Abstract:Within the framework of the OMID joint project (1999 - 2002) funded by the BMBF, a universal, fluidically driven actuator plate is being developed in cooperation with the project partners of Bartels Mikrotechnik GmbH and ANSOFT GmbH. This actuator plate is to be applied as an integrated microsystem component for the conversion of fluidic energy into mechanical energy. Applications of the micro actuator include tactile arrays for high-resolution Braille displays or high-pole micro relays. The present contribution deals with topology optimization using evolutionary algorithms and a parameterizable finite element method (FEM) simulation model. The use of evolutionary algorithms requires short simulation times for evaluation. For this reason, close-to-physics simulation models based on discrete element methods cannot be used so far for this purpose, due to their usually long computation times (compared to higher models). In contrast to this, the parallel version of the GADO (Genetic Algorithms for Design Optimization) optimization tool developed by our Institute allows for the use of close-to-physics simulation models in optimization with a global search strategy.
