In this work a full vehicle model of a rural transport vehicle (RTV) is developed in MADYMO. The steering, tyre and suspension are modeled using standard modules available in the package. A speed controller was also incorporated to maintain a constant speed of the vehicle in the simulations. Validation of the model was done against experimental accelerations measured over a bump. The validated model was then used to predict rollover characteristics using Slowly Increasing Steer, J-Turn, and Road Edge Recovery maneuvers. These maneuvers were conducted for three different loading conditions – RTV without passengers, RTV with unrestrained passengers, and RTV with restrained passengers – and the safe speeds are compared with those of other vehicles.
