摘要

摘要: 提出了含液金属蜂窝夹芯结构的防护方案；设计了含液金属蜂窝夹芯结构的制备方法，以满足结构内液体的密封、液体含量以及填充位置可调控的需求；并通过冲击实验获得了结构在不同冲击速度下的动态响应，同时采用有限元方法进一步讨论了冲击速度、液体含量对结构抗冲击以及冲后振动特性的影响。研究结果表明含液结构的抗冲击表现优于无填充结构，且含液结构抗冲击、冲后振动特性受含液量的影响，当芯体内充满液体时结构可获得最优的抗冲击性能。

Abstract: Based on the background of the further requirements for lightweight, explosion and impact resistance, and vibration reduction and noise reduction in the development of honeycomb structure in engineering science, a liquid metal honeycomb sandwich structure was proposed, and the preparation, impact experiments, and numerical simulation research of the liquid metal honeycomb sandwich structure were carried out. A preparation method for the liquid-filled metallic honeycomb sandwich structure was developed to meet the requirements of effective sealing of the internal liquid, adjustable liquid filling content, and controllable filling position within the structure. The first level light gas gun was used to launch foam bullets to simulate the explosion shock wave load, and the dynamic response of the structure under different impact velocities was obtained. At the same time, the commercial finite element software Abaqus/Explicit was used to carry out numerical simulation of the impact response of foam bullets in the metal honeycomb sandwich structure using the smooth particle hydrodynamics method, and the impact speed of foam bullets, the liquid content in the cell on the impact resistance and post-impact vibration characteristics of the structure were discussed further. The results indicate that the liquid-filled structure exhibits superior impact resistance and post-impact vibration performance compared with the unfilled structure. Moreover, with an increase in the liquid content, the displacement response of the liquid-filled structure shows a monotonic decrease, while the damping ratio demonstrates an increasing trend. When the core is fully filled with liquid, the structure achieves optimal impact resistance performance, with a decrease in peak displacement of approximately 13.66% compared to the unfilled structure, and an increase in damping ratio by approximately 1.6 times. The aforementioned research establishes the foundation for the extensive application of liquid-filled metallic honeycomb composite structures in the field of impact protection.
