Abstract:In order to design the rear observation window glass on aircraft cockpit under bird impacting, the experiment of bird impact on rear observation window was carried out. In experiment the time histories for strain on two points were measured. A full-scale finite element model of bird impacting on rear observation window was established to simulate the experimental process by using large-scale commercial impacting analysis software PAM-CRASH. The strain results of simulation and test were compared, the good agreement between simulation and test indicated that the numerical model established in this paper was rational. Then the dynamic response of rear observation window structure impacted by bird was studied in which the observation window has different thickness of inside and outside glass layer as well as middle air layer. Some influence tendency was obtained which can provide technical guidance for the design of rear observation window glass impacted by bird.
