Abstract

The frame structure of a bus is designed to withstand the weight of the overall vehicle and impact force when involved in an accident. An analysis is required to ensure the design of the structure complies with the international safety requirements and regulations of the United Nations Economic Commission for Europe Regulation No. 66 (UNECE R66) for passenger bus. The analysis of the electric bus structure is crucial because the structure configuration has changed due to the difference of parts and components between traditional gas-powered buses and electric buses. The roll-over crash analysis of the bus is performed to determine whether the structure can deform and collapse without intruding the residual space of the bus. The finite element method is utilized to determine the crashworthiness and strength of the bus structure. The model of the bus structure is created in SOLIDWORKS software and ABAQUS software was used to perform the roll over crash simulation. Angular velocity was applied onto the bus structure along with boundary conditions that represent actual roll-over crash. Stress and deformation contour plots are analysed to determine the strength and survival space of the structure. This project attempts to develop an electric bus structure that complies with safety regulations.
