摘要

Dynamical analysis of prototype components and assemblies is a very important step in design optimisation for noise, vibration and comfort applications. For global response predictions of assembly systems, it is important to start from individual models which one is confident with. Finite element model and test correlation are therefore important steps in this process. This supports the user to look for possible inaccuracies or inconsistencies during the modelling process. An important further step in this dynamic test-analysis integration is to use this correlation information to further tune the finite element model, certainly in areas where the analyst has less confidence in the modelling parameters. In this step, optimisation strategies are very apt to improve these parameters in order to have the model better correlate with the prototype measurement values. The paper discusses the process of using the MSC/Nastran solution 200 optimisation strategies for this updating and tuning process. For given target criteria, obtained from the test-analysis correlation step, like resonance frequencies, frequency response function amplitude differences, and for a selected set of physical parameters, as defined within the LMS Link environment, the necessary input data for the solution 200 process are generated. The optimisation is fully driven within the solution 200 context. The integration of solution 200 within the LMS Link context therefore offers the full advantage of the strong optimisation capabilities of MSC Nastran, integrated with the test environment within LMS Link.
