Análise do comportamento dinâmico e vibratório de sistemas de suspensão passiva e ativa.

Abstract

One of the problems that more they are discussed in the automobile industry environment is the handling and comfort of vehicles in highways with adverse terrain. Both problems are related to the suspension systems and how they can react inside in certain situations within their operation limits. In this work the results of two mathematical models of suspension systems with seven degrees of freedom each, being one of the passive type and other a suspension system activates are compared. The systems are simulate in a digital process that creates an excitement sign that can be applied in the mathematical model in various ways. The results obtained him, always comparing the two suspension systems in same adversity conditions, show that the systems of the active type present a better reaction to the coming signs of the profile of the terrain.
