Two-Dimensional Topology Optimization of Headtube in Electric Scooter Considering Multiple Loads

Year: 2025

Type: article

Abstract: The safety and structural integrity of electric scooters have gained considerable attention owing to their increasing use in personal mobility and the associated accident rates. This study applied topology optimization to the headtube of an electric scooter, which is a critical component susceptible to structural failure under diverse load conditions. A finite element model was developed to simulate the behavior of the headtube under 16 single-load conditions, followed by optimization for multiple loads. The optimized design demonstrated an enhanced material distribution, balancing the lightweight construction and structural robustness. Collision performance analysis revealed an improvement of at least 51% in the strain energy distribution compared with that of existing commercial models. These results underscore the potential efficacy of topology optimization in enhancing the safety and reliability of personal mobility devices. Moreover, topology optimization can provide a systematic framework for designing critical structural components.
