SOURCE & how it is used by engineers

Software Old days, news days... Modern NVH software SOURCE & how it is used by engineers by Dennis de Klerk, expert in sound & vibration engineering & co-founder of VIBES NVH software has been around for years and the most common used date back to the 80’s. A lot of new developments took place since [...]

The release of SOURCE

Software The release of SOURCE by Maarten van der Kooij, CEO VIBES.technology Over the last two years, our company developed at a remarkable pace: the DIRAC software is being used by most of our clients, we opened a new office in Munich, we are now serving clients globally and most of all, we are releasing [...]

Electric Compressor Source Characterization

Electric compressor Source Characterization Together with a key player in the automotive industry, we have worked on an exciting project, concerned with source characterization using blocked forces. In this article, the successful application of source characterization to an electric air cooling compressor (ELAC) is shown. We took two approaches to compute blocked forces and demonstrate [...]

Characterisation of an Electromagnetic Roll Control with Blocked Forces

Electric compressor Source Characterization The goal of this study is to show the successful application of independent source characterization for an electric air cooling compressor (ELAC). We take several approaches to compute blocked forces and demonstrate the robustness of the characterization. The scope The purpose of this project for ZF has been straightforward. Getting prepared [...]

The Why of SOURCE

Software The Why of SOURCE VIBES developed SOURCE, our newest software application for Blocked Force source characterization and component TPA. Read more about why we developed SOURCE... by our Project Manager R&D, Julie Harvie Source characterization is at the heart of today’s NVH analyses. From direct force measurements on a test rig to free velocity [...]

Maximize your NVH measurement quality (using DIRAC)

Maximize your NVH measurement quality Current NVH measurement processes have been around since decades and do not leverage the possibilities that general advances in technology have to offer. There must be another way, right? In this article we look into regularly used measurements, the facets of those processes that could be improved, and the new [...]

Frequency Based Substructuring of an E-Golf

Frequency Based Substructuring of an E-Golf 2019 was a year filled with exciting techological projects, collaborating with several key players in the automotive industry. Most projects included aspects such as blocked force source characterisation and Frequency Based Substructuring with test-based models. The use of DIRAC and the VIBES Toolbox made all the difference, both in [...]

All-new release of VIBES Toolbox for MATLAB V3!

All-new release of VIBES Toolbox for MATLAB V3! The new VIBES Toolbox for MATLAB offers more Dynamic Substructuring capabilities than you’ve ever had, making it the market’s go-to solution for modular sound & vibration engineering, dynamic substructuring and method development. Some of the new possibilities include: Component Mode Synthesis: import large FE models, create RBE2/3 […]

Case study E-compressor – DIRAC

Predict the NVH performance by combining test data and FE models 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. Our DIRAC software was used to prepare, measure and analyze the FRF measurements. While performing the [...]

New technology and software for blocked forces 

New technology and software for blocked forces VIBES.technology is actively informing the NVH world, at various renowned conferences, on source characterization, TPA and applications to measure blocked forces and FRFs. This article gives an insight in the latest presentations and papers and gives a sneak-preview of our newest software application: SOURCE. Blocked Forces and source [...]
