A rollover vaulting algorithm (RVA) for simulating vehicle / barrier collision behaviour. Paper prepared for the 54th Annual Meeting of the Transportation Research Board TRB, Washington, D.C., January 1975.

Due to the relatively high center of gravity of most heavy vehicles, the possibility of rollover vaulting is always present when such a vehicles collides with a barrier. An improved rollover vaulting algorithm (RVA) has been developed. The RVA program can monitor: the angular orientation of the vehicle during and after the initial impact; the respective angular rates of the vehicle center of gravity during redirection; the trajectory of the magnitude of the initial impulse between vehicle and barrier; and the tire / suspension reaction forces during redirection of the vehicle.
