实验室聚能高速碎片生成装置设计与研究

地面超高速模拟实验是研究微小空间碎片撞击效应最经济和最有效的手段。目前的空间碎片生成装置安全性较低，无法在实验室内使用。为了在实验室模拟空间超高速碎片，研究设计了带防护壳体的占据式聚能装药空间碎片生成装置。根据数值模拟结果，加工制作了实验装置，通过试验测得截取的射流头部速度为10．52km／s、10．62km／s，与利用AUTODYN软件模拟得到的射流头部速度11．385km／8基本吻合。装置的保护外壳较为完整，实现了在实验室中模拟空间超高速碎片。

Design and Research of Laboratory Hypervelocity Debris Launcher Based on Shaped Charge

Ground hypervelocity simulation experiment is the most economical and effective means for studying the space micro-debris impact effect. The existent space debris launcher is not safe enough to use in the laboratory. This paper researched and designed a conical shaped charge with an inhibitor, which was equipped with a protecting shell and thus en- ables to apply in the laboratory, to simulate the hypervelocity space debris. According to the simulation results, an experi- mental device was installed to measure the speed of the tip. The results show that the speeds of the tip are 10.52 km/s and 10.62 km/s, which are consistent to that of 11. 385 km/s simulated by the AUTODYN software. The protecting shell of the device is relatively integrated, which realizes simulating the hypervelocity space debris in the laboratory.
