英文摘要：

In order to validate the numerical model for simulating bird hitting against an organic glass plate, and also to provid valuable data for designing and manufacturing aviation organic glass windshield with higher anti-bird hitting performance, detailed experimental study concerned the complete dynamic response process of YB3 avaiation organic glass plate subjected to bird hitting with two different velocities was carried out by using a dynamic data acquisition system. The displacement- time profiles from three points and the strain-time profiles from seven points on a YB3 plate were measured, and four profiles of the support reaction force variation along hitting directions were slao measured. At the same time, whole process of dynamic deformation and damage of plate due to the bird hitting was recorded by high-speed camera system. The effectiveness of test results was analyzed, and the YB3 plate damage mode after breakdown by bird hitting was also analyzed. Good agreement between two repeat tests indicates that the results presented in this paper are valid and reliable.
