Development of Multiple Crash Events to Understand Occupant Behavior and Injury Based on Real-World Accidents SC18-22-0003
Abstract - Approximately a quarter of automobile accidents in the United States involve multiple impacts, but no standard test methodologies exist for the evaluation of these types of events. In this study, four categories were used for the selection of multiple crash scenarios, resulting in ten representatives of multiple scenarios. NASS-CDS was analyzed to determine the types and percentages of multiple crash accidents. Simulation was conducted with variable such as initial velocity of each vehicle, and items such as overlap and angle between vehicles. And it was used determine the final test conditions. The review of the test results, indicated different vehicle dynamics, vehicle damage and occupant kinematics compared with NCAP test modes. This data can be helpful to understand how the severe accidents are happening and how the occupants move and are injured inside the vehicle in which accidents are occurring in the field.
