Research on analysis and optimization design of coach roll-over based on FEM technology

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.
