Vibration Simulation of Articulated Dump Truck with the
The paper is concerned with the vibration for the articulated dump truck (ADT) which is multi-axle vehicle and different from rigid dump truck. The balanced suspension was employed as the rear suspension in the 60t ADT which the paper takes as the research object. A vibration model of 6 dof for the truck was proposed. The impact of the variation of longitudinal center of gravity …

Liming · This paper reports on an investigation of articulated dump trucks vibration analysis and rear suspension stiffness sensitivity analysis. Since the frame of the off-highway dump truck is integrated, the impact from the road surface against the rear wheel is transmitted to the cab directly through the hydro pneumatic suspension and the frame, and finally contributes to the …

Ride Comfort Aspects of Heavy Truck Design
781067. The design of heavy trucks with respect to the ride comfort poses two classical problems. One is the articulated vehicle problem and the other is the "jumping ride" problem caused by elastic vibrations of the frame. The two problems have been identified in field investigations. The vibration isolating system of a truck has been
