Design and Optimization of Bicycle Frame for the Cyclist's Comfort

Abstract

Bicycle plays an inherent role in our life. Bicycle riding is a globally popular sport and an economic transportation. The performance of frame is depends on the weight of the bicycle and frame design. Optimization of weight and structure of the bicycle frame is the best scope of optimizing the overall performance of the bicycle. When the rider ridding bicycle on rough surface, the induced vibrations will cause the fatigue of its rider and the fracture of its frame structure. This paper deals with the study of the structural design, modal analysis and optimization of bicycle frame by using composite material with help of FEA. Firstly structural analysis, numerical results obtained by applying dynamic loading condition. Secondly, the Modal analysis is used to identify modes of bicycle frame to calculate natural frequencies and mode shapes by using Finite Element Analysis. Finally, the analyzed frames are then optimized to reduce weight without affecting their capacity to be resistant to mechanical stresses.
