Important results from the project
The purpose of the project is to investigate dynamic characteristics of ground vehicles which are subjected to crosswind gusts by using coupled numerical simulations of aerodynamics and vehicle dynamics including driver model. Results of the project include detailed understanding of crosswind sensitivity of vehicles providing a numerical tool that reliably predicts crosswind sensitivity of vehicles in order to design less wind-sensitive vehicles at early stages of their design processes.
Expected long term effects
Results present that consideration of the roll motion is essential in the crosswind analysis. Delay time in the steering input together with driver’s expertise is critical to overcome effects of the crosswind on vehicles. Driver efforts to alleviate effects of crosswind increase for crosswind lengths between 1.5 and 7 times the length of the vehicle. The results obtained improve state of art knowledge on the crosswind sensitivity of vehicles. They are expected to have impacts on the development of lateral disturbance compensation algorithms for autonomous vehicles.
Approach and implementation
The project studies were implemented according to its work packages as given in work plan. The results have been disseminated through conference and journal papers together with public engagement activities. Accordingly, two conference papers have been prepared, one is published and the other one is submitted. Three journal papers are also prepared, one is submitted and the other two are prepared and will be submitted soon. Besides, six public engagement and five training activities were conducted. The project activities are published on, www.crosswind.gen.tr.
