Rollovers are the second most dangerous type of crash occurring on our nation’s highway. Rollover during cornering is one of the most important concerns as far as safety of sports utility vehicles and trucks. Static stability factor, which is the ratio of vehicle track width and twice the height of center of gravity, is used as a parameter to determine the rollover performance of a vehicle. But static stability factor ignores many dynamic factors which may be important in improving rollover performance. The objective of this study was to consider dynamic parameters that affect rollovers. There dynamic factors are cornering stiffness, roll stiffness, tire properties, fore/aft location, center of gravity above ground and track width. Vehicle dynamics and ride analysis equations were analytically and numerically studied to analyze the factors, responsible for rollovers. A 1/10th scale model remote controlled (R/C) car was used to perform design of experiments (DOE) analysis of the roll angle as affected factor variations. The factors varied included front and rear suspension stiffness, track width, tire stiffness, center of gravity height and fore/aft locations. The R/C car was customized to allow adjustments for the factors. An ultrasonic sensor was used to measure the distance above the ground under dynamic behavior of the car. A total of 33randomized runs were conducted for a fishhook test maneuver. Finally, a design of experiment (DOE) analysis was performed to analyze the effect of each parameter on the roll tendency and settings which maximize and minimize roll tendency are presented. The results were compared with ADAMSTM simulation software, to further enhance the study and to present an in depth-over-view of the key vehicle parameters affecting propensity of rollovers.
