Determinations regarding the influence on movement and comfort of different elastic suspension structures in N2 type vehicles

Abstract

Modern technologies implemented in the automotive field bring a considerable increase of performance, but also safety at the same time. Moving the vehicle under such conditions also requires a high level of comfort, regardless of the type of road traveled.The dynamics and behavior of the vehicle are conditioned by its constructive and functional characteristics. The research carried out highlights some aspects regarding the importance of elastomeric elements in the structures destined for shock and vibration damping.Thus, different solutions adopted are analyzed, for the car's damping system, to reduce the specific disturbance factors of the road. For a vehicle of average load capacity, respectively 5 tonnes, used in determinations, checks are made on the various elastic systems with role in reducing shocks and vibrations. It is also intended that for the solutions adopted, the frequencies and amplitudes of the vibrations will occur at low values. By modeling the systems in AMESim, the aim is to identify the performance of the solutions adopted, as well as the level of comfort obtained.
