摘要：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.
