Military ground vehicles are currently designed using requirements from MIL-STD-1472G, the Department of Defense Design Criteria Standard Human Engineering. The MIL-STD, however, is difficult for designers to apply properly because it is often open to interpretation. Easy to use Computer-Aided Design (CAD) tools, such as accommodation models, are needed by the ground vehicle community, to address this issue (Zielinski, Huston II, Kozycki, Kouba, & Wodzinski, 2015). The first in a series of accommodation models being created is the fixed heel point (FHP) accommodation model. The V&V is intended to build confidence in the FHP accommodation model for use in ground vehicle design. The model is applicable to ground vehicles where driving is controlled via a conventional accelerator pedal and steering wheel configuration or in a vehicle workstation that requires the crew to interact with vehicle controls and displays using hands, horizontal directed vision, and adjustable seats (Zerehsaz, Ebert, & Reed, 2014). The FHP model is intended to provide the composite boundaries representing the body of the defined target Soldier population, including posture prediction. The boundaries defined provide required space claim for the encumbered Soldier’s helmet, eyes, torso, and knees. Clearances between the Soldier and surrounding interior vehicle surfaces have been added per MIL-STD- 1472G (e.g. head clearance required from head (helmet) to vehicle roof line and thigh clearance to the steering wheel).
