Motion Analysis and Signal Processing for Analysis of Bicycles

We execute dynamic motion-analyses of high performance road racing bicycles featuring carbon frames. We achieve our goal by measurements of numerous and different wireless sensor nodes and subsequent signal analysis.

Contexte initial

We capture different variables describing the racing bicycle and its rider to get a complete picture: 3D accelerations at frame positions, pedal frequency, pedal force, GPS position, and heart rate. The physical variables are captured at various positions of the bike. Thereto we develop tiny autonomous sensor nodes which communicate wirelessly. The data analysis will deliver design details to optimize the frame construction.

But

The project explores the relation between statically and dynamically determined frame stiffnesses and their impact on traction and rider's comfort.

Compétences clés

Investigtion and analysis of hardware algorithms for motion analysis and signal processing (for improvement of bicycle frame construction)

Perspectives

The infrastructure in development is the basis for a comprehensive gauging of bike and its rider. We expect novel characterization variables for the bike construction with respect to ride efficiency and comfort.
