航天器虚拟动态试验技术研究及展望

文章简要回顾了航天器结构动态设计技术的发展,并且指出随着现代航天器越来越复杂,数值分析方法与动态试验方法都无法满足设计的要求.为了解决这个问题,必须采用虚拟动态试验技术.文中较详细地介绍了复杂结构模型修改新技术、虚拟模态试验技术和振动台虚拟振动试验技术.文章最后还对该领域未来研究方向进行了展望.

A Review on Virtual Dynamic Test Techniques for Space Vehicles

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.
