| 摘 要： | 采用非线性有限元法,基于ABAQUS/Explicit软件平台及内嵌的材料用户定义子程序(VUMAT),建立了鸟撞飞机风挡的力学分析模型.比较了有限元模型中玻璃骨架、弧框和橡胶垫片对风挡动响应分析结果的影响,并与全尺寸风挡鸟撞试验数据进行了对比.对比结果表明,考虑了玻璃骨架、弧框和橡胶垫片的有限元模型所计算得到的位移、应变曲线与试验实测曲线的一致性有了改善.最后,探讨了玻璃骨架、橡胶垫片的厚度和弹性模量对风挡抗鸟撞能力的影响规律,为风挡的抗鸟撞设计及改型提供参考.

| Abstract: | A finite element model(FEM) of bird impact on the windshield is established via the nonlinear finite element method,combined with the user-defined materials subroutine(VUMAT) of the ABAQUS/Explicit software.The dynamic response of bird strike on aircraft windshield is analyzed in two different configurations,with and without the surrounding structure frame,skin and rubber layer.By comparing the simulation results and the full-scale experiment data,the results of FEM with the surrounding structure have a bet... |
