An Automated Tool for Predictive Neck Load Simulation During Individual Warfighting Maneuvers

As the focus on survivability, injury prevention, armor design, and human centric design increases, more attention must be paid to human modeling, especially with regards to the head and neck, not only for protection against ballistics and impact, but also for biomechanical issues as a result of normal operating conditions. There is a distinct need for an accurate, easy-to-use, modeling and simulation tool that helps design appropriate head gear, including helmet attachments such as night vision equipment and other sensors. Through a balance of advanced research and customer-driven product development, Viz-Tek and the University of Iowa have developed the fundamental capabilities necessary for building a state-of-the-art head-and-neck simulation tool. This tool will provide an intuitive simulation environment, capable of evaluating biomechanical forces on the neck vertebrae, and determining consequent stresses and displacements of the neck muscles. Such a tool can be used to help design equipment through the conduct of tradeoff analysis. When completed, it will provide product designers and analysts with an effective environment for evaluating new designs, modifying existing designs, and analyzing loads placed on the helmet, fit and comfort, protection coverage, and compatibility with other armor configurations in terms of collisions and interference.
