Cluster B

Coupling Shape-Air/Wind

Project Manager

Partners

Scania, Trafikverket, Bombardier Transportation, Creo Dynamics

Overall Goals

Throughout the project the main objective is to propose less wind sensitive vehicle designs, or rather avoid increased crosswind sensitivity even though the vehicles are made lighter. By making the vehicles lighter reduced energy consumption, greenhouse gas effects, external noise levels and track/road deterioration are anticipated. The less wind sensitive vehicle designs should be mainly achieved through alternative external shaping and suspension systems.

Functional Conflicts involved

1/ Power Generation – Engine cooling – Noise-Reduction

The use of an IC engine to generate power must be balanced against sufficient engine cooling and against low noise transmission.

2/ Light Weight Movement – Unsteady Aerodynamic Loading – Unsteady Motion Handling

Vehicles must balance light-weight low-energy movement against stability under unsteady aerodynamic loading, and against stable and smooth handling of cornering and varying surfaces.
