Abstract: The study shows how the mobility performance of a 16-ton wheeled, light armored vehicle (LAV) is affected by systematic variations in number of axles, in tire size and/or in installed horsepower. The object of the study is to define the upper bounds of mobility performance for 16-ton wheeled LAV's as defined by these parameters, assuming the use in all cases of the best practical state-of-the-art suspensions matched to the overall vehicle configuration. The hull configuration of the parameteric vehicles derives from a 6x6 concept design developed by TACOM under the 1980-81 ACVT program. Twelve variations are examined in which changes in weight and geometry associated with power train and running gear variations are accounted for. The study uses the ride dynamics module (VEHDYN) of the Army Mobility Model (AMM) for characterizing ride and shock characteristics of the study vehicles, AMM for making off-road and on-road performance predictions, the SWIMCRIT/WACROSS water-crossing model for analyzing linear feature crossings and the WES DASH model for computing acceleration performance. Measures of mobility performance for the twelve study vehicles are developed using digital mobility-terrain data representing first the central highlands of the Federal Republic of Germany and second northeast Jordan. These data bases, each covering about 500 km, are available from earlier WES studies. Measures of mobility performance in each area are developed for each configuration. These are speed profiles on primary roads, on secondary roads, on trails, and off-road; percent of area impassable (NOGO) and percent of NOGO trail distances; reasons for immobilizations; and average times and speeds for standing-start dashes in the battlefield terrain. Predicted performances in dry, wet-wet slippery, and snow or sand conditions of the parametric vehicles are compared among themselves, and also to predictions for M1 Abrams Tank, M2 Bradley Infantry Fighting Vehicle, and two ACVT concept designs. Appendices present detailed vehicle data needed by the several models, discuss the terrain data, and list the mobility performance data developed by the several models. A final appendix examines the confidence level of selected statistics deriving from AMM speed data.
