The bird-strike is the main reason that could lead to the severe damages to the aircraft and the cost. In addition, aviation certification authorities have to prove the integrity of bird strike. The verification method for bird-strike is not by the test to evaluate at the early design phase but, by the analytical method. In this paper, birds were idealized as fluid to evaluate the analytical assessment and the SPH method and effect analysis research were applied using commercial analyzing instrument, Abaqus. The SPH method has an advantage of reducing element deformation and analyzing time much more than the previous ALE or Lagrangian methods. In order to verify the bird-strike analysis, the structures with rigid body structures having infinite stiffness were analyzed and the effectiveness of bird-strike applied the SPH method confirmed by comparison of the analysis value with experiment value. In addition, as for the airworthiness requirements on modified aircraft, the maximum speed of aircraft was 8000 lbs., assuming the flight path was the same as birds, and conducted analysis of the bird-strike on the radome and the structure supporting the radome based on the additional installation of satellite antenna on the existing aircraft in order to verify the design ensuring the continuous safe flight and landing of the aircraft once striking with 4 lbs. of birds, as a result, it was confirmed that the structural stability of antenna structures and radome after modification was secured based on the analysis result of SPH method on the bird-strike. This analysis on the bird-strike can present the optimum design for the radome prior to the mock-up test and it allows to reduce the cost and time of the development.

鸟击是可能导致飞机严重损坏和成本损失的主要原因。此外，航空认证机构必须证明鸟击的完整性。鸟击的验证方法不是通过在早期设计阶段进行评估的测试，而是通过分析方法来进行的。在本文中，将鸟类理想化为液体以评估分析评估，并使用商业分析仪器Abaqus进行SPH方法和效果分析研究。与以前的ALE或Lagrangian方法相比，SPH方法具有减少元素变形和分析时间的优势。为了验证鸟击分析，分析了具有无限刚度的刚体结构的结构，并通过将分析值与实验值进行比较，证明了SPH方法对鸟击的有效性。此外，对于改装飞机的适航性要求，假设飞行路径与鸟类相同，飞机的最高速度为8000 lbs。，并根据天线罩和支撑天线罩的结构对鸟类撞击进行了分析在现有飞机上额外安装卫星天线的目的是为了验证设计，以确保一旦以4磅的重击力就可以连续安全飞行和降落飞机。结果是，基于SPH方法对鸟击的分析结果，可以确定天线结构和天线罩在改装后的结构稳定性。这种对鸟击的分析可以在进行模型测试之前为天线罩提供最佳设计，并且可以减少开发成本和时间。
