Copyright © 1998 Society of Automotive Engineers, Inc. ABSTRACT A 3-dimensional, full-vehicle computer model was cre- ated of a conventional 218 tonne payload capacity mine haul truck. Simulations were performed of a number ofsituations typifying in-service operation to gain insightinto various aspects of the dynamic response of thehauler. A 0.25 g lane change maneuver was simulatedthat can represent a wide range of haul truck movementsin a mine, such as collision avoidance or following achange in haul road alignment. Peak wheel loads ofapproximately 100 tonne were recorded, and these areabout 1.7 times greater than the rated capacity of the tire.Travel on an uneven haul road was also simulated anddynamic wheel loads were predicted that are 1.3 timestire static loads. The characteristics of the road surfaceused in the simulations were measured with an ARRBTransport Research Ltd. road profiler. Unevenness fea-tures of sealed and unsealed roads are presented anddiscussed. The methods described in this paper can beused to quantify haul truck dynamic loads and the effectof haul road unevenness on tire and component life. INTRODUCTION Off-highway mine haul truck design engineers are facedwith a wide range of challenges, both in developing adeeper understanding of existing designs to solve day-to-day problem
