摘要

摘要: 研究鸟撞问题时,一个很关键的问题是鸟撞载荷力学模型的建立.对飞机风挡进行全尺寸鸟撞试验,通过对鸟弹撞击风挡玻璃过程高速摄影、动态应变测量等试验结果的分析,提出了斜撞击过程的鸟撞载荷可以简化为三角形脉冲的简化分析模型,利用该简化载荷模型对风挡玻璃鸟撞进行的有限元分析,结果和试验结果很好地相符.

Abstract: To study the bird impact problem, one key point is to establish the bird impact loading model. This paper, based on the full scale bird impact tests, and detailed analysis the results of high-speed photography, dynamic strain gauge, puts forward that triangle pulse simply model could be simplified by bird impact loading of inclined impact process .The analysis results that calculate the simply model using finite element analysis tools are accordance with the results from full-scale bird impact tests.
