CREATION OF THE DRIVER FIXED HEEL POINT (FHP) CAD ACCOMMODATION MODEL FOR MILITARY GROUND VEHICLE DESIGN

The objective of this effort is to create a parametric Computer-Aided Design (CAD) accommodation model for the Fixed Heel Point (FHP) driver and crew workstations with specific tasks. The FHP model is a statistical model that was created utilizing data from the Seated Soldier Study (Reed and Ebert, 2013). The final product is a stand-alone CAD model that provides geometric boundaries indicating the required space and adjustments needed for the equipped Soldiers’ helmet, eyes, torso, knees, and seat travel. Clearances between the Soldier and surrounding interior surfaces and direct field of view have been added per MIL-STD-1472G. This CAD model 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 model will be available once it has undergone Verification, Validation, and Accreditation (VV&A) and a user guide has been written.
