摘要
Abstract
To meet the needs of air defense weapon testing and the army air defense training ,a new kind of umbrella-type deployable air target was designed based on the concept of deployable structure .The structure scheme was put forward using conceptual design method .Sleeves and braces were used to realize the axial and radial directions respectively and was driven by springs . The target stayed in collapsed state before target-supplying ;when the target was released in the air ,it could automatically unlock ,deploy to designed position and lock again to begin target-sup-plying .The simulation of the deployment process was analyzed to prove the feasibility of the scheme .Free modal analysis of the deployed structure was carried out with finite element method and the first 7 order modes were analyzed .A reduced-scale model was made and the automatic de-ploy experiment in the air was carried out .The research results show that the structure can de-ploy rapidly and successfully in 2.8 s ;the structure can automatically unlock and the linkage work well to deploy in two directions successively with only one unlocking operation .The work of model making also provides experience for the further study .关键词
