摘要

A numerical model allowing simulation of forklift truck dynamic behaviour has been developed and validated by INRS (Institut National de Recherche et de Securite) using data measured on a real truck. Measurements recorded during a test involving lateral partial tip-over (truck fitted with lateral outriggers) were used to define a reference dangerous driving situation. Based on these specific driving conditions, simulations were conducted by varying not only the forklift truck design and driving parameters, but also parameters relating to its tyres. Results show that the forward velocity of the forklift truck, its centre-of-gravity height, steering angle amplitude and the machine's lateral wheel base are the most sensitive parameters amongst those studied. Parameters comprising peak value D_y of lateral force and F_y cornering stiffness provided by the tyres appear to have little influence on forklift truck tip-over triggering conditions.
