碳纤维复合材料具有优异的力学性能，被广泛应用于航空航天等领域，但在飞行中容易受到鸟类的撞击而损坏，因此，研究鸟体撞击复合材料层合板的过程具有重大的意义。以碳纤维复合材料层合板为研究对象，基于光滑粒子流体动力学法（SPH）和Ls-Dyna prepost显示动力学对其受到鸟体撞击的过程进行分析和研究。首先，采用拉格朗日模型建立碳纤维复合材料层合板的有限元模型，采用SPH方法建立鸟体模型。其次，考虑不同速度、不同姿态角对鸟体与层合板撞击时接触力及层合板能量耗散情况的影响规律。最后，分析在不同铺层角度条件下层合板对鸟撞吸能效果的影响。结果表明：接触力峰值随着鸟体冲击速度的增加而增加。鸟体姿态角在60°时层合板吸收更多的动能。铺层角度为［0/90/0/90/0/90/0/90］的层合板抗冲击能力最好，合理设置铺层角度能够提高复合材料层合板的吸能效果。

Carbon fiber composites have excellent mechanical properties and are widely used in aerospace and other fields, but they are easily damaged by the impact of birds in flight, so it is of great significance to study the process of bird body impact composite laminates. In this study, the process of the impact of the carbon fiber composite laminate on the bird body was analyzed and studied based on the smooth particle hydrodynamics (SPH) method and the Ls-Dyna prepost display dynamics. Firstly, the Lagrangian model was used to establish the finite element model of carbon fiber composite laminates, and the SPH method was used to establish the bird body model. Secondly, the influence of different velocities and different attitude angles on the contact force and the energy dissipation of the laminate during the collision between the bird body and the laminate were considered. Finally, the influence of laminate on the energy absorption effect of bird strikes under different ply angles was analyzed. The results show that the peak contact force increases with the increase of the impact velocity. At a bird attitude angle of 60°, the laminate absorbs more kinetic energy. The laminate with a ply angle of [0/90/0/90/0/0/90/0/90] has the best impact resistance, and a reasonable ply angle can improve the energy absorption effect of the composite laminate.
