Improving the design of sound & vibrations in high-tech engineering
The VIBES Methodology allows engineers to couple measured FRFs with simulated FRFs. Engineers are able to use powerful hybrid modeling and simulation strategies with significant improvement in quality of sound and vibration prediction of complex products. Late-phase sound and vibration troubleshooting is avoided, fewer iterative design cycles are needed, saving time and resources. All in all making reliable full-vehicle models available earlier in the development process.
VIBES.technology is the expert in the modular characterization of sound & vibration for automotive and high-tech industries. We are leading experts in:
- test-based modeling – FRF, modal like, measurements on passive components
- source characterization – blocked force descriptions for active components
- dynamic substructuring – combining multiple component FRF models to build up a system
The VIBES Methodology combines all technologies mentioned above and with it, VIBES’ engineers are improving the reliability, time-efficiency and cost-effectiveness of sound & vibration R&D.
The VIBES methodology
VIBES has a modular approach towards sound & vibration design. This allows a clear separation of responsibilities and reduces the number of measurements required.
A modular way of working
Using the VIBES Methodoloy, a modular way of working, engineers obtain modular descriptions of individual components, with Blocked Forces being the independent quantities describing the active vibrations of the source.
- Using Frequency Based Substructuring, component descriptions are combined to predict the behavior of a full vehicle in a modular way.
- To further reduce costs, engineers can even combine measured and simulated component models, for example using the Virtual Point method.
- This has the added benefit of giving insight in the model quality and reliability, which is implemented in the DIRAC software.
We proved the success of the VIBES Methodology in projects for several major players in industry and we are now leading experts in applying component-based TPA and Blocked Force technology.
Right now, the industry is also picking up on these trends. With smart sensor data fusion (which is done real-time in DIRAC) typical drawbacks as directional errors in impact hammer testing or the application of forces at connection points are efficiently dealt with – with the added benefit that the engineer gets real-time insight in the measurement quality too.
We are excited to see that our enthusiasm for the continuous development and implementation of modern TPA methods is shared and appreciated across the industry. VIBES has built a professional team of dedicated experts and researchers, working together with leading partners in the industry to build the right tools and knowledge that help our clients win in competitive markets.
