摘　　要：某车型在开发阶段燃油箱晃动耐久台架试验过程中,油箱内部防浪板发生断裂。本文基于晃动耐久台架试验结果、线性疲劳损伤理论与nCode技术,利用简化后的力学模型进行分析,找到问题原因。经结构优化、CAE校核通过后,实物顺利通过晃动耐久试验,从而解决油箱防浪板断裂问题,为问题的解决提升了效率。The baffler of fuel tank was broken when doing fuel tank slosh durability test in the development in one vehicle program。This text was based on result of the fuel tank slosh durability test , linear fatigue damage theory and nCode Technology, using the simplified mechanical model to find out the cause of problem. After structure optimization and CAE checking,the baffler sample passed the fuel tank slosh durability test . The problem of broken baffler was solved ,and the experience enhance the efficiency of problem solving.
