| 摘 要： | 在给定热环境及动态随机载荷条件下,对某航天飞行器大面积热防护系统进行了力热耦合及随机振动分析,得出在该条件下的块间开缝位移.随后建立缝隙内的热传导模型,并依据开缝位移值,分析了它对大面积背温的影响.同时,还研究了在不同参数对防热有效性的影响规律.

| Abstract: | Under the certain thermal and dynamical random loads,the thermo-mechanical coupled analysis and random vibration response analysis were carried out on the thermal protection system of some spacecraft.The computation result represented the gap displacements between the block components.Based on the gap displacement,together with the gap heating model,the thermal protection validity of the thermal protection system was investigated.Meanwhile,the effects of different factors on the validity were analyzed. |
