Abstract

Military ground vehicles are currently designed using requirements from MIL-STD-1472, 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. The fourth in a series of accommodation models being created is the Fixed Human Accommodation Reference Point (HARP): Commander accommodation model. Verification is intended to build confidence in the Fixed HARP: Commander CAD accommodation model for use in ground vehicle design.  This model is applicable to ground vehicle commander workstations where the users interact with a keyboard, screen, and have an adjustable seat back.  The model provides the composite boundaries representing the body of the defined user population, including the effects of posture, and protective equipment and gear.  The boundaries defined include the required space needed for the equipped users’ helmet, torso, elbows, knees, eye location, and boots.  The model also generates preferred and acceptable ranges of keyboard locations.
