Modelling of Vibration of Mobile Vehicle

Abstract

The movement of vehicle on uneven roads causes vibration of its
sprung and unsprung parts. Vibrations of the sprung part of the car
cause fatigue for drivers, creating uncomfortable and sometimes
unsafe conditions for them. A systematic analysis of the vibration
process occurring in a mobile vehicle can be helpful in evaluating the
properties of the vehicle to protect the driver, passengers, transported
goods and structural elements of the car from dynamic loads resulting
from the interaction of wheels with road irregularities. This paper
presents the mathematical model of vibration of mobile vehicle and
the results of the computer simulation of vibrations of a mobile vehicle
on different road surfaces in the MATLAB +Simulink software
environment.
