NUMERICAL AND EXPERIMENTAL STUDY OF SHAPE MEMORY ALLOY ACTUATED DVA FOR VIBRATION CONTROL OF CANTILEVER BEAM

Shape memory alloys (SMAs) are one of the most widely used smart materials in many applications because of their shape memory effect property and pseudo elastic behaviour. This paper describes numerical and experimental platform which analyzes and controls the vibration of a Shape Memory Alloy (SMA) actuated cantilever beam. The system consists of cantilever beam fixed with C Clamp. The shaker is used to generate real time vibration with the help of function generator. The SMA springs with mass is attached at the free end. The experiments were carried out by using SMA and conventional spring. The FFT, accelerometer and non contact type displacement sensor were interfaced with PAK software to note the results. According to the experimental setup the cantilever beam with spring mass system is modelled in ANSYS Workbench R15.0. And harmonic response analysis was done, and results are compared over range of frequencies.
