Experimental testing and numerical modelling of an electric scooter

The growth of e-scooter users on the urban micromobility over the past years has been such that the study of this vehicle is gaining more and more importance thus opening many branches of study. This paper intends to present a detailed study of the user comfort while riding an electric scooter through an exhaustive experimentation and the consequent creation of a mathematical model that simulates the e-scooter dynamics. The thesis is organized as follows. First, a thorough overview of the electric scooter will be presented. This contains a definition of the vehicle with an enumeration of its advantages and disadvantages, a brief story of its evolution, a comparison with other powered micromobility devices, a depiction of the different elements that form an e-scooter and a description of the specific model used throughout the study. Second, an explanation of the experiments carried out and the aim of every and each of them is detailed. While one of the experiments allowed to study the influence of the vibration on human comfort, another one permitted to study the vehicle’s braking response. On the other hand, a couple of other tests helped to create the mathematical model. Next, an explanation of the data acquisition system can be found. Ok The data acquirement was done thanks to the proper configuration of a SCADA-XS device and the appropriate disposition of the sensors: a GPS and four accelerometers. Afterwards, a preliminary study followed by an in-depth analysis are deeply exposed. Meanwhile the first one verified the rightfulness of the data acquired by the sensors to later process it, the second one post-processed the data by varying the survey according to the final aim of the corresponding experiment. Last but not least, the mathematical model created thanks to the data extracted from the study is showcased. Finally, conclusions from this research are drawn. delling of an electric scooter
