Strength and Stiffness Optimization of Diamond Frame using Corrugated Tube

Abstract

Road bicycles form an intrinsic part of economic transportation. The overall efficiency and performance depend solely on the weight and frame structure. The benchmarks for an innovative frame design are kept in terms of lightweight, fatigue failure, lateral stiffness, torsional stiffness, impact forces and loading capabilities. The deformation and propulsion of bicycle consume rider’s energy, a reduction in deformation and mass of the frame is therefore necessary. In the present work, the structural design and a quasi static vertical load analysis of the bicycle frame are presented using finite element analysis. Corrugated tubes are introduced into the main triangle with different sets of combination and the numerical result thus obtained was compared against the standard tubular bicycle frame.
