Design and Modeling of a Compact Lightweight Electric-Scooter

Over the past several years, the conventional methods of fueling the two-wheelers led to the challenging issues for the environment. To minimize such issues, electric (e-) scooters are being explored nowadays by the industries and research organizations. Moreover, e-scooters, as a green technology, can also be a cost-effective solution in case of high fuel prices. Therefore, in this work, the design and modeling of an electric scooter is presented. Primarily, design features and specifications for the major components of an e-scooter are evaluated. Based on the design specifications, a CAD of the e-scooter is proposed in SolidWorks software with and without bodyworks. Thereafter, material specifications and boundary conditions are discussed for chassis under operating load and sudden impact load scenarios. The finite element analysis results are shown to estimate the maximum Von-Mises stress, maximum displacement, and minimum factor of safety (FOS). The dynamic analysis is carried out by estimating the variation of motor torque and power with respect to its angular speed. Furthermore, the variation of aerodynamic force versus e-scooter velocity and rolling resistance versus total carrying weight is investigated. The static and dynamic analysis presents the promising strength, safety, and cost-effectiveness features of the proposed design.
