating to a constant excitation and another response concerning the application of a motion pulse added to this constant excitation. Under the progress and execution of the present work, it was possible to determine the main modes of vibration corresponding to the governing degrees of freedom employed, as well as to address points of interest within the technical specifications of the case study models, since a series of variables And their dynamic responses the weighted requests were analyzed.
