| Abstract: |
| It is desirable and important to design a variety of actuators for certain driven requirements in engineering applications.In this paper,a topology optimization method is presented for designing actuators driven by piezoelectric materials.By combining topology description function method and RAMP (Rational Approximation of Material Properties) material model,an optimization model simultaneously optimizing the distribution of piezoelectric driven component and layout of flexible mechanical structure is formulated.The goal is to design the layout of the flexible structure coupled to piezoelectric driven component and the position of the driven components that maximizes the output displacement in some specified direction.Numerical examples are presented to demonstrate the validity of the proposed approach. |
