摘要：

通过对单侧阶梯挖补修理的碳纤维环氧树脂/芳纶纸蜂窝板进行模态测试和有限元仿真，探究了挖补修理

复合材料蜂窝板（简称蜂窝修理板）在湿热环境下的振动特性。利用分段剪切变形理论和湿热等效理论建

立了单侧阶梯挖补蜂窝修理板的有限元模型；分析了在不同的湿热条件下，修理参数对蜂窝修理板固有频

率的影响。结果表明，挖补修理导致复合材料蜂窝板的刚度下降，挖补斜度越小，母板挖除越多，则蜂窝板

刚度越低，在湿热条件下，这种影响更为显著；在温度为 300~375 K、湿度为 0~0.75% 范围内，蜂窝修理板在

湿环境下固有频率降低比在热环境下明显；湿热联合作用对蜂窝修理板固有频率下降的影响比湿、热条件

单独作用的叠加更大。

Abstract:

Through the modal test and finite element simulation of the carbon fiber epoxy resin/Nomex paper honeycomb

panel which is one-side stepped scarf patch repaired, the vibration characteristics of the scarf patch repaired

composite honeycomb panel (abbreviated as honeycomb repaired panel) under hygrothermal conditions were

explored. Using the segmented shear deformation theory and the hygrothermal equivalent theory, a finite element

model for one-side stepped scarf patch honeycomb repaired panel was established. The effect of repairing parameters on the natural frequency of honeycomb repaired panel under different hygrothermal conditions was analyzed. The results showed that the stiffness of the composite honeycomb panels decreases due to scarf patch repairing, and the smaller the slope of scarf patch, the more the motherboard is removed, the lower the stiffness of

the honeycomb panels, and the effect is more significant under hygrothermal conditions. In the range of temperature from 300 K to 375 K and humidity from 0 to 0.75%, the natural frequency of honeycomb repaired panels decreases more significantly in hygroscopic conditions than that in thermal conditions. The combined effect of hygrothermal has a greater impact on the natural frequency reduction of honeycomb repaired panels than superposition of the separate effects of hygroscopic and thermal conditions.
