摘　　要：以弹塑性理论和有限元法为基础,运用ANSYS有限元分析软件对制导航弹进行了有限元建模与计算,得到并分析了其在冲击作用下的应力集中部位及应力值。为结构的进一步改进提供了理论依据,对航弹的设计有一定的参考价值。On the basis of elastic-plastic theory and finite element method, the software ANSYS is employed to carry out a finite element modeling and analysis for a guided bomb. The effective stress in the guided bomb＇s stress concentration zone is evaluated. Some useful conclusions are gained for the improvement of this structure. This study can be of some assistance in the design of guided bomb.
