　　以雙曲殼結(jié)構(gòu)復(fù)合材料為研究對(duì)象,利用Block-Lanczos研究分析法對(duì)復(fù)合材料層合雙曲殼結(jié)構(gòu)在溫度場(chǎng)下熱屈曲行為進(jìn)行研究,并研究了復(fù)合材料層合雙曲殼鋪層厚度、邊界條件、纖維方向等對(duì)臨界屈曲溫度的影響。結(jié)果表明:在均勻溫度場(chǎng)下復(fù)合材料層合雙曲殼臨界屈曲溫度與邊界條件、鋪層厚度、纖維方向有密切關(guān)系并成一定規(guī)律分布。通過(guò)對(duì)復(fù)合材料雙曲殼結(jié)構(gòu)的熱屈曲性能分析,為復(fù)合材料結(jié)構(gòu)設(shè)計(jì)和實(shí)際工程應(yīng)用提供了一種有效的分析及建模方法。
