Abstract: This paper reviews the development of structural dynamic designing techniques for space vehicles, and it is shown that with more and more complicated modern space vehicles, both numerical analytical methods and dynamic test methods become incapable of satisfying the design requirement. So the virtual dynamic test techniques must be adopted to meet the demand. The new techniques are described in detail, including the mathematical model updating for complex structures, the virtual modal test techniques and the virtual vibration test techniques of shaker. The outlook to the future researches is also given.
