Semi-active vibration control based on shape memory alloy actuators: Analysis and experimental testing

Research output: Contribution to journalArticleScientificpeer-review

Abstract

Vibration control of civil structures, machines or generators for instance, is a
challenging task when the structure undergoes various loading conditions from normal
operation to extreme loadings like earthquake. Adaptive vibration control for changes in
environmental and operational conditions is capable of achieving optimum performance
in all circumstances. In this study, new numerical methods and novel applications for
semi-active vibration isolators were developed.
The basic idea was to control the
stiffness by changing the kinematic boundary condition of the device. After numerical
studies, two different concepts were developed: a circular frame spring and a cylindrical
elastomer spring. The stiffness control was actuated by shape memory alloy (SMA)
material embedded into the device. Both concepts were verified experimentally.
