Optimizing noise isolation concepts for electric climate compressors with substructuring simulation techniques.

Together with a key player in the automotive industry, VIBES showed a successful application of independent source characterization for an electric air cooling compressor.

Using the blocked force approach an overseas OEM was able to predict the NVH performance by combining test data and FE models and reduce interior noise by ~15 dB..

In this measurement campaign we measured the full-electric rear-wheel drive 2021 BMW i4, in order to test COUPLE in an industrial application.

This study focuses on the use of Frequency Based Substructuring to obtain full-vehicle models starting from test data of single components. It is also proved that rubber bushings can be characterized using inverse substructuring.

This project concerned Frequency Based Substructuring and Blocked Force Transfer Path Analysis of the electric drive of an E-Golf.

Volvo is one of the leaders in the transition to electric powertrains, and recently Volvo announced that every new model from 2019 onwards will feature an electric engine.

This study focuses on comparing the acceleration-based in-situ and new mixed indicator Blocked Force determination methods using measurements of an artificially excited electric power steering (EPS).

Using DIRAC’s Virtual Point Transformation, OEMs can now predict in-vehicle EPS sound & vibration performance based on supplier data and vehicle noise transfer functions..

This study focuses on the use of tire noise test benches in the engineering of full-vehicle NVH. We show how virtual points, easily obtained using DIRAC, ensure compatibility between various test assemblies.

We started the development on project COUPLE, which is a two year collaboration between VIBES, the Technical University of Munich and BMW Group. This innovative project was voted by Eurostars as one of the best in Europe!

SOURCE, our software solution for source characterization and component TPA, is developed in a partnership with Lightyear and the features range from vibration source characterization all the way to noise predictions.

High quality Blocked Forces rely deeply on high quality test models, which is where VIBES’ software applications make a real difference. A great example is the one of ZF Friedrichshafen, and how they prepared for Blocked Forces in a collaboration project.
