摘　　要：总结了近年来航天动力学分析、试验方面的最新成果。按照航天飞行器寿命期不同阶段的特点,对动力学试验与理论建模、分析预示、试验技术、测量方法,特别是地面气候复合以及高速飞行热结构动力学分析与试验方面的工作进行归纳,并指出存在的不足,以及未来发展的方向。通过工程研制中的分析与数据积累修正,在建模分析预示、条件制定以及测量技术等方面取得显著成果,但由于飞行器复杂,在准确精细预示方法、热结构预示与试验技术方面以及气候复合状态下的分析与试验方面尚需大量研究。应坚持理论与试验、工程研制与研究相结合的方式,不断完善持续改进,实现动力学精细化预示与天地一致性试验。This paper summarizes the recent achievements in astrodynamic analysis and tests. According to the different characteristics in each life period of aerospace craft, the paper summarizes the dynamic tests and theoretical modeling, analysis and prediction, test technique and measurement methods, especially the thermal structural dynamic analysis and tests of complex ground climate and high-speed flight. The related shortcomings and future development directions are given. By means of engineering analysis, data accumulation and data correction, much improvement has been achieved in environmental prediction, environmental condition making, and measurement technology. However, due to complexity of spacecraft, much research work still needs to be done in aspects of methods for high-accurate prediction, thermal structural prediction and tests, and analysis and tests under complex climate conditions. To achieve high-accurate prediction and ground-fly-agreeing tests, the combination of theory and tests and the combination of engineering development and research should be insisted, and also, continuous improvement is required.
