星箭適配器（PAF）隔振技術(shù)的進(jìn)展

The Recent Development of Vibration Isolation Technique of Payload Attach Fitting

摘要: 星箭適配器（PAF）隔振技術(shù)是指在不修改衛(wèi)星原有結(jié)構(gòu)的前提下，設(shè)計具有隔振效能的適配器或在適配器與星箭界面之間引入隔振裝置，以隔離衛(wèi)星發(fā)射階段軸向或側(cè)向的振動。該技術(shù)可以降低衛(wèi)星的質(zhì)量控制成本，提高衛(wèi)星發(fā)射的可靠性。文章對星箭適配器隔振技術(shù)國內(nèi)外研究進(jìn)展進(jìn)行了總結(jié)和評述，對美國CSA和歐空局EADS的產(chǎn)品做了介紹，并對我國星箭適配器隔振技術(shù)的未來發(fā)展途徑提出了建議。

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.
