| Advanced analysis of a bicycle frame for competitive advantages are investigated using I-DEAS simulation and parametric modeling capabilities with the goal of discovering ways to optimize frame performance. Since, performance is enhanced by minimizing weight and simultaneously optimizing directional flexibility, the analysis focused on scrutinizing strain energy distribution in each member of the structure to discover ways to specifically bias the stiffness characteristics for meaningful boundary conditions. In addition to solid and shell finite element analysis capabilities, I-DEAS facilitates extensive beam analysis options that are utilized in extracting member forces, which are analyzed analytically in terms of classical strain energy relations and graphed to depict how each forces mode contributes to the energy absorption and load path distribution. The results are insights into how load paths behave with various boundary conditions that lead to how one may modify each member to achieve flexibility for reducing fatigue during long rides or reducing excess frame flexing during competitive acceleration events. Additionally, the various studies provide an outstanding base for initiating a composite frame design. |
