Abstract [en]

Improvements in vehicle technologies in recent decades enable the use of lighter materials and the development of control systems for autonomous vehicles. However, these improvements lead to a need for better understanding of how flow phenomena affect crosswind stability of ground vehicles which will enable the design of the less wind-sensitive vehicles. Therefore, the present study investigates the significance of roll on the dynamics of ground vehicles subjected to crosswind gusts. It includes a multidisciplinary approach in which there is a two-way coupled simulation between aerodynamics and vehicle dynamics equations. As a result of the investigations, significant differences have been found be- tween the computations considering no-roll and roll motions.
