飞机壁板战伤修补方法的数值分析

Nnmerical studies on the battle damage repair technique for aircraft panels

在总结了飞机战伤模式和壁板战伤修补方法以及现有力学模型和有限元模型的基础上,提出了一种双壳—弹簧元模型,利用ANSYS的APDL(ANSYS参数化设计语言)编程对复合材料的单纯壁板修补极限强度进行了计算与分析,获得了一些有参考价值的结论。

Based on the existing computational models and finite element method（ FEM ） technique, presents a model named ＂ double shell - sjprtng＂, Based on the mopdel and APDL of ANSYS soffiware, the repair ultimate strength of single plate with composite material properties is studied. Some conclusions valuable in engineering are obtained in the paper from the results.
