Factors Study Influencing on Numerical Simulation of Aircraft Windshield against Bird Strike

Abstract: The combined model of UniGraphics(UG) and ANSYS-LS-DYNA software and finite element (FE) model of aircraft windshield and windshield structure for bird strike were built. The windshield structure is composed of windshield, framework, arc-frame and gasket. The factors influencing on dynamic response for bird strike were analyzed such as bird velocity, mesh density of windshield, mesh density of bird, boundary condition, material model of windshield, analytic methods and components of windshield structure. The r… Show more

“…Although we considered a reverse phenomenon, when the bird hits an immobile windshield, such an approach is often described in literature. The obtained findings come very close to those presented in the papers dealing with this issue, including [3,5]. The suggested multimaterial dummy bird model, with a simplified shape, seems to be sufficient for this type of analyses.…”

“…The material available under various trademarks such as Plexiglas™, Perspex™, is mostly composed of polymethyl methacrylate -PMMA. The material parameters of this type of glass, mentioned in paper [5], have been listed in Table 1. We used the elastic-perfectly-plastic model (*MAT_PLASTIC_KINEMATIC) [1], with the modulus of reinforcement equalling 0.…”
