Abstract: 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.
