摘要
星箭适配器(PAF)隔振技术是指在不修改卫星原有结构的前提下,设计具有隔振效能的适配器或在适配器与星箭界面之间引入隔振装置,以隔离卫星发射阶段轴向或侧向的振动。该技术可以降低卫星的质量控制成本,提高卫星发射的可靠性。文章对星箭适配器隔振技术国内外研究进展进行了总结和评述,对美国CSA和欧空局EADS的产品做了介绍,并对我国星箭适配器隔振技术的未来发展途径提出了建议。
The vibration isolation technique of payload attach fitting(PAF) refers to inserting isolators or the isolating PAF between the satellite and the launch vehicle to isolate the satellite axial/lateral vibration without any alterations of the existing satellite structure. The use of this vibration isolation technique can reduce the launch-induced dynamic loads and the quality control costs of the satellite, and to improve the satellite reliability during launch. In this paper, the recent development of the researches and engineering applications of the vibration isolation technique of PAF are introduced in detail and some suggestions about future development of this vibration isolation technique in China are proposed.
