DoVE — Development of Vehicle Exteriors

DoVE explored automated design of 3D aerodynamic objects. Using velomobile bodywork as a testbed, the project developed methods for evolving stable, lightweight, aerodynamically efficient shapes — without relying on expert engineering knowledge.

Why velomobiles?

The velomobile design community is driven by hobbyists and small companies whose trial-and-error process has produced highly non-intuitive but outstanding shapes (e.g., the Milan velomobile). This suggests a large, unexplored design space that conventional engineering intuition cannot reach — a perfect target for evolutionary exploration.

Technical approach

  • Neural indirect encodings (CPPNs/HyperNEAT) — evolved to generate entire 3D geometries holistically, allowing non-local, highly complex shape changes
  • Techniques originally developed for evolving large neural networks, repurposed for 3D form generation
  • Integration with CFD evaluation for fitness assessment

DoVE-Tales: Real-World Drag Testing

A second strand extracted aerodynamic models from real-world footage:

  • Tufts (yarn/wool indicators) attached to aerodynamic base shapes
  • Computer vision analysis of tuft position, orientation, and deformation over time
  • ML models deriving full quantitative aerodynamic characterisation from tuft behaviour
  • Enabling realistic comparison tests and design analysis under actual road conditions
