Design Improvement of the Handle bar Assembly of an Automobile Using FEA

Designing the handle bar assembly of a two wheeler holds many challenges together with valuation of the structural strength of the mating components. While the handle bar is subjected to buckling, the housing and the other frame experiences tensile, compressive and shear stress. The situations during braking and the forces generated due to road bumps and pot holes can increases the problem. This work shall focus on conducting linear stress analysis while evaluating and rationalizing the loads. Finite element analysis of handle bar assembly is carried out using Altair solver code RADIOSS. In this study the handle bar assembly is excited with acceleration obtained from road load data to evaluate the strength of mountings on handle-bar. Model is prepared using Catia V5R20, Pre processer Hyper Mesh and Post processing is done using Hyper View. The Finite element analysis outcomes are also well allied by the experimental results in which failure site and pattern is accurately matched. Further modifications have been made in design to come across the strength requirement.
