Parameter Study of Wing-Type Structure Subjected to Impact Loading

This research scopes to the modelling and simulating of one section of wing-type structure subjected to a bird strike. Modelling and simulations are performed through finite element (FE) approach by using ANSYS Workbench (Explicit Dynamic). The bird is modelled as a rigid body, having a similar weight to an actual bird. Varying desired parameters of the leading edge—curvature radius (R), skin thickness (T), and number of ribs (N) behind the leading edge—provides a better understanding of the extent of each design modification. Six different values of R and T are studied, with none (N0), one (N1), and two ribs (N2) behind the leading edge’s skin considered. By impacting the model with 120 m/s of initial velocity, the effect of T is seen to exhibit linear relationship with energy absorbed (EA) and specific energy absorbed (SEA). For R, a peak EA and SEA has been identified. Adding ribs behind the leading edge’s skin was also proven to provide more strength. Spacing of ribs is expected to vary the performance. The effect of impact location has been analysed as well.
