Abstract

The aim of the project is to investigate the full dynamic characteristics of ground vehicles exposed to unsteady crosswind gusts. There is a need for improved understanding of how flow phenomena affect crosswind stability of vehicles, particularly with the introduction of lighter materials and the development of control systems for autonomous vehicles. This inherently requires a multidisciplinary coupling between aerodynamics and vehicle dynamics, including driver models. The proposed work will use two-way coupled aerodynamic and vehicle-dynamic numerical simulations and aims to provide a development tool that reliably predicts crosswind stability.
