Critical Comparisons of Responses Between Side Impact MDB and Pole Test Modes

This paper provides a detailed comparison of structural responses and their effect on occupant responses between the oblique pole and moving deformable barrier test modes, including the test protocol, dummies, and injury metrics. The temporal event sequences that take place in each of these test modes are presented in light of underlying physics and primary momentum exchanges. The key factors affecting dummy responses in each of these modes are identified and summarized. Additionally, the authors present a brief conceptual framework to understand overall vehicle and occupant dynamics. The analyses of vehicle effective mass, vehicle lateral stiffness and structural analysis are covered by vehicle crash dynamics using momentum and energy conservation for vehicle structure and structural response simulation design and development using subsystem test/CAE methodology. The focus of occupant dynamics is on analysis of a dummy's body regions, including the head, neck, thorax, pelvis, and upper leg, to better understand the effectiveness of side restraints such as airbags and to develop countermeasures.
