| 摘 要： | 分析飞鸟与航空发动机叶片的撞击损伤时，需要准确预估叶片的瞬态响应。其中叶片的变形会影响到撞击载荷的大小与分布，从而影响到叶片的响应。本文提出一种简单有效的计算方法，考虑了上述耦合效应，并以模型叶片为例，分析了它对叶片响应的影响程度，为工程实际应用积累了经验。

| Abstract: | It is necessery to calculate the transient responses of blades precisely in analysis of blade damage due to bird impact.Because the deformations of blade can influence the distribution and magnitudes of bird impact loads,the coupling of the bird impact with blade deformation has a remarkable influence on the transient responses of the blade.A simple and effective method is provided to analyze the responses of blades with consideration of this coupling.Taking a model blade as an example,its influence extent is also sized up. |
