Personalized Virtual Non-round Bicycle Chain-rings using Live Optimization While Pedaling

The TrueBike, a cycling trainer that mimics the forces felt when accelerating, grade changes, and wind drag.

Overall objective: Personalized non-round chainrings based on real-time optimization of the shape of a (virtual) chainring

Research options:

  • Collect, review, discuss available research of non-round chainrings
  • Establish a penalty function that would have to be minimized during the optimization. Penalty function can be related to muscle activation, speed variations, multibody analysis, etc
  • Develop an optimization algorithm that modifies the chainrings whilst cycling
  • Develop a measurement protocol to find the optimal chainring for an individual. The form of the chainring will influence fatigue and muscle contraction speed, leading to new optimal chainrings
