| Abstract: | In this paper, the temperature respond and stress respond of the solid propellant motor to the alternating environmental temperature were found by finite element method on the basis of the environmental temperature model, heat transfer model and viscoelastic constitutive relation. The temperature profiles, stress profiles, and the conclusions about the dangerous position of the motor and the dangerous season were given. |
