Abstract

The objective of this research is to determine the optimal topology of a piezoelectric actuator on an elastic base beam undergoing harmonic excitation. The piezoelectric actuator is modeled using finite elements. This preliminary research provides insight into the potential of optimized piezoelectric actuators. Results from topology optimization show that significant improvements in vibration amplitude reduction are possible by optimizing the actuator damping layer topology.
