Model Overview

The HRS CAD accommodation model is a parametric model intended to provide 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 yoke and pedal locations. Clearances between the user and surrounding interior vehicle surfaces have been added per MIL-STD-1472 (e.g. head clearance required from head (helmet) to vehicle roof line). Direct vision zones, including to screens at eye level, have been added based on MIL-STD-1472 and SAE Recommended Practice J1050.

Intended Use

The HRS: Driver CAD accommodation model is applicable to certain vehicles that have a reduced vehicle profile, requiring the crew to sit in a more reclined position, and where the crew performs most of the tasks fully under-armor.
