| 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. |
