DEVELOPMENT OF AN APPROACH TO THE DESIGN AND CALCULATION OF AN AIRLESS WHEEL FOR AN ELECTRIC SCOOTER

Abstract

A method for calculating an airless wheel of an electric scooter based on a systematic approach is proposed. The developed hierarchical model of the "Airless wheel" system allows to conclude that when modeling that system, it is inexpedient to create one universal model that could reproduce both the action of the system as a whole and its individual subsystems. An analysis of an airless wheel as a mechanical system is carried out, taking into account the external loading, the presented design loads and stiffness of an airless wheel and a substantiation of its design, a method for choosing the design parameters of the spokes of an airless wheel of an electric scooter is proposed, and the design of an airless wheel using finite elements. The above dependences take into account both the design parameters of the scooter and the shock absorber used, and the driver's weight can be used when the airless wheel is loaded, which combines the functions of its own wheel and the shock absorber, and when developing methods for comparative experimental studies of airless wheels for scooters. The developed three-dimensional mathematical model of an airless electric scooter wheel using the discrete-continuous finite element method with an orientation to the tetrahedral formula of the elements and the fragmentation of the original area, completed in the Solidworks software package.     &nbsp
