The roof top of the bus will be the first structure to contact the ground and take the majority of impact load and energy when rolling-over. To ensure the safety of the passengers, several safety regulations are in place. This study focuses on the roll-over analysis of a midsize electric bus, and investigates its general safety performance. In the research, a midsize electric bus was built and set to simulate the roll-over condition according to the European regulation, Economic Commission for Europe (ECE) ECE R66. The commercial code, LS-Dyna software package, was used. The structure deformation, residual space, and over-all safety performances were evaluated. The results show that the designed structure of the midsize bus meets the required regulation. Further improvements can be made in the future studies.
