　　Based on the ECE R66 standard, a FEM model of a school bus was established and the rollover crash was simulated by LS-DYNA.According to the inbreak criterion of living space and the deformation level of side vertical beams, the side vertical beams and top arch beams were redesigned to make them light and safe.It was proved that the redesign can guarantee the safety of rollover crash and reduce the weight of whole bussimultaneously.
