摘要
宇航空间中的微低重力环境使得所处其中的航天器和宇航员表现出与在地面重力环境下不同的受力状态和动态性能,因此需要在地面对这种微低重力环境进行模拟。综述了目前常用的几种微低重力模拟方法,其中悬吊法因为模拟时间长、模拟范围大、不引入附加惯量的优势被广泛采用。从微低重力模拟原理角度对现有的悬吊式微低重力模拟系统研究成果进行了分类和国内外研究现状的综述。根据微低重力模拟的需求归纳了悬吊式微低重力模拟系统的2条设计准则和3个关键技术,详细综述了这3个关键技术的研究现状。探讨了未来悬吊式微低重力模拟系统设计方面和3个关键技术方面的发展趋势。
The micro-low gravity environment in aerospace causes different forced states and dynamic performance of the spacecraft and astronauts from those in the ground gravity environment;therefore,it is necessary to simulate this environment on the ground.Several commonly used micro-low gravity simulation methods are reviewed.Among them,the suspension method is widely used because of its advantages of long simulation time,large simulation range,and having no additional inertia.From the perspective of the system scheme principle,the research results of existing suspended micro-low gravity simulation systems at home and abroad are classified and reviewed.According to the requirements of micro-low gravity simulation,two design criteria and three key technologies of the suspension micro-low gravity simulation system are summarized.The research status of these three key technologies is reviewed in detail.The development trends of the system design and three key technologies of the future suspended micro-low gravity simulation are discussed.
