Tractor-trailer Response to High Crosswinds; Static Computations and Dynamic Simulations 2007-01-4255

Tractor-trailer rollover due to high crosswinds is a well-recognized accident type. Some highway jurisdictions limit high-profile vehicle travel under certain weather conditions in certain locations to reduce the probability of rollover or other loss of control. The criteria for these travel limitations appear to be based upon analyses of very simple vehicle models.
The present paper examines the rollover potential of tractor-trailers in high crosswinds utilizing a sophisticated dynamic multi-mass vehicle model. This model was developed to study handling and collisions and includes the capability to account for aerodynamic forces.
