摘　　要：侧翻是客车交通事故的主要形态之一,其耐撞性设计是产品开发过程中不可或缺的内容。通过建立某客车侧翻有限元模型并求解计算,分析和评价其侧翻安全性能,提出相应改进设计,经数值仿真对比,验证了改进设计的正确性。研究结果表明,对客车的设计、生产以及安全性评价具有一定指导作用。Roll-over is one of the main traffic accident forms for coach,its crashworthiness design is an essential process of product development.The Finite Element Model（FEM）of coach roll-over is established for safety research,and some improvement measures were proposed also after FEM analysis,finally,the improvement measures were verified resonable by FEM analysis.The research achievement is useful for the design、manufacture of coach in practice.
