In recent years, due to the worsening of air pollution caused by the increase in automobile traffic and the soaring fuel prices, attention has been paid to ultra-compact mobility, including bicycles, worldwide. In particular, the market for shared mobility services that combine ultra-compact vehicles with public transportation is expanding rapidly. In response to this situation, we are working on the development of a foldable, small and safe electric three-wheeled mobility. In this research, I aim to support the practical application of shared mobility by introducing a suspension system as a countermeasure against vehicle rollovers. I used the multibody simulation software Adams to conduct dynamic analysis to evaluate the vehicle behavior during turning. Based on the simulation results, I selected an appropriate suspension that considered the combination of spring constant and suspension length. I installed the selected suspension on the actual vehicle. However, the load was not properly transmitted in the axial direction of the suspension, and the original expansion and contraction was not exerted, so it was found that the mounting part needed to be improved.
