Utilization of carbon fibre for construction of elastic elements of mountain bike rear triangle
Linda, Jakub ; Švancara, Pavel (referee) ; Březina, Lukáš (advisor)
The aim of the thesis is to design a carbon elastic element in the suspension mechanism of the rear wheel of a mountain bike. The elastic element will replace the rotary link and its deformation will allow movement of the rear wheel suspension mechanism. At the beginning, the thesis deals with the theoretical introduction to bicycle geometry, types of rear wheel suspension mechanisms and their characteristics. Later on, the work is devoted to composite materials in general, and it also deals with methods of manufacturing a composite bicycle frame and deals with the mechanics of composites. Further, the thesis is focused on the research of already existing frames utilizing the flexible element in the suspension mechanism of the rear wheel. Finally, the work focuses on the design of a full-suspension bicycle using a flexible element, justifies the choice of the replaced suspension mechanism and also justifies the individual simplifying assumptions and their impact on the solution. The elastic element is analyzed for deformations and stresses in the Ansys software. Finally, the results of the analysis and recommendations are presented.
