| 目的 研究飞机尾翼结构采用芳纶纤维复合材料的抗鸟撞性能。方法 根据芳纶纤维夹芯和芳纶纤维层合板两种飞机尾翼前缘构型，分别建立有限元模型进行仿真计算，分析两种构型鸟撞后的损伤和变形，并对两种构型进行抗鸟撞性能研究试验。结果 芳纶夹芯前缘构型前缘凹陷，前梁没有破裂；芳纶层合板前缘构型前缘破裂，前梁有破损。试验结果与仿真分析结果高度吻合。结论 芳纶夹芯前缘构型比芳纶层合板前缘构型具有更好的抗鸟撞性能。芳纶纤维层合板构型会造成前缘蒙皮变形过大，前梁腹板破损，导致飞机鸟撞后维修成本较高。 |
| 英文摘要: |
| The paper aims to research the bird strike resistance of empennage using aramid fiber.According to the two types of empennage leading edge based on foam sandwich structure and laminate structure both using aramid fiber, the finite element models of empennage structure were simulated to analyze damage and deformation and test the bird strike resistance of the two structures. The leading edge of foam sandwich structure was depressed and the fore beam was not broken. The leading edge of laminate structure and the fore beam both were broken. The test result was in good agreement with simulation.The foam sandwich structure has better effect of bird strike resistance. The laminate structure has higher maintenance cost because of overlarge deformation of leading edge skin and damage of fore beam web. |
