During the process of launching, the gun-launched rocket is always subjected to a very high overload, even more than 104g. Therefore, the stress and strain analysis of solid propellant grains is of great significance. In this paper, we used the finite element software to simulate the stress and strain of the grain structure during the launching process, conducting a comparative study on the effects of axial load, rotating load and grain-retaining plate friction on the maximum von Mises stress and maximum principal strain of the grain. The results showed that considering rotating load and the grain-retaining plate friction, the maximum von Mises stress and the maximum principal strain of whole grain will be significantly increased, and the grain-retaining plate friction will affect the distribution of maximum von Mises stress and the maximum principal strain.
