摘要
文章以航天器三层防护结构为研究对象,通过数值仿真的方法,对球形铝弹丸高速撞击三层铝板防护结构的损伤特性进行了研究;通过与实验结果的比较验证了仿真模型的有效性,并针对防护板间距与厚度对铝板损伤特性的影响进行了数值模拟仿真分析。结果表明,第二层防护屏位于防护结构中间时,舱壁所受损伤最小,且增加第二层防护屏的厚度能有效减小舱壁受到的损伤。
In this paper,the damage characteristics of the three-layer protective structure of spacecraft are studied by numerical simulation method.The effectiveness of the simulation model is verified by comparing with the experimental results.The numerical simulation analysis of the influence of the spacing and thickness of the protective plate on the damage characteristics of the aluminum plate is carried out.The results show that when the second layer of protective screen is located in the middle of the protective structure,the damage to the bulkhead is the least.Increasing the thickness of the second protective screen can effectively reduce the damage to the bulkhead.
