摘要

建立热障涂层应变的数学本构模型及材料模型,进行了热障涂层的热力学分析,得到设定时间内的变化云图,得出热障涂层的等效蠕变是随着温度的增加而增加的,且热障涂层内外层的温度与时间的变化规律与定义载荷变化规律一致这一结论,所获得的分析数据为热障涂层的进一步实验分析及热障涂层的优化设计提供了一定的理论依据。
        The strain′s mathematical constitutive model and material model of thermal barrier coating were established,the thermodynamics analysis of thermal barrier coating was carried out,and the strain nephogram of the coating in setting time was obtained,which indicated that the equivalent creep of barrier coating was increased with the increase of temperature,and the relationship of the temperature of thermal barrier coating and time is consistent with the load change rule.The obtained analysis data also provides some theoretical basis for further experimental analysis and optimization design of heat coating.
