摘要

摘要: 鸟撞发动机风扇叶片对飞机的危害性极大.为了研究叶片受鸟撞的损伤，以某型发动机风扇叶片为基础，设计夹具将叶片紧固，进行两组鸟撞叶片试验得到叶片的损伤结果.试验后使用LSDYNA软件通过数值模拟方法对试验结果进行验证.以试验为基础建立鸟撞三边夹持叶片模型，研究四种影响叶片损伤结果的撞击工况对叶片损伤的影响.结果表明：试验工况对叶片损伤的影响根本上是鸟体传递给叶片能量的改变.随着传递能量的增大，叶片的损伤将由鼓包变为裂缝直至最后破损.通过研究叶片损伤发现在特定工况中鸟撞三边夹持叶片试验可以有效模拟部分鸟撞旋转叶片的试验.

Abstract: The damages caused by bird impacts on engine fan blades in aircraft is extremely serious. To study these damages to the blades, an experiment was conducted based on a certain type of engine fan blade clamped by fixtures on 3 sides. Then 2 groups of bird-blade impact tests were completed, and the results of blade damages were obtained. Simultaneously, the LS-DYNA software was used to numerically verify the experimental results. A 3-side-clamped blade model for bird impact was established based on the experiment to study the effects of 4 impact conditions on blade damages. The results indicate that, the effects of experimental conditions on blade damages are fundamentally due to the energy changes transmitted from the bird body to the blade. As the transmitted energy increases, the damage to the blade will change from a bulge to a crack until finally rupture. Through the study of the damages to the blade in specific impact conditions, the 3-side-clamped blade-bird impact test can effectively simulate a part of the tests on bird impacts on rotating blades.
