Abstract

Abstract:
A mathematical model for a full vehicle dynamic system of 10 degrees of freedom is derived using Lagrange’s equation. The model is used to simulate the vibration response of the vehicle according to a road having sinusoidal disturbance for vehicle speed up to 200 km/hr. All the vehicle natural frequencies are evaluated. The vibration level of the driver and passengers are computed at different vehicle speeds and compared with the recommended values according to ISO 2631 standards.
