摘　　要：对含踏板燃油箱模型在踩踏工况下进行了静力的结构分析,并进行疲劳分析。选取箱体、踏板、端盖、支架、防浪板的厚度为设计变量,以质量、应力、变形、疲劳寿命为目标,对燃油箱进行优化设计,结果表明:优化后燃油箱的最大应力降低了4.29%,最大变形降低了13.04%,疲劳寿命提高了26.94%,质量降低了10.93%。Static structure analysis was carried out for the fuel tank model with a pedal under the tram-pling condition,and fatigue analysis was conducted.The thicknesses of the tank body,pedal,end cover,bracket,and anti-wave plate were selected as the design variables,with mass,stress,deformation,and fatigue life set as the goals.The fuel tank was thus optimized.The experimental results indicate that the maximum stress of the optimized fuel tank decreases by 4.29%;the maximum deformation decreases by 13.04%;the fatigue life increases by 26.94%,and the mass decreases by 10.93%.
