| Abstract: | The basic theory of dynamic elastic mechanics and SPH(Smothed Particle Hydrodynamics) bird model were introduced. Combining the mechanical parameters of related material and basing on the explicit finite element software PAM-CRASH,the analysis and validation of bird-strike resistance for the top nose skin of a large commercial aircraft was carried out. In addition, two types of metal-glass fiber were used as the alternative material of the top nose skin. Without mass changing the material's ply stacking sequence optimization was conducted by comparing the capability of energy absorbing. The optimizing conclusion can be used as the reference for the structural design. |
