This study was conducted to verify the structural stability of the chassis frame of the Small electric low-floor bus. The chassis frame model was analyzed under its own weight and external loads to determine deformation and stress distribution. A finite element method (FEM)-based structural analysis was performed to verify the strength and durability of the chassis frame assembly components. The analysis results identified the maximum stress values and their locations throughout the system. Furthermore, considering the differences in materials used in each component, the maximum stress values for each component were individually calculated. Comparing the maximum stress values with the yield strength of each material confirmed the structural stability of the designed Small electric low-floor bus chassis frame.
