Design, development of suspension and steering system for four wheel electric scooter for handicapped for indoor and outdoor use

Abstract

This report aims to the design, development and improvement of four-wheel electric scooter suspension and steering systems. The improvements in the existing project is made based on certain predefined problems and are considered in reference to the comfort of the handicapped. The maximum deflection is determined by performing static analysis and dynamic analysis. Moreover, it has been specifically designed for a particular patient who is disabled by lower limbs. Therefore, we have made it customized that is according to the patient body dimensions, needs or requirements. As we had to customize this scooter so it can be used for indoor purpose also so keeping in mind, we had considered the comfort of the driver as our key motto and accordingly we researched on not only one but we considered three varieties of suspension. All the impact and stresses were calculated manually by considering the severe working condition and then the design will be analyzed in the analysis software. Step by step modification in design we made as found necessary. After the complete analysis and the approval of design by inspecting it in all the modes of failure the design was finalized the suitable system.
