摘　　要：本文给出航天结构热力力学的应用背景和工作任务．首先讨论它的先决条件：载荷谱和材料特征．其次介绍一些典型的热力力学结构：再入热防护系统，轨道空间结构，以及碳纤维增强复合材料板件．然后，介绍热力力学的工作内容：热分析，经典结构分析，热损伤力学，以及热力力学耦合和结构试验．最后为简单展望．The background and tasks of thermomechanics of aerospace structures are presented. First its prerequistes are discussed:load spectra and materialCharacteristics.Then some typical structural concepts are introduced,such as:heat protection system during entry, orbital structure, and the use of carbonfiberreinforced polymers in airplanes. From these concepts the tasks of thermome-chanics of aerospace structures are deduced: thermal analysis, structural analysis,thermo- damage mechanics, thermomechanical coupling analysis as well as struc- tural testing. Finally, its prospect is given.
