Recent advancement on testing and modelling methodologies in rollover analysis

Rollover crashes are the most complicated and yet least understood incidents among all the vehicle crashes. Many rollover safety research projects have been conducted experimentally and analytically to investigate the underlying principles and causes of vehicle accidents and develop rollover test procedures, test methodologies and Computer Aided Engineering (CAE)-based rollover models to evaluate the nature of rollover crash events pertaining to both vehicle and occupant kinematics. Studies of the vehicle and/or occupant kinematics during rollover crashes, in turn, help to understand occupant injury mechanisms for developing countermeasures towards improved rollover occupant protection. In recent years, many significant advances in rollover safety researches have been made towards better rollover safety. This paper reviews some recent progress on rollover research in the literature. Future trends and potential needs in rollover analysis are presented based on reviews of these state-of-the-art technological and methodological progressions on rollover safety.
