Rollover Crash Analysis of the RTV Using Madymo

A full vehicle model of the Rural Transport Vehicle (RTV) is developed in MADYMO including steering, tire and suspension. A torque controller is simulated to maintain set speed of the RTV in simulations. The suspension characteristics were validated using experimental accelerations measured over bumps. The model is used to predict rollover limits using Slowly Increasing Steer, J-Turn, and Road Edge Recovery maneuvers. The rollover limits under three different loading states, RTV without passengers, with unrestrained and with restrained passengers have been studied.
