Design of a piezoelectric actuator using topology optimization

This study investigates the optimal topology for a piezoelectric actuator mounted on a cantilever beam under a concentrated static load at the tip. The project consists of two major parts: implementation of the control law into the commercial finite element code ABAQUS and studies in topology optimization. The first part gives a derivation and explanation of the implementation of static feedback control. The result is compared with a derived analytical solution. The second part examines the results of topology optimizations with different geometries and constraints. Thus, this study develops fundamental understanding of advantageous shapes for optimal performing piezoelectric actuators.
