Development of a higher–order model for a roll simulator

A four degree–of–freedom model of a roll simulator is developed. The roll simulator consists of a sled–platform assembly, where a recreational off–highway vehicle (ROV) is mounted to the platform which has the freedom to rotate up to 90 degrees. The purpose of the roll simulator is to re–create rollover manoeuvres ascertained from in–field vehicle dynamic experiments. Previous studies developed a two degree–of–freedom model; one for translational and one for rotational motion. This study expands on that model and increases the number of degrees–of–freedom to more closely emulate the roll simulator. The model incorporates non–linear stiffness models of the wire ropes and enables the model to have three translational degrees–of–freedom and one rotational degree–of–freedom. The equations of motion (EOM) are numerically simulated using Matlab's Simulink. Comparisons are made with experimental data derived from the roll simulator to validate the model.
