Our cases

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.

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

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, a well-established German automotive supplier, and how they prepared for Blocked Forces in a collaboration project.

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.

Technology training in the field of excavators.

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..

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..
