摘要

建立了鸟撞复合材料雷达罩有限元模型，用壳单元模拟雷达罩，在鸟体周围附加用于模拟空气的欧拉流动域，利用显示动力分析软件LS-DYNA对鸟撞复合材料雷达罩的过程进行了数值模拟，对雷达罩的破坏响应进行了分析。结果表明，在撞击的过程中，应力的峰值主要出现在被撞击区域的周围；部分区域的不同材料层间会承受不同的应变趋势。

Abstract

The finite element model of radome made of composite material for the purpose of simulating Bird Strike was set up . Using the shell element to simulate radome, simultaneously attaching the ALE elements of the air aroungd the bird, simulated the process of the bird strikes composite radome making use of display dynamic analysis software LS-DYNA and analyzed the damage response of the radome . The results show that the impact of the process, the peak stress mainly distributes in the region of impact surrounding; part of the region between layers of different materials will withstand different strain response form .
