Spectral analysis for randomly excited articulated vehicles

Abstract EN

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.
