【 摘 要 】

In order to determine the effect of charge density on the internal temperature and stress in the propellant, based on the Visco-Scram model and the JWL equation of state, the influence of different charge densities on the internal temperature and stress distribution of the charge is analyzed by using the finite volume method. The result indicates that the maximum charge temperature decreases with the increase of charge density, the maximum value of stress increases with the increase of charge density, but the change of the charges are not significant, which shows that the influence of the charge density on the temperature and stress has a less impact, which provides a reference for the influence of the charge density on the launch safety.
