A new alliance for innovation
Müller-BBM VibroAkustik Systeme partners with VIBES.technology to couple measured FRFs with simulated FRFs
Munich, Germany and Delft, Netherlands Müller-BBM VibroAkustik Systeme and VIBES.technology are proud to announce their partnership to push new engineering technology to the market – Experimental Dynamic Substructuring. This brings together two leading companies in the field of experimental and numerical testing, leveraging the proven strengths of each.
The partnership unites Müller-BBM VibroAkustik Systeme’s long-standing expertise in acquiring, analyzing and managing highly accurate, high-frequency physical data based on an open platform architecture with VIBES’ expertise in substructuring technology.
“Currently, trends such as electrification, increasing number of vehicles and variants, and lightweight materials, require a more modular approach in NVH engineering. This means simulation and testing will merge,“ said Andreas Ansorge, CEO Müller-BBM VibroAkustik Systeme GmbH.
Müller-BBM VibroAkustik Systeme provides the infrastructure for enabling the seamless data access across multiple data sources and applications in a standardized, efficient way. Furthermore, sustainable data management based on cloud technologies will also be possible. Andreas Ansorge continues: “This gives us the freedom and ability to collaborate with technology leaders. These partners can integrate high-quality physical data from our PAK device cloud or access recorded data from our PAK cloud.”
“The vision of VIBES.technology is to bring promising, innovative methods for sound & vibration testing and simulation to the industry. Our ultimate goal is to significantly decrease the engineering time and effort required in sound & vibration design of vehicles – thus reducing overall development costs and time-to-market”, said Maarten van der Kooij, Head of Product Development and one of the founders of VIBES.
Maarten van der Kooij continues: “VIBES envisions a solution where source and receiver subsystems are engineered separately and combined virtually, using Experimental Dynamic Substructuring combining the best of both worlds. Depending on the complexity of a component and the availability of prototypes, a component model is generated either from simulation (= FEM model) or test (= test-based model). Experimental Substructuring thereafter combines all component models to obtain a virtual acoustic model of the vehicle’s NVH.”
Experimental Dynamic Substructuring introduces a new era for testing, as measurements may serve as an input to simulation rather than a validation process. Beyond that, Component TPA becomes the next level of engineering along with Blocked Force Characterization. Component TPA allows characterization of components on test benches, independent from test bench or vehicle. It serves as a perfect input to the Experimental Dynamic Substructuring models generated.
In order to enable these techniques, VIBES.technology created an innovative software application, DIRAC, for test-based sound and vibration measuring. This is the first software of its kind which enables engineers to build accurate FRF models from measurements. DIRAC runs on Müller-BBM VibroAkustik Systeme’s platform architecture of PAK device cloud and PAK live technology.
“Our customers benefit greatly from the combination of high-quality, multichannel data acquisition, processing, and management with the use of highly specialized tools, such as the DIRAC software from VIBES.technology,” said Andreas Ansorge. “The launch of DIRAC is a huge technological step forward and a powerful milestone in our collaboration. It gives us the opportunity to enhance our ability to drive innovation and assist companies across the industries in their R&D process.”
