Vibration Prediction
NVH-optimized components are essential to prevent adverse effects such as bending, twisting, rattling, etc. that lead to reduced testbed performance.
Noise Radiation
AVL's NVH simulation experts not only calculate vibrations, but also predict the resulting sound emissions into the test environment.
Soundfield Estimation
Regulatory and project-specific requirements dictate that certain noise limits must be met in certain areas inside and outside of buildings. Our experts can assist in providing an understandable estimate of the expected noise level.
The integration of NVH simulation in the early stages of a project can support in decision-making process. It is also a valuable tool for optimizing components and finding design weaknesses.
AVL provides simulation support for the following tasks:
- NVH-optimized design support for individual components and assemblies
- Calculation of sound radiation of components and assemblies
- Estimation of sound level distribution inside and outside rooms up to whole buildings
- Estimation of noise levels outside buildings
- Experimental validation of the simulation results
Concept Evaluation
Every beginning is hard, and many ideas need a closer look to determine which concept is the best. At AVL, we evaluate several approaches to solve NVH problems, from single components to large systems.
Rapid Prototyping
We accelerate your prototyping process using predictive design studies.
Risk Mitigation
Some design decisions cannot be undone or are very expensive to correct. Using our simulation tools, we provide guidance to make fact-based decisions.
Visualization
Visualization helps to better understand complex deflections of structures. We can visualize key NVH properties such as sound propagation, bending modes, shape deflection, and torsional vibration.
The skilled use of modern NVH tools can give great insights and perspectives. In our experience, the simulation supported design of NVH test systems is the most optimal way to create class leading NVH testing equipment.”
