Numerical Simulation of Vibration Control in Rotors Using Bearing with Shape Memory Effect 2008-36-0334
The shape memory phenomena that some materials possess have allowed their use in numerous applications. In the vibration field, we have the control in which the actuator consists of Shape Memory Alloys (SMA). However, the application of these actuators in vibration control in rotors is not very exploited. Thus, in this paper, we present a methodology for vibration control in rotors using a finite element model to compute the complex response of the system when it is subjected to unbalance forces. The vibration control is performed by controlling the stiffness of the bearing involved with springs made of SMA materials.
