QUASI STATIC ROLLOVER OF A RIGID VEHICLE The most rudimentary mechanics involved in rollover of a motor vehicle can be seen by consideringthebalance of forces on a rigid vehicle in cornering. By rigid vehicle it is meant that the deflections of the suspensions andtires will be neglected in the analysis. In a cornering maneuver the lateral forces act in the ground plane to counterbalance the lateral accelerationactingatthe CGof the vehicle, as shown in Figure 9.1. The difference in the position at which these forces act creates a moment on the vehicle, which attemptsto roll it toward the outside ofthe turn.
