Characteristics Analysis of CVT with Built-in Crank for Bicycle

Abstract Bicycle is one of the most popular mode of transport due to the increase of interest in the well-being andenvironment pollution. Before fabricating a continuously variable transmission that is applied to the actual bicycle,for reducing the problems in the early stage, the reliable simulation program has been applied and the financial problem can be solved. In this paper, in order to confirm the design factor, the stress analysis has been applied. In all models, each link and the joint portion are assumed to be a major design factors, and impact of each link andjoints received stress during the operation and it is confirmed by using the CAE. Also, for the analysis region, thespecial code has been developed to calculate pulsation phenomenon through appropriate mathematical modeling.
