最后，采用ansys程序分析了合金材料、復(fù)合材料的板、彈體結(jié)構(gòu)的熱振動特性。在不同的熱載條件下，取得以下結(jié)論：升溫導(dǎo)致的材料機械性能下降都會降低結(jié)構(gòu)固有頻率，而溫度梯度產(chǎn)生的熱應(yīng)力可能降低也可能提高結(jié)構(gòu)的固有頻率；金屬材料結(jié)構(gòu)的固有頻率受溫度的影響要比復(fù)合材料結(jié)構(gòu)的固有頻率受溫度的影響要明顯。 - This article gives the subsistent ability and the analysis result of intensity after repair in the open field airplane composite material structure by research the intensity , rigid and repair problem under a axis compress loads on a typical three stiffened composite laminate which has a penetrability crack ( a scatter damage ) by a shrapnel
