Challenge
Increased customer expectations for comfort
Reducing noise and vibration is key in the automotive world. Quiet, refined, and comfortable driving experiences, in highly durable cars, are now baseline customer expectations.
Increased customer expectations for comfort
Implications
- In a very competitive market, OEMs need to design vehicles with an optimal balance between Noise & Vibration behavior, Ride & Handling, susceptibility for fatigue and material costs.
- OEMs must dramatically reduce road, wind and HVAC noise, which have become more noticeable in EVs due to the absence of engine masking.
- Comfort expectations mean NVH issues must be eliminated early in the design phase, not during late prototypes.
- OEMs need to avoid weight increase, by finding the right balance between innovative design and optimal NVH-behavior.
- Comfort expectations raise the pressure to control non-traditional noise sources.
- NVH is no longer just a technical requirement, it’s a strategic differentiator directly tied to customer loyalty.
- With time and money being scarce, it is essential to reduce noise and vibration as effectively and efficiently as possible.
Opportunities
- OEMs must invest in CAE-based acoustic simulations, digital twins and FRF-based system modeling to predict tonal peaks, booming modes and road noise behavior far earlier than before.
- With modern NVH-methodologies, such as Hybrid Modular Modelling, manufacturers can meet the rising standards for comfort and perceived quality. Thus they can handle the higher-frequency noise challenge typical of modern electric and hybrid systems.
- They can optimize multi-objective vehicle design, by virtually modifying vehicle components, systems and assemblies, for example by reducing mass or modifying stiffness. In one go they can assess the impact of these modifications on the overall vehicle performance.
- As such, they can optimally balance NVH-behavior, Ride & Handling and durability, when designing and analyzing vehicle attributes such as powertrain, tires/wheels, suspension and auxiliary components.
- They need to be certain that the results they achieve in NVH-testing and simulation are “first time right”.
How VIBES can help
Adopt a multi-objective, multi-attribute design process
What do we do?
Our advanced proprietary software solutions enable highly accurate Hybrid Modular Modelling. Our highly-qualified engineers help car manufacturers optimize multi-objective, multi-attribute vehicle design.
Our value
Our solutions enable car manufactures to better understand the balance between vehicle objectives such as NVH-behavior, Ride & Handling and durability, when analyzing vehicle attributes such as powertrain, tires/wheels, suspension and auxiliary components.
As such, we help them reduce cost in the development process and build optimal products at reduced production cost.
Our experience
Since 2016, we have developed and optimized Hybrid Modular Modelling and applied it for various car manufacturers, demonstrating the potential of combining test-based and numerical models to optimize multi-objective, multi-attribute vehicle design.
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.
Our solutions & software products
To virtually optimize components in a measured assembly to avoid testing physical variants, we would apply: Hybrid Modular Modelling, Source Description and Transfer Path Analysis. These solutions are implemented in DIRAC, COUPLE and SOURCE 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.
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.
