摘　　要： 为了了解碎片云撞击密封舱穿孔对其内压力和温度的影响程度及规律,以平面激波和热力学理论为基础,建立了碎片云高速撞击密封舱穿孔对其内大气压力和温度影响的模型,通过计算发现模型计算结果与实验吻合得较好。通过模型计算,结果表明:碎片云撞击密封舱舱壁穿孔造成其内大气压力和温度的变化趋势具有相似性;舱壁穿孔瞬间,舱内大气压力和温度只在距穿孔处一定距离发生剧变;碎片云撞击速度越大,引起舱内大气压力和温度的变化也越大。 In order to know the influence extent and change ride of module interior atmosphere pressure and temperature created by debris cloud impact module wall. Based on the theory of plane shock wave and thermodynamic, the model that studies the effect of debris cloud hypervelocity impact perforation on pressurized module interior atmosphere pressure and temperature was built. The results obtained by using the model were consistent with experimental results. The calculation results show that the change tendency of module interior atmosphere pressure and temperature has similarity ; module interior atmosphere pressure and temperature generate great change in only certain range from perforation location in perforation instant; the larger the impact velocity of debris cloud, the larger the changes of module interior atmosphere pressure and temperature.
