报告内容摘要:

Smart material systems are now being applied to the design of high performance structural systems. Among the diverse features of smart materials and structures, this talk focuses on smart material systems that pertain to vibration monitoring and control.

Firstly, micro vibration problems in satellite will be addressed. The vibration source and characteristics are presented. In addition, the developed micro vibration control devices are introduced.

Secondly, a new type of shock and vibration isolator using SMA materials will be introduced. A novel frequency tuning method of the isolator is proposed to achieve both shock attenuation performance and avoidance of the vibration amplification.

The last topic is the full-field real-time measurement of vibrations of a structure based on fiber-optic technology will be introduced. Optical fibers are the preferred sensor material for vibration monitoring because optical fibers are small and lightweight, consume less power, and are immune to electromagnetic interference. Real-time shape estimation of several composite structures including a wind turbine blade model was accomplished at SSHS KAIST using strain data gathered by the arrayed fiber Bragg grating (FBG) sensors.

If time allows, other research activities at SSHS lab. will be also introduced very briefly.
