@@@@To estimate the effects of oceanic environment temperature on the cumulative damage of shipborne missile solid rocket engine, and to ensure the reliability of the engine , the observed temperature data of shipborne environment and temperature model data on skewed distribution are taken as boundary condition to solve the temperature and stress response of the shipborne missile solid rocket engine to oce -anic environment using the finite element method , the temperature and stress distribution of engine are ob-tained.The results show that the effects of temperature model and observed data on temperature and stress of the engine grain are very near,and can be applied to research the response of the solid rocket engine grain to the temperature load.
