摘　　要：嵌入式共固化复合材料阻尼结构是一种新型阻尼处理结构,在航空、航天、高速列车等高科技领域有广阔的应用前景。采用LS-DYNA显式动力学软件建立了该结构的有限元分析模型,对这种新型阻尼结构的低速冲击性能进行数值模拟,并将数值模拟结果与实验数据进行比较以说明模拟方法的有效性。结果表明这种新型复合材料阻尼结构的抗冲击性能大大优于相同材质的复合材料结构。Embedded and co-cured composite damping structure is a new damping processed structure, which could be widely used in high-tech fields such as aviation, aerospace, high-speed train, etc. The explicit dynamic analysis software LS-DYNA was used to simulate the low velocity impact on embedded and co-cured composite damping structure panels. The simulation results were compared with the experimental data to illustrate the validity of modeling and calculation method. The results of simulation show that the impact resistance of embedded and co-cured composite damping structure is much higher than that of composite structures without viscoelastic damping material.
