Dummy Design and Reaction at Impact Simulation

The influence of neck flexibility of the Hybrid-II-dummy on the Head Injury Criterion is investigated by means of sled tests. HIC-values were found to increase significantly with decreasing neck stiffness.

Furthermore, characteristic properties of this dummy type with regard to reproducibility and durability are discussed; kinematic properties of spine and rib cage are compared with the human eqivalents.

Finally, adjustability of this dummy type and various test methods, especially neck tests, are closely examined.

Proposals for certain improvements are made.
