为给空空导弹与发射装置的振动防护设计提供振动响应数据，本文选取GJB150规定的组合式外挂系统振动条件，对某型发射装置与空空导弹进行随机振动响应测试。采用前、后挂点两点平均值激励控制，得到发射装置6个测试点、导弹12个测试点的功率谱密度和均方根加速度响应值。试验结果表明：（1）发射装置与空空导弹每个位置上的振动响应随激励载荷的增大而增大。（2）发射装置靠近前后挂点的响应放大较小，前端后端放大较大，呈现双悬臂梁特征。（3）导弹除了2个测试点之外均小于激励载荷，呈现吸收能量的细长柔软弹性体特征，增大的测试点为弹体的振动模态响应结果。
為給空空導彈與髮射裝置的振動防護設計提供振動響應數據，本文選取GJB150規定的組閤式外掛繫統振動條件，對某型髮射裝置與空空導彈進行隨機振動響應測試。採用前、後掛點兩點平均值激勵控製，得到髮射裝置6箇測試點、導彈12箇測試點的功率譜密度和均方根加速度響應值。試驗結果錶明：（1）髮射裝置與空空導彈每箇位置上的振動響應隨激勵載荷的增大而增大。（2）髮射裝置靠近前後掛點的響應放大較小，前耑後耑放大較大，呈現雙懸臂樑特徵。（3）導彈除瞭2箇測試點之外均小于激勵載荷，呈現吸收能量的細長柔軟彈性體特徵，增大的測試點為彈體的振動模態響應結果。

In order to obtain vibration response data for air-to-air missile and launcher system design of anti-vibration, a random vibration response test on air-to-air missile and launcher system is implemented. A combined external stores random vibration condition of GJB150 standard is applied in the experimental test.By using the fore and hind support points mean value excitation, power spectrum density ( PSD) and root mean square ( RMS) acceleration of 6 test points on launcher and 12 test points on air-to-air missile are acquired.The experimental results show that:(1) Every test point vibration response on launcher and air-to-air missile increases with the increase of excitation load.(2) The response of launcher near fore and hind support points has a smaller amplification, and the amplification for front-end and back-end is larger, so that the launcher shows characteristic of double cantilever.(3) Except two test points, the others are less than excited load, showing the energy absorption characteristic of the slender and pliable elastic struc-ture, and the increasing test points are the result of vibration mode in response to the elastomer.
