| Abstract: | Based on three-dimension viscoelastic finite element method, by MSC/NASTRAN software system, the grain structural integrity of the motor under internal pressure load, under thermal load and under the combined action of the two load is analyzed and evaluatedrespectively. The results show that the grain structural integrity of the solid rocket motor meets the design requirement satisfaction. |
