The aim of this research project is to develop efficient numerical and simulative design optimisation methods for multiresonant microsystems. Since simulations for these systems are very resource-intensive due to the high-dimensional differential-algebraic system of equations that have to be solved, we use a combination of two modern numerical methods, namely topology optimisation and model order reduction, to speed up the design process many times over. Although we are focussing on multi-resonant microsystems in this project, the methods developed can be applied to a wide range of dynamic microsystems in mechatronics.

    UPDATE: The results of this project have been recognised by the German Research Foundation (DFG) in the form of a funded follow-up project. The follow-up project "optiMuM" started in March 2021.

    Topology optimisation (TO)

    The diagram illustrates a typical application of topology optimisation (TO): stiffness maximisation. Starting from the maximum available design space, TO manipulates the material distribution to find the structure with the maximum stiffness for a given load case and the desired final mass of the structure.

    Model Order Reduction (MOR)

    Model order reduction (MOR) projects the system matrices onto a suitable, significantly lower-dimensional subspace using selected projection matrices V and W. In doing so, the accuracy of the model is only marginally reduced, meaning that using the reduced model instead of the original model drastically reduces computation time.
