An Improved Dummy Neck for the ISO 13232 Motorcycle Anthropometric Test Dummy
Published May 19, 2003 by National Highway Traffic Safety Administration in United States
A new test dummy neck with improved biofidelity was developed specifically for motorcycle crash testing and is specified in the first revision of ISO 13232. This new neck has been approved to replace the modified Hybrid III neck originally specified for the Motorcyclist Anthropometric Test Device (MATD). The new neck was designed, with the aid of mathematical modelling, to address the unique posture and multi-directional biofidelity requirements of the MATD. It incorporates materials and features that are new to dummy neck design. It can be adjusted for a wide range of inclined torso angles that are associated with the large variety of motorcyclist riding postures. Biomechanical performance data for the new neck are presented that demonstrate characteristics in good agreement with various volunteer and cadaver test data. Additionally, an extensive series of high-energy tests have been conducted to evaluate the new design's reliability and repeatability.
