Impact of transition design on the accuracy of velodrome models
This work outlines the creation of a model of a velodrome datum line constructed from two straights, two circular-arc bends, and four transition curves. Different transition curve options are outlined and contrasted with a model with no transition curves. The influence of velodrome geometry on the wheel speed, wheel acceleration, roll angle, roll rate, and power demand of a theoretical cyclist is presented. The results display similar wheel speeds and roll angles for different transition curves, with larger differences when compared to the no-transition-curve option. Greater differences are observed in the acceleration and roll rate, for which calculations are only possible when using a transition curve. Comparisons of the model with theodolite measurements of two velodromes show a mean minimum root mean square error of 0.0398 m. This work can be used to increase the accuracy of existing track-cycling analytic models.
