EVALUATION OF THE RUNNING SURFACE DEFORMATIONS INFLUENCE ON THE VIBRATION BEHAVIOUR OF OFF-ROAD VEHICLES

Ovidiu Ioan Vulcu, Mariana Arghir

Abstract


Abstract: Road profile and the technical condition of the suspension affect a large measure of
comfort, road safety and endurance. This paper contains the theoretical study results of the offroad
vehicle vibration when running on a bumpy section of road. For this purpose has been
developed mechanical model of tire-suspension -self supporting bodyshell system with five degrees
of freedom. The bodyshell was approximated by a flat plate, suspension and tires were modelled
by four mass-damper-spring system attached to the four corners of the plate; the tire mass
together with a mass suspension is concentrated at a single point. Vertical vibration displacement,
velocity and acceleration of the body were determined using Matlab.

Key words: vehicle vibration, vehicle mechanical modelling, road deformation.
