1 前言伴随人类在航天领域的活动不断拓宽以及航天应用的日趋多样化,要求从人造卫星、轨道服务飞行器到空间平台、空间站等空间基础设施都必须是多功能、高性能化的系统。这些空间基础设施,比如由美国牵头,有美、俄、欧空局(ESA)、日本、加拿大等国家和国际空间组织参加研制、正在轨组装的阿尔法国际空间站自不待言,就是宇宙开发事业团(NASDA)研制和计划发射的对地静止轨道三轴控制卫星的形状也要比以往的卫星火得多、结构也复杂得多。而要研制和发射这些大型空间结构有许多必须解决的技术课题。这些大型空间基础设施有许多大型挠性结构,它们的轻型化就是一个要解决的重要
1 Introduction With the continuous widening of mankind’s activities in the field of spaceflight and the ever-increasing variety of aerospace applications, the space infrastructure from satellites, orbital service space vehicles to space platforms and space stations must be multi-functional and high-performance systems. These spatial infrastructures, such as the Alpha Space Station under the lead of the United States, the United States, Russia, the European Space Agency (ESA), Japan, Canada and other countries and the International Space Organization, goes without saying that the Space Development Corps (NASDA) and planned launch of the geostationary orbit three-axis control of the shape of the satellite also much more than the previous satellite fire, the structure is also much more complex. There are many technical issues that must be solved to develop and launch these large-scale space structures. There are many large, flexible structures in these large space infrastructures, and their weight reduction is an important issue to be solved
