Abstract The optimal design of a piezoelectric linear actuator using parametric optimum method-based finite element method (FEM) was presented. First, the FEM model of the cymbal stack transducer was generated with its initial configuration. The structural parameters were chosen as the design variables and the displacement on the top surface of the transducer taken as the objective function. Second, the zero-order optimization method was chosen as the basic tool of the structural updating. The structural optimization scheme of the cymbal stack transducer was carried out based on ANSYS parametric design language (APDL). Finally, an example of dynamic response analysis was performed on the cymbal stack transducer to verify the structural optimization scheme. The results show that the displacement on the top surface is increased by 32.9% compared with the case of initial configuration.

Significant Time

In the process of using the genetic algorithm for grillage structural optimization, direct calculation was applied to grillage structural strength Check. The combination of genetic algorithm and direct calculation can save significant time in optimization design and strength check, at the same time, optimized grillage structure provides more security.And then this structure optimization scheme was programmed by VB with easy interface. The example indicates the program, being reasonable and feasible, proves the combination's superiority.
