摘要
采用有限元法对固体火箭发动机药柱在固化降温过程中的三维瞬态应力场进行了数值模拟,并分析了由温度变化引起的应力应变响应,得出了药柱危险点的位置,计算结果符合工程实际。
Using finite element method （FEM）, this paper carried out numerical simulation to three dimensional stress field in the process of solidifying propellant, in which the temperature of propellant was droping. The propellant＇s stress and strain caused by temperature change were also analyzed. The place of grain＇s dangerous point was obtained. The conclusion is in accordance with the engineering practice.
