Juan David Cano-Moreno, José Manuel Arenas Reina, Victorina del Carmen Parra Lanillos, Manuel Enrique Islán Marcos
TL;DR
This paper studies how e-scooter frame design affects rider comfort by analyzing vibrations and proposes a design guide to reduce them.
Contribution
The paper introduces a design guide for e-scooter frames to reduce vibrations and improve comfort based on mass geometry parameters.
Findings
Dynamic simulations showed that mass geometry parameters significantly influence e-scooter vibrations.
Application cases demonstrated comfort improvements of over 9% compared to the reference model.
A basic sensor and comfort color scale were proposed to provide real-time feedback to riders.
Abstract
E-scooter vibrations are a problem recently studied. Theoretical models based on dynamic simulations and also real measurements have confirmed the high impact of e-scooter vibrations on driver comfort and health. Some authors recommend improving e-scooter damping systems, including tyres. However, it has not been suggested nor has any research been published studying how to improve e-scooter frame design for reducing driver vibrations and improving comfort. In this paper, we have modelled a real e-scooter to have a reference. Then, we have developed a multibody dynamic model for running dynamic simulations studying the influence of mass geometry parameters of the e-scooter frame (mass, centre of gravity and inertia moment). Acceleration results have been analysed based on the UNE-2631 standard for obtaining comfort values. Based on results, a qualitative e-scooter frame design guide for…
