摘要
空间环境是多因素交叉耦合作用的复杂、动态系统,是影响空间装备正常服役的重要因素,深入开展空间特殊环境效应研究已成为世界各国降低航天器在轨故障率、保证空间装备长期可靠运行的重要手段。总结近30年来世界各国进行空间环境效应研究的主要方法,即空间飞行试验、地基模拟试验和数值仿真计算,分析各种研究方法的优点与不足;综述各主要航天大国材料空间环境效应的研究现状,指出今后可以从基础理论和技术设备两方面对空间环境效应进行深入研究,通过开发新型的模拟试验设备和先进的数值仿真技术,未来将有望大大减少空间环境效应研究的周期和成本,从而加速推进相关空间材料和技术的研究与应用。
Spacing environment is a complex and dynamic system that cross-coupled by various factors.It has been considered as a critical factor which affects the service life of space equipment. Therefore, developing an in-depth study on space environment effect has become an important means to reduce on-orbit failure rate of the spacecraft and guarantee long-term reliable operation of the space equipment for countries around the world.The main approaches in studying space environment effect were reviewed around the world in the last three decades, including spaceflight test, ground simulation test and numerical simulation.Based on the analysis of the advantages and disadvantages of those approaches ,the research status in space environment effect of major spacefaring nations was summarized.It was pointed out that space environment effect can be further studied from the perspectives of the basic theory and the technical equipment in the future.It was expected that the cycle and cost of the study on space environment effect will be largely reduced by developing new simulation test equipment and advanced numerical simulation technology, and therefore the research and application of the related space materials and technology will be accelerated.
