| Abstract: | Project WHEELS is a study to evaluate .the performance of individual standard military trucks both off and on road in relation to their missions and to cash savings possible through the elimination of special military automotive features, such as front -wheel drive, or the use of commercial vehicles in some missions . Such evaluations can only be based upon the most reliable assessments of mobility performance poss ib le . The AMC -71 Gr ound Mob ility Model was used to assess the off- and on-road speed performance of a group of military and commercial vehicles and vehicles with trailers or howitzers, totaling 48 cases of direct interest· and 6 reference vehi cles, ranging from 1 - ton gross vehicle weight to 90- ton gross combined weight . The terrain data used in predicting off-road perfor mance were obtained from transects, or strips of ground , about 3 by 52 km l ocated in West Ger many , Thail and, and Arizona, each representative of different types of climatic zones and terrain conditions . The road data used in predicting on-road performance were collected from segments of primary, secondary , and trail-type roads; each segment was appr oximately 100 miles long . Both off- and on- road performance was predicted in terms of speed for all vehicles and vehicle-trailer or - howitzer comb inations included in the study. Off- road speed was predicted for traverses made up of f ive straight lines equally spaced a long the length of the transects. On- road speed was predicted for the t9tal length sampled in each road category . Several off-road terrain traverse speed predictions were made . These included speed made over a combination of areal (patches of homogeneous terrain ) and linear (streams and rivers ) terrains identified as v110, speed over areal terrain· (V100 ), and speed over areal terrain with the worst 10 per cent removed from consideration (v90 ). On-road speed predictions were made for trails (v3 ), secondary roads (v2 ), and primary roads (v1 ). Performance in terms of percentage of off- and on-road areal terrains in the traverses and trails, respectively, that the vehicles could not traverse i s also indicated . Rruikings of the performance of the vehicles considered were made on the basis of the v90 and v3 speeds for each transect or r oad network. |
