| 摘 要： | 抗鸟撞设计是飞机设计过程中一个复杂、关键的步骤.通过建立SPH-FEM耦合的鸟撞夹层结构数值计算模型，分析由常用的航空透明材料，如无机玻璃、聚氨酯（PU）、聚碳酸酯（PC）和聚甲基丙烯酸甲酯（PMMA）组合构成的夹层玻璃（板）风挡的鸟撞响应.PU、PC和PMMA的材料参数通过材料各自的准静态、动态试验结果得到.在有限元软件LS-DYNA中计算夹层结构的鸟撞过程，得到夹层结构的破坏失效过程，并分析不同材料组成的夹层结构的抗鸟撞性能.发现由无机玻璃和高分子聚合物组成的夹层结构的抗鸟撞性能最佳.

| Abstract: | Bird impact resistant design is a complex and key procedure in aircraft design. The coupling of smoothed particle hydrodynamics (SPH) with finite element method (FEM) was presented to model bird impacting on the laminated glass structure consisting of inorganic glass, polyurethane (PU), polycarbonate (PC) andpolymethyl methacrylate (PMMA). Material properties of the transparent material mentioned above were obtained by quasi-static and dynamic experiment result, respectively. The dynamic response of laminated glass structure with bird impact was obtained by simulations using the commercial software LS-DYNA. The damage and failure processes of laminated glass structure were observed and the bird impact resistance of laminated glass structure was analyzed. It is found that the structure consisting of inorganic glass and polymer has the best bird impact resistant performance. |
