Abstract

The material properties play an important part in evaluating the structure integrity of the solid rocket motor gain. Based on the structure integrity analysis of perfect solid rocket motor grain, the computational models are established to assess the effects of material parameters on it. Under the internal pressure, four test groups are performed. Each test group only had one variable, while the values of other variables were fixed. Through changing the value of the variable, the relationship between the Von Mises strain of dangerous point and variables are studied. The results show that the main factors are the initial elastic modulus and the poisson's ratio of propellant.
