文章介绍了国内外微小空间碎片超高速撞击地面模拟实验研究的现状,描述了国内等离子体微小空间碎片加速器的研制进展和初步实验结果,分析了该加速器在空间碎片防护研究工作中的应用。在初步调试阶段,在系统设计满负荷储能6%和35%的条件下,分别将100μm和200μm的玻璃微粒加速至5.5km/s和9.3km/s。利用该加速器可以模拟研究10～1000μm的微小空间碎片对卫星功能材料的撞击损伤特性,可以加速模拟研究卫星关键部件或分系统在大量微小空间碎片撞击下的失效机理和失效模式,为卫星防护微小空间碎片的设计提供技术支持。该加速器还能为国内发展星载空间微小碎片探测仪器的设计和标定提供模拟实验条件。
This paper introduces the status quo of simulation experiments of the ultra-high-speed impact micro-space debris at home and abroad, describes the development and preliminary experimental results of the domestic plasma micro-space debris accelerator, and analyzes the application of the accelerator in the research work of space debris protection. During the initial commissioning phase, the glass particles of 100μm and 200μm were accelerated to 5.5km / s and 9.3km / s under the conditions of 6% and 35% of the designed capacity of the system. The accelerator can be used to simulate the impact damage characteristics of tiny space debris with the size of 10 ~ 1000μm on satellite functional materials, and to accelerate the simulation of the failure mechanism and failure mode of key satellite components or subsystems under a large number of tiny space debris impacts. Space debris design to provide technical support. The accelerator also provides simulated experimental conditions for the design and calibration of micro-debris detection instruments developed in China.
