Lift truck lateral tip overs are mostly caused by the intrinsic instability of this vehicle. The objective of this project was to develop a model to simulate various safety systems to assess driver's safety in lateral tip overs. A biomechanical model of a driver (50th percentile Hybrid III dummy), the interface with a lift truck, as well as four safety systems (lap belt, armrests, shoulder bolsters and doors) were developed using MADYMO software. Two different rollover conditions were simulated: at rest (0 km/h) and high speed (20 km/h). Velocities and accelerations of the dummy were used to assess simulation results. A realistic kinematic behavior of the models with each safety systems was obtained. Lap belt with shoulder bolsters seem more effective to improve driver's safety than lap belt alone or with armrests and doors, especially when the HIC (head injury criterion) is considered.
