Simulation on Collision of Bird with Windshield by Using MCA

The collision process of a flying bird and the aircraft windshield was simulated by using movable cellular automata （MCA） method to improve the structure design of aircrafts. The simulation results show that the whole strike process is performed in 4. 8 ms, the critical strike velocity for an aeronautic glass windshield is 360 km/h, the windshield vibrates and deforms in the collision, and after absorbing the kinetic energy, its temperature increases. The simulation results coincide with the experiment data better. It is clear that MCA method has more advantages than the usual methods of continuum mechanics.
