摘要：	Existing rigid body dynamics and finite element computer codes do not have adequate databases for manikin neck structures to properly model head/neck system dynamics occurring in crash or ejection testing. This report describes measured static stiffness and dynamic damping and stiffness characteristics of the Hybrid II and Hybrid III manikin necks and uses these data to improve the current manikin neck data sets of the Articulated Total Body (ATB) model and the Head Spine Model (HSM). The Hybrid II and Hybrid IIT manikin necks are used extensively throughout the automotive industry, the Department of Transportation, and the Department of Defense for safety testing. Static stiffness characteristics were determined from loading and unloading the necks in flexion, extension, and lateral bending. Dynamic damping and stiffness characteristics were determined from abrupt deceleration tests in the 'X' and 'Y' directions. Current computer data sets for the Hybrid II and Hybrid III necks were compared to the experimental dynamic results to determine inconsistencies. The data sets were, then revised using the results obtained experimentally. Finally, the new data sets were compared to the experimental dynamic results to show improvements.
