摘　　要：目前金属油箱因为其技术成熟,结构简单的特点,在汽车领域中广泛应用。在对乘用车油箱的设计过程中,应用有限元技术对油箱进行结构强度分析,主要考虑油箱在半箱油时,车辆行驶颠簸产生的冲击力来校核其强度。按保守强度设计要求,结合企业设计经验,取3倍半箱油重量作用时的静态强度来校核其颠簸产生的冲击力。同时对油箱关键点进行应力应变电测试验,将实验结果与有限元分析计算相结合,探索出适合油箱结构强度设计的理论与实践相结合的方法。The metal tank because of its mature technology,the characteristics of simple structure,has been widely used in automobile industry.For the design process of passenger car fuel tank,it applies finite element techniques for structural strength analysis of fuel tank,considers a half tank of oil in the tank,and takes the impact force generated by the vehicle bumps to check the strength.According to conservative strength design requirements,combined with corporate design experience,takes static strength in three times the weight of half a tank with oil to check the impact force generated by bumps.Makes a stress-strain electrical experiment on the key points of fuel tank,combines experimental results with finite element analysis,and explores a suitable method that combined theory with practice of the fuel tank structural strength design.
