摘要: 針對(duì)電動(dòng)振動(dòng)臺(tái)進(jìn)行整星水平振動(dòng)試驗(yàn)時(shí)垂直方向響應(yīng)過(guò)大這一普遍存在的問(wèn)題，文章提出了通過(guò)設(shè)計(jì)具有加強(qiáng)筋的加強(qiáng)臺(tái)面提高滑臺(tái)抗彎模量,抑制響應(yīng)。通過(guò)有限元方法分析了安裝加強(qiáng)臺(tái)面后對(duì)水平滑臺(tái)、水平滑臺(tái)與振動(dòng)花盆組成的振動(dòng)工裝系統(tǒng)、考慮衛(wèi)星質(zhì)量影響的振動(dòng)工裝系統(tǒng)等三種工況下模態(tài)振型的變化，說(shuō)明抗彎模量有明顯提高。Abstract: It is proposed that a reinforced panel should be used to increase the bending rigidity of the slip table and to reduce the vertical response of the table in the horizontal direction vibration test of spacecraft. In addition, the modal analysis is made using FEA method in three working states: fixing the reinforced panel upon the slip table, the slip table and vibration fixture as a vibrating system, and considering the mass of satellite.
