Abstract
The spectral density analysis of the articulated vehicles is a subject of great
importance and it is widely applied in the area of vehicles design and safety.
So the vehicles when ride over rough roads, respond dynamically and
inadequate road holding may arise .This paper examines the ride safety of an
articulated vehicle over irregular roads through an analytical study .The
vehicle responses to road surface undulations are studied using spectral
density approach which is reviewed and then applied on a vehicle model to
obtain the dynamic wheel loads a the results are drawn from the classical
system and conclusions are drawn as to the applicability of this approach. For
loaded and unloaded articulated vehicles, it may be concluded that for
unloaded vehicle the danger of the departure of the wheel from the road is
higher than with the loaded vehicles.
