Design, development and fabrication of chassis and suspension for four wheel electric scooter for handicapped for indoor and outdoor use

Abstract

This report aims to model, simulate, perform the static and dynamic analysis and fabrication of four wheel electric scooter chassis consisting of circular pipe and square beams. Modeling, simulation are performed using modeling software i.e. SOLIDWORKS and analysis on ANSYS. The maximum deflection is determined by performing static analysis and dynamic analysis. As we had to customize this scooter so it can be use for indoor purpose also so keeping in mind we had design our chassis. Strength and light weight were our basic consideration throughout the design of the chassis of electric scooter. Hence, AISI1018 was selected as an appropriate material for design which is medium carbon steel with properties such as light weight, high tensile strength, high machinability, better weldability, etc. All the impact and stresses were calculated manually by considering the severe working condition and then the design was analysed in the analysis software. Step by step modification in design we made as found necessary and as analysed on the software. After the complete analysis and the approval of design by inspecting it in all the modes of failure the design was finalized and was selected to fabricate which will not fail in any extreme criteria of stresses or load induced.
