Challenge

Electrification & Noise Reduction

With the transition to electrification, traditional powertrain noise is largely eliminated. While this creates quieter vehicles, it also exposes previously masked noise sources such as road excitation, wind turbulence, cooling fans and driveline whines that were previously masked. As a result, OEMs are investing heavily in advanced NVH (Noise, Vibration, and Harshness) technologies specifically for EVs.

Electrification & Noise Reduction

Implications

  • appearance of new dominant noise sources, such as tire/road noise, e-motor whine, gear whine, inverter noise and cooling system noise
  • shift from masking to source control
  • the use of lightweight materials versus acoustic performance
  • battery and drivetrain integration effects, including mounting
  • perceptual and brand-level challenges

Opportunities

  • virtual NVH-development and simulation, combining CAE-based models and test-based models
  • advanced material and structural optimization
  • multi-attribute, multi-objective development, looking at NVH, Ride & Handling, durability and weight (cost) in a holistic way
  • parametric design and sensitivity analysis

How VIBES can help

Reduce the need for complex and inaccurate numerical models

What do we do?
We break complex systems down into parts that can be accurately modelled separately. Here we use test-based models to accurately model complex parts, and numerical models for simple parts. Combined, these component models result in an assembly suitable for highly accurate NVH-analysis.

Our value
We help manufacturers avoid spending time and costs on trying to accurately numerically model complex parts that become available, avoiding false accuracy and enabling highly accurate NVH-analysis.

Our experience 
We have developed advanced methodologies to enable Hybrid Modular Modelling and are regarded as industry leader. We have demonstrated the strength of our methodologies at many manufacturers.

Our solutions & software products
To reduce the need for complex and potentially inaccurate numerical models, we would apply: Hybrid Modular Modelling, and Frequency-based Substructuring. These solutions are implemented in DIRAC and COUPLE software with full customer success support.

Enable performant measurement of test-based models

What do we do?
Our software enables innovative Virtual Point Transformation (VPT) while performing NVH measurements. This considerably increases efficiency of the measurements (“VPT as you go”) as well as their effectiveness (highly accurate virtual points).

Our value
Applying our software typically results in NVH measurements, modelling and analysis being done 5 times quicker, with a noticeably higher accuracy.

Our experience 
Since 2016, we have been developing innovative methodologies for NVH-measurement, modelling and analysis, as well as best-in-class NVH software to apply our methodologies. Many large OEMs have since started using our software.

Our solutions & software products
To enable your performant measurement of test-based models, we would apply: Test-based Modelling & Virtual Point FRF Modelling. These solutions are implemented in our DIRAC software with full customer success support.

Reduce inaccurate and unusable NVH data

What do we do?
We apply test-based modelling measurement methodologies, supported by easy-to-use software solutions, that reduce inaccurate and unusable NVH-data. We provide engineering, consultancy and training services to enable our clients to make optimal use of our methodologies.

Our value
Applying VIBES solutions and software considerably increases NVH-data accuracy compared to the industry standard and reduces unusable data by 60%. Unlike legacy measurement systems, the quality checks in our software give you direct insight into the quality of your test-based models. By integrating these checks in your measurement routine, you recognize problems early and do not need to restart testing from scratch. This provides engineers with user-friendly insight into any measurement problem, guaranteeing data accuracy for further processing. You can examine the quality of a measurement done by others (colleagues or suppliers) much better with 3D images and related photos and Virtual Point Transformation quality indicators.

Our experience 
We have 10 years of experience in improving NVH-design, through highly accurate and time-efficient hybrid methodologies, software solutions and services. We have demonstrated the accuracy and efficiency of our methodology at many manufacturers and suppliers.

Our solutions & software products
To reduce inaccurate and unusable NVH data, we would apply: Test-based Modelling. This solution is implemented in our DIRAC software with full customer success support.

Best-in-class NVH designs

What do we do?
We apply hybrid simulation methodologies, supported by proprietary software solutions, to enable hybrid modular modelling. This reduces time and money spent on noise reduction and enables best-in-class NVH-designs.

Our value
Applying VIBES solutions and software avoids design time delays and typically results in 400% higher simulation accuracy in the mid and higher frequency range and 40-60% reduction in the number of physical prototype tests.

Our experience 
We have 10 years of experience in improving NVH-design, for many manufacturers, through highly accurate and time-efficient hybrid methodologies, software solutions and services.

Our solutions & software products
To make best-in-class NVH designs available to you, we would apply: Test-based Modelling, Source Description and Transfer Path Analysis. These solutions are implemented in our DIRAC, COUPLE and SOURCE software products with full customer success support.

Virtually optimize components in a measured assembly to avoid testing physical variants

What do we do?
Our proprietary software enables insightful modification of components, by easily replacing these components in a virtual model of the (measured) assembly.

Our value
By enabling virtual modification of components in a measured assembly, we enable quick and easy optimization of the NVH-behavior, Ride & Handling and car quality throughout the vehicle development process. Thus, we facilitate effective and efficient design and development, helping to avoid delayed product launch.

Our experience 
We have developed a unique and innovative Hybrid Modular Modelling technique that allows virtually optimization of components in existing physical assemblies. We have demonstrated the strength of our methodology at many manufacturers and suppliers.
