摘　　要：为了研究汽车塑料燃油箱正常工作时的结构性能,建立燃油箱有限元分析模型,并利用Abaqus软件分析燃油箱内部受到不同极限压力时的应力及变形情况,试验结果验证了有限元模型的正确性.结果表明,燃油箱在内部承受极限正压力35 kPa时,其表面最大应力为8.977 MPa,最大变形为18.77 mm.For studying the structural performance of automotive plastic fuel tank during normal operation,a fuel tank finite element analysis model is established.And Abaqus software is used to analyze the stress and deformation of the fuel tank under different ultimate pressures.The test results verify the correctness of the finite element model.The results show that when the fuel tank is subjected to the ultimate positive pressure of 35 kPa,the maximum stress of tank surface is 8.977 MPa and the maximum deformation is 18.77 mm.
