计算机模拟固体推进剂贮存老化的研究进展

Review on Computer Simulation of Solid Propellant Aging

分析了微观和介观层面常用计算机模拟方法的特点及局限性,重点介绍了这些方法在构建固体推进剂微结构、判断组分相容性、研究交联降解机理及界面相行为等方面的应用,并展望了计算机模拟方法在固体推进剂老化研究中的发展前景,认为贯穿微观、介观和宏观的多尺度模拟研究将是今后老化研究的重点。

The characteristics and limitations of microcosmic and mesoscopic molecular simulation have been introduced.Applications of these simulation methods,such as propellant microstructure construction,estimation of component consistency,research of micro-mechanism on binder＇s cross linkage,degradation and phase change were detailedly mentioned.The future development of the application of computer simulation on propellant aging research is multi-scale simulation including bridging the gap between the micro-,the meso-and the macro-scale simulation techniques.
