摘　　要：将新型板翅式夹芯结构应用于车载LNG储罐外筒体强化,通过正交试验法对板翅式夹芯结构的翅厚、翅高、翅宽、上/下板厚度与宽度进行分析,并通过Matlab优化工具箱的Fmincon函数对板翅式夹芯结构进行优化。结果表明:影响板翅式夹芯结构刚度的主要因素是翅高和板宽,其他因素次之。优化后的板翅式夹芯结构刚度与原有角钢加强筋相当,但是较加强筋高度降低8mm,车载LNG罐车装载体积增大了约0.7m3。The plate-fin sandwich structure which boasting of compactness and high stiffness was used for LNG tank＇ s outer reinforcement. Applying orthogonal test to analyzing both fin＇ s thickness, height and width and upper and lower plate＇ s thickness and width, then employing the Fmincon function in Matlab optimization toolbox to analyze plate-fin sandwich structure show that the fin＇ s height and width mainly influences the plate-fin sandwich structure＇ s stiffness, and other factors only take second place ; the optimized plate-fin sand- wich structure and angle steel used in LNG tank have the same stiffness, and the height of reinforcing rib can be reduced by 8mm, this has LNG tank＇ s loading volume increased by 0.7m3.
