摘　　要：针对金属燃油箱在设计阶段存在试验次数多、周期长等问题,文中提出了一种基于正交试验的设计方法来解决此类问题。该方法选取燃油箱的下箱体、隔板和上箱体3个因素,其中下箱体取8个水平,隔板及上箱体各取2个水平,按照L16(8×22)正交表设计了16种试验方案。通过结合有限元分析得到该结构的固有频率及通过极差分析研究各因素对燃油箱固有频率的影响,从而找出影响金属燃油箱固有频率的主要因素并确定其油箱设计的优选方案。结果表明,该方案的试验次数明显减少,设计周期缩短,验证了该方法的可行性。There are many problems in the design stage of fuel tank, such as many trials and long design period. For these issues, an orthogonal test method was proposed for the design of fuel tank. Three factors were selected such as the lower part,baffle and the upper part which can affect the fuel tank. The number of their level in turn as follows： 8,2 and 2. The sixteen kinds of test programs was designed by L16（8×22） orthogonal table. The natural frequency of fuel tank was obtained by finite element analysis, and the impact factors on the natural frequency were researched by range analysis. Then main factors which impact on the natural frequency were obtained, and the optimum program in the design of fuel tank was determined. The results show that the test times of the proposed program are significantly reduced, the design period is shortened, and the feasibility of the method is verified.
