Abstract
The main purpose of this study is to analyze the dynamic performance of Adaptive tuned vibration absorber (ATVA). For analysis, a baseline model consists of a base excited single degree of freedom system coupled with an ATVA mode prepared. Shape memory alloy (SMA) which has a variable frequency with respect to temperature, is used for adaptive tuning after its material characterization. Tests are performed to determine the peak Transmissibility by varying the temperature of SMA wire i.e. stiffness. The results showed that the peak Transmissibility of ATVA is nearly 46% lower than low temperature. Results further showed that increase in stiffness reduces the vibration levels at higher temperature, also the frequency span increases.
