| 摘 要： | 基于瞬态动力学软件PAM—CRASH,引入状态方程定义鸟体的本构模型,计算铝合金平板在鸟撞下的动态响应,计算结果与试验结果吻合较好,表明建立的数值模型合理可靠.采用数值模拟计算了两种结构形式以及相同结构形式不同隔板厚度的前缘结构在鸟撞下的动态响应,比较其吸能情况,并分析其规律,为后续前缘结构设计工作提供支持.

| Abstract: | Using the PAM-CRASH software for transient dynamics, a constitutive model of bird is established based on the equation of state. The calculated dynamic response agrees well with experimental results for the aluminum plate under the bird impact. Two different structure types and the same structure with different thicknesses are simulated to model the dynamic response under the bird impact for the leading edge structure. Then, the energy absorptions are compared and analyzed. The research result can be used for the design of leading edge structures. |
