摘要：

Active Strain Energy Tuning (ASET) using Shape-Memory Actuators has been proposed for the vibration control of 'smart' composite structures. This paper presents preliminary experimental measurements on some simple prototype SMA hybrid 'Smart' structures. The results confirm previous modelling and show that ASET can indeed be used to control vibration characteristics. The most significant control mechanism appears to be real-time shifting of resonance frequency. This practical implementation also reveals additional factors which must be considered when designing such structures.
