CREATION OF CAD ACCOMMODATION MODELS FOR MILITARY GROUND VEHICLE DESIGN

The objective of this effort is to create parametric Computer-Aided Design (CAD) accommodation models for crew and dismount workstations with specific tasks. The CAD accommodation models are statistical models that have been created utilizing data from the Seated Soldier Study and follow-on studies. The final products are parametric CAD models that provide geometric boundaries indicating the required space and adjustments needed for the equipped Soldiers’ helmet, eyes, torso, knees, boots, controls, and seat travel. Clearances between the Soldier and surrounding interior surfaces and direct field of view have been added per MIL-STD-1472H. The CAD models can be applied early in the vehicle design process to ensure accommodation requirements are met and help explore possible design tradeoffs when conflicts with other design parameters exist. The CAD models are available to government and industry partners and via the GVSC public website once they have undergone Verification.
