Finite element analysis of a titanium bicycle frame

Bicycle has been emerging as an ideal means of transport thanks to its sustainability. This study investigates the structural integrity of a titanium bicycle frame using the finite element method. The analysis focuses on a loading condition based on the BS EN ISO 4210-6 standard and consists of a tensile force of 1200 N applied at the front axle, which corresponds to the maximum force specified in the standard for fatigue testing. The results revealed that the areas of the top and down tubes near the head tube are the most stressed, with the stresses exceeding the material ultimate tensile strength. The study highlights the potentiality of optimizing bicycle frame design by using finite element results for predicting both static and fatigue strength.
