Performance Requirements and Characteristics of Mechanical Necks
A short history of the development of mechanical necks for anthropomorphic dummies is given. The response envelopes recommended by Mertz and Patrick are reviewed. A modified performance requirement for mechanical necks based on this data, but emphasizing loading corridors, is set forth. Autogenous and dynamic neck trajectories for the volunteer LMP are presented, and the difficulties of establishing a trajectory performance requirement are discussed.
Commerical necks were tested and found to be incompatible with the performance requirements. Several experimental necks were tested and one, the GMR Polymeric Neck, demonstrated the feasibility of satisfying the requirements. However, additional efforts are required to assure proper performance of this neck when used in conjunction with a total dummy structure under a wider range of test conditions.
