“…In 1995, computer simulations using ATB were reported by Cheng to predict passenger ejection and minimal driver impacts for a rollover accident [17,18]. In 1998, Renfroe et al used MADYMO to model a rollover crash test with dummies reporting good agreement between simulation and test [19]. Also in 1998, Friedman and Mobrem reported using finite element modeling with optimization to demonstrate improved roof strength [13].…”

The evaluation of the biomechanical performance that can be expected by restrained occupants from the incorporation of an intelligent rollover protection subsystem (IRPS) into a production vehicle has been conducted. This paper reports on the evaluation of such a system based on finite element modeling. Finite element models of vehicle designs and the Hybrid III dummy were used to evaluate the subsystem under manufacturer-created rollover conditions for a production roof structure. Results from a rollover crash test of a production vehicle were utilized to validate the model, using the production vehicle crash test. The IRPS design was then integrated with the production vehicle and the results were compared with the baseline neck biomechanical injury measures. Neck loads were utilized to validate the model against the test results. The results of the study show that the IRPS resulted in substantial reduction of head and neck loads with the production roof and even greater reductions with a strengthened roof. The results illustrate opportunities available to improve rollover crashworthiness performance for restrained occupants.

“…None of these are rollover finite-element models. However, it has to be mentioned that several vehicle rollovers have been modelled and validated in rigid lump mass body codes such as EDVSM, ADAMS and MADYMO [9][10][11][12].…”

Vehicle crashes often involve rollover. A vehicle rollover is a complex, 3-dimensional event that is quite difficult to model successfully. As a result, crash investigators often make simplifying assumptions that compromise the quality of the information learned from the analysis. Advances in vehicle simulation modeling have greatly reduced the amount of work required to perform rollover simulations. Rollover simulation holds promise as a tool to learn more about crashes involving rollover. This paper describes how the EDVSM simulation model calculates 3-dimensional forces and moments on the sprung mass (i.e., body exterior) and how these forces and moments are integrated into the equations of motion. The paper also provides some examples of the use of rollover simulation. Finally, the paper addresses the practical and theoretical limitations of rollover simulation as a tool for routine reconstruction of on-road and off-road crashes. Evidence Analysis Numerous researchers have presented papers describing how to interpret the crash site and vehicle-related artifacts from rollover crashes. Orlowski [3], Martinez [4] and Marine [5] provide examples of such research. A discussion of maneuvers leading to rollover and procedures for testing rollover propensity are also presented.
