摘要
因鸟撞问题引起的飞机结构破损等损失问题需要解决,采用对比分析的方法,对目前鸟撞风挡问题的地面试验法、工程计算法及有限元仿真法进行详细介绍,比较不同方法的适用条件、范围及其优劣。选取某飞机风挡层合玻璃作为研究对象,采用有限元仿真法,建立风挡鸟撞模型,利用任意拉格朗日欧拉耦合法(ALE)完成相关分析,结果得到鸟撞风挡的变形及其速度、加速度等参数,并总结鸟撞风挡问题的三种分析方法的优劣性,为飞机风挡设计提供参考。
To avoid the disasters caused by the bird strike problem,the method of comparative analysis is adopted.The ground test,engineering calculation and finite element simulation of the current method for bird strike are introduced in detail.A certain aircraft windshield laminated glass is selected as the research object,the bird strike windshield model by FEM is established,using the arbitrary Lagrange-Euler coupling(ALE)method for the simulation.Then the windshield’s displacement,velocity,acceleration and other parameters are obtained.In the end,advantages and disadvantages of the three methods for bird strike is analyzed.The analysis results can be provided as reference for windshield design.
