| 摘 要： | 建立了某型预警飞机机头ESM天线罩有限元数值模型，对机头ESM天线罩结构进行了静态应力分析，得到了机头ESM天线罩受力情况，同时进行了机载天线罩模态分析以及响应计算。算例表明，罩体与机身对接约束附近区域应力最大，变形较大的区域集中在两肩附近，受撞击时有明显的局部振动，减小两肩附近的蜂窝尺寸可以改善天线罩的稳定性。

| Abstract: | In this paper,finite element modeling of the aircraft ESM-Nose is built and state characteristic analysis of the aircraft ESM-Nose is carried out with the finite element methods.The stresses under different loads are obtained.At the same time,the modal analysis and response analysis are calculated.It can be seen from computing results that the stress and deformation of the two shoulders are bigger.When the collision happens,it will have obvious vibration.To reduce the size of the area which border upon the ... |
