No . 436 - O The Importance of Dynamic Testing in Determining the Yaw Stability

This paper proposes a methodology that allows the combination of the Stability Factor and handling characteristic to predict the probability of rollover per single vehicle crash. Paper No.202-O Simulation of Occupant Kinematics in Vehicle Rollover Dummy Model versus Human Model Norbert Praxl, Markus Schönpflug, Jiri Adamec Institute for Legal Medicine Munich, Germany Abstract Currently, 25% of all automobile crashes with severe injuries are rollover crashes and the incidence of this particular accident type even shows an upward tendency (e.g. Minivans, MPVs). Therefore, there is a great potential of injury reduction in that area. Available dummies are designed and validated for impacts but not for complex kinematics. Existing human models with flexible spine and realistic joints should provide a better biofidelity than dummies. Therefore the main objective of the investigation is to compare dummy and human model in standard rollover crashes.

Paper No.231-O Crash Attributes that Influence the Severity of Rollover Crashes Kennerly Digges, Ana Maria Eigen National Crash Analysis Center, The George Washington University United States Abstract This analysis examines restrained and unrestrained occupants in crashes with and without ejections. It investigates cars, pickups, vans and SUV's as separate classes. The relative severity of single vehicle vs. multi vehicle rollover crash events is examined. Other crash severity variables evaluated include the number of quarter turns, the number of roof contacts, and the extent of vehicle damage.This analysis examines restrained and unrestrained occupants in crashes with and without ejections.

Paper No.236-O MADYMO Modeling Method of Rollover Event and Occupant Behavior in Each Rollover Initiation Type Hideo Takagi, Akihisa Maruyama Nissan Motor Co., Ltd. Koichi Kawaguchi TNO-Automotive Japan Jeff Dix, Nissan Technical Center North America Inc. United States Abstract There are many initiation events that can cause a vehicle rollover, and the occupant behavior is different for each type of rollover initiation. Therefore it is necessary to understand the differences in occupant behavior for each type of rollover. This paper describes a MADYMO modeling method used to study occupant kinematics in various rollover events that was developed using vehicle rollover research test data.There are many initiation events that can cause a vehicle rollover, and the occupant behavior is different for each type of rollover initiation.
