| 中文摘要: |
| 主要从发动机装药结构的损伤性能有限元仿真分析方法、蠕变损伤试验设计以及蠕变损伤研究方法等3个方面综述了固体推进剂蠕变损伤性能研究进展，指出蠕变效应会导致推进剂内部含能颗粒与基体之间出现脱湿细观损伤，进一步总结了现今蠕变试验研究和宏细观蠕变性能数值模拟中的不足。分析认为，蠕变损伤试验研究的难点在于研究推进剂材料级试验结果与实际装药结构中推进剂蠕变效应的对应性和数据映射关系，推进剂损伤数值模拟的难点是推进剂含损伤蠕变多尺度本构模型的建立，以及在自重载荷下药柱形变预测计算的应用计算问题。最后提出的建议可以为开展长期贮存条件下推进剂蠕变损伤性能研究提供一定的参考。 |
| 英文摘要: |
| In this paper, the research progress of solid propellant creep properties was reviewed from three aspects:finite element analysis method, creep damage experiment design and creep damage research method. It was pointed out that the creep property lead to the meso-damage between particles and matrix in the solid propellant. The shortcomings in the present creep experimental research and numerical simulation of multi-scale property were summarized. The analysis showed that the creep experimental research difficulty lied in the research on the correspondence and data mapping relationship between the experimental results of propellant material grade and the creep effect of propellant in the actual charge structure; while the numerical simulation difficulty was the establishment of a multi-scale constitutive model of propellant damage creep and the application calculation of deformation prediction of propellant columns under self-weight load. Finally, the suggestions can provide some references for the study in solid propellant creep damage properties with long-term storage. |
