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.
