摘要/Abstract

摘要： 携带探测仪器的穿透器高速侵彻行星体，内部科学仪器将受到高g值冲击，极易损坏.为了科学仪器的缓冲防护以提高自身存活率，本文设计了一种具有多层能量吸收结构的穿透器样机，将泡沫铝填充薄壁结构(简称FTS)应用于内部载荷的缓冲防护设计上以提高存活率.在LS-DYNA中模拟了穿透器侵彻星球介质的过程，通过冲击试验和仿真分析验证了该种措施的有效性.研究结果表明:FTS对隔离冲击和能量吸收效果明显，为穿透器工程样机的研发提供了重要的解决方案.

关键词: 穿透器, 泡沫铝填充薄壁结构, 缓冲防护, 冲击响应, 侵彻

Abstract: When a high-speed penetrator carrying detection equipment penetrates planetary bodies at high speed， the scientific instruments in it are impacted by high g value and easily damaged. The buffer protection structure for scientific instrumentation is essential for improving the survival rate. This work suggested a penetrator with a multi-layered energy absorbing structure where the foam-filled thin-wall structure (abbreviated as FTS) is applied to the penetrating vibration-damping structure to improve the survival rate of the penetrator. The penetrating process of the penetrator into the planetary medium is simulated in LS-DYNA. Then， the reliability of the penetrator’s finite element model was verified by the impulse response test and simulation. The results suggest that FTS has a beneficial effect on isolation impact and energy absorption and provides an important solution for the research and development of penetrator engineering prototype.

Key words: penetrator, aluminum foam-filled thin-wall structure, buffer protection, impact response, penetration
