A Gps-Based Mobility Power Model For Military Vehicle Applications, George William Bozdech
Masters Theses
In recent years, military vehicles have been equipped with hybrid, diesel-electric drives to improve fuel efficiency and stealth capabilities. These vehicles require an accurate estimate of the power duty cycles during distinct operating conditions. To meet this demand, a GPS-based mobility power and duty cycle analysis is one approach to predict the power requirements of on-road and off-road vehicles. The dynamic vehicle parameters needed to estimate the forces developed during locomotion are determined from the GPS tracking data, and these forces include the following: the motion resistance, gravitational, linear inertia, rotational inertia, and aerodynamic drag. The motion resistance force generated …

Terrain Impacts From Vehicle Operations Across Multiple Passes, James Robert Kane
Masters Theses
This study, conducted on August 12th and 13th, 2008 at Fort Riley, Kansas on a clay loam soil, evaluated the terrain impacts of four commonly used tracked and wheeled military vehicles: the M1A1 Abrams Main Battle Tank, M998 High Mobility Multipurpose Wheeled Vehicle, M985 Heavy Expanded Mobility Tactical Truck, and M113 Armored Personnel Carrier. Disturbed width and impact severity were assessed along 14 spirals subjected to a maximum of eight consecutive passes for a total of 696 impact points. Data indicate that multiple passes produce increased vegetative impacts, with multipass coefficients ranging from 0.98 to 4.44 (compared to the commonly …
