摘要
基于三维粘弹性有限元模型,应用MSC/NASTRAN软件对某发动机分别在固化降温、燃气内压载荷条件下的装药结构完整性进行分析,并对该发动机在固化降温、燃气内压两种载荷联合作用下的装药结构完整性进行评估。结果表明,该发动机的装药结构完整性满足要求。
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.
