Investigation of the Bird Shape Effects on the Simulation Results of Bird Striking Laminated Aircraft Windshields

Abstract:

Finite element simulations are widely used in the analysis of bird strike events in the literatures. While the shapes of the artificial birds used in the simulations are not indentical. In order to investigate the effects of artificial bird shapes on the response of laminated aircraft windshield, the often used shapes including hemispherical-ended cylinder, straight-ended cylinder and ellipsoid are modeled in this work. The striking velocity is 80.6 m/s and the SPH method is adopted. Based on the calculation results, the impact force, dissipated energy and major principle stress in the glass are analyzed. The analysis shows that the initial contact area would affect the values of these results. The shapes and aspect ratios affect the results through the initial contact area.
