| 摘 要： | 建立了鸟撞蜂窝夹芯结构雷达罩的有限元分析模型。选取具有代表性的四类不同重量和大小的鸟及多种撞击速度，运用大型非线性动力学有限元程序ＭＳＣ／Ｄｙｔｒａｎ的ＡＬＥ计算功能，计算得出了六种可能情况下雷达罩抗鸟撞动力响应及结构受损情况。最后对结果进行了分析。数值模拟结果为雷达罩抗鸟撞设计提供了理论参考依据。

| Abstract: | In this paper,the FEM analysis model for bird impacting radome with composite sandwich structure is established.According to four types of birds with different weights and sizes,the dynamic responses and the conditions about structural damage are obtained by using the computation ability concerning ALE in nonlinear contact impact program MSC/Dytran.Six possible conditions are analyzed.The result of numerical simulation offers a theoretical reference for the engineering design of anti bird radome. |
