Abstract
Improving occupant survivability during a rollover accident requires a detailed analysis of the dynamics and statistical significance of a particular rollover situation as well as the structural performance of the vehicle involved. A two-dimensional model describing vehicle rollover has been developed which, in conjunction with a proposed index of performance, allows such an evaluation. Dynamic equations of motion for ground contact and airborne travel are used in the model which is programmed for solution on a digital computer. The model is validated by comparison of a graphics console display of the model trajectory with filmed sequences of a vehicle rollover. Validation of the model establishes the feasibility of this approach for predicting the rollover characteristics of a vehicle and determining relative safety performance between vehicles.
