Evaluation of WES Analytical Model in Selected Terrains (XM559E1 GOER Tests at Camp Gagetown, New Brunswick, Canada)

Abstract

This study was conducted to (a) evaluate the performance of the 8-ton XM559E1 GOER when operating in selected Canadian terrains and (b) evaluate the capability of the WES analytical model to predict the performance of an 8-ton XM559E1 in selected Canadian terrains. Speed and motion resistance tests on secondary roads, cross-country speed tests, drawbar pull-slip tests, and towed off-road motion resistance tests were conducted. Where pertinent, soil, surface, geometry, and vegetation data were collected before or after each test, and speed, vertical and longitudinal accelerations, percent wheel slip, and drawbar pull were measured. A comparison was made of actual performance and performance as predicted by the analytical model. The average of the absolute deviation of actual from predicted speeds for the tests conducted was 1.36 mph.
