本研究重点研究碳纤维包裹复合材料圆柱体在受到平端、半球形和圆锥形冲击器冲击时的冲击行为。分析了气缸的损伤形貌和损伤机理。得到了不同冲击器和冲击能量冲击后气缸最大冲击力、冲击过程持续时间和吸收能量的变化规律。开发了有限元模型，模拟结果与测试结果基本一致。最后以平头冲击器为例，讨论了圆柱体在加压和冲击作用下的应力分布。
This study focused on the impact behavior of carbon-fiber-wrapped composite cylinders subjected to impact from flat-ended, hemispherical-nosed and conical-nosed impactors. Damage morphologies of the cylinders and mechanisms of the damage were analyzed. Change laws of the maximum impact forces, durations of impact processes and energies absorbed by the cylinders after impact with different impactors and impact energies were obtained. A finite element model was developed and the simulation results were in reasonable agreement with the tests. Finally, taking the flat-ended impactor as an example, stress distributions of the cylinders under pressurization and impact were discussed.
