Performance Specifications for a Midsize Male Pedestrian Research Dummy
While it is recognized that collisions involve pedestrians of all sizes, this Information Report addresses performance specifications for a 50th percentile adult male research dummy. This approach stems from the greater knowledge of biomechanics and existing dummy technologies for the mid-size male relative to other adult sizes and children. While not the initial objective, it is envisioned that additional performance specifications for other sizes of pedestrian research dummies will be developed in the future based on accepted scaling procedures. The specific requirements for the pedestrian dummy have been based on a collective assessment of pedestrian injury, response, and anthropometry priorities from the experimental, epidemiologic, and computational literature. In general, the objective was to specify performance specifications based on human characteristics and the impact response of post-mortem human subjects rather than to specify the design of a particular physical device. To facilitate and encourage the immediate use of such dummies, however, this information report was limited to specifications which could be met by existing technologies. Furthermore, it was recognized that it was necessary to have a physical representation of such a research dummy in order to assess the feasibility of meeting the dummy performance specifications using existing technologies. Thus, only existing configurations of dummy hardware were considered. Based on the perceived applications for a research pedestrian dummy, the primary focus of the information report centered on biofidelic whole-body kinematics during a vehicle-pedestrian impact. Specific body regions were prioritized based on a combination of pedestrian injury, including both severity and frequency, as well as the capabilities of existing dummy hardware. Based on the priorities established by a review committee, the specifications provided in this information report include both mandatory and recommended requirements as indicated by the terms "shall" and "should", respectively. As pedestrian injury trends and dummy hardware continue to evolve in the future, it is anticipated that this information report will expand to include more mandatory requirements in more body regions. Finally, it should be noted that the test procedures described in this document only apply to the specific tests required to verify dummy performance compliance. It is anticipated that dummies meeting the performance criteria of this document will be used in a wide variety of tests, requiring specialized test and data procedures.
Rationale: New testing has been completed that should be incorporated into the requirements for the pedestrian dummy. These tests include: thigh and leg tests, pelvis tests and whole body tests using a specified, standard generic car buck
