Structural and modal Analysis of Scooter Frame for Design Improvement

This paper discusses the stress and deformation developed in chassis during the different load cases and identifying the failure modes by the modal analysis. It starts from the benchmark study of different scooter frame in the aspect of material selection, mechanical properties and the sections used in it (usually circle section is preferred because of its easiness of manufacturing, even load distribution for different load cases and some other geometrical reasons). Then Structural and modal analysis of frame were carried out under the various load considerations. It involves 3D modeling in Pro-E, meshing in HyperMesh and analysis by ANSYS. Hence the following works are completed. Viz (i) Validation of the Frame design i.e. stress and deformation calculation using FEA and suggest the design recommendations, (ii) Bench mark study of the frame structure, load characteristics, metallurgical and mechanical properties of the scooter frame members and (iii) Identification of critical stress areas and suggest for design improvement from the Modal analysis by identifying the different mode shapes and Natural frequency of the frame.
