Abstract
This thesis focuses on the safety and performance analyses of disk-brake bicycles riding along straight and curved paths. Braking performance of a bicycle is undoubtedly the most important characteristics that may affect rider’s safety. The braking force mainly results from friction between tires ad road. As the bicycle riding along a curved path is under the exertion of braking force, lateral stability plays a major role for the bicycle’s safety. A simplified three dimensional model is adopted to investigate the dynamics of the bicycle as it is decelerating. It is found that the camber angle of the front wheel and the geometric configuration of the bicycle play a significant role on turning stability during braking. However, the height of the center of mass of the rider and bicycle does not affect bicycle riding stability. In this study criteria for evaluation of braking capability and methods for improvement of braking performance will be discussed.
