Abstract
Aiming at the problem of the solid rocket motor affected by the temperature load in the service process , the effect of temperature changing on a motor ’ s grain is researched .With the Abaqus software , the simulation model and math model of the motor ’ s finocyl grain are built .Using finite element method, the temperature , stress and strain of the finocyl grain under conditions of different temperature load are analyzed , and the loading response is studied .The results indicate that , the temperature distri-bution is uneven under the condition of temperature changing , and there is temperature gradient in the fin-ocyl grain .The stress and the strain of the finocyl grain decreases with the temperature increasing and in-creases with the temperature falling under zero stress temperature .关键词
