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 A critical issue in the study of bird bumping is the establishment of a bird strike load mechanics model.A full-scale bird strike test is performed on the windshield of the aircraft. Based on the analysis of the experimental results of high-speed photography and dynamic strain measurement during the impact of the bird strike on the windshield, It is proposed that the bird strike load in oblique impact process can be simplified as a simplified analysis model of triangular pulse, and the finite element analysis of windshield bird strike using the simplified load model is carried out. The result is in good agreement with the test result
