SIMPRO/VTT Task 2.3: Optimisation of a particle damper with DEM

    Abstract

    The idea of this study was to show that designing a particle damper using optimisation is feasible with the computational power of current parallel computers and DEM tools. It was shown that the concept works. The Parallel Direct Search optimisation method was able to find the optimal configuration for the particle damper. Also the straight forward parameter study proved to be a viable option. On the other hand it was found that the DEM tools need more development and that the DEM simulation is slower than expected. Also in this study a 5 to 10 times saving for the simulation time was found by showing that it is not necessary to simulate until the transient peeks due to the start are settled out.
