In recent years, the vibro-acoustic comfort has become an increasingly important aspect in the design and development of new vehicles; this, along with the need of the industry to minimize time and engineering costs, creates the ideal scenario for the use of the CAE approach, aiming to study, forecast and solve NVH issues.
- Prevent to Reaction (Support to Design)
Thanks to NVH CAE you can follow the development of a power unit from its early stage through virtual simulation of its dynamic behavior. This allows not only to provide for any faults and / or failures, but also to advance implementation of changes usually carried out in later stages of the project. The advantage of avoiding lengthy and costly loop for prototyping and experimentation, is clear.
- Problem Solving (Support to Experimentation)
NVH CAE proves to be a useful instrument even for problem solving. If, during the testing phase, it’s easy to highlight the acoustic anomalies, it is not so easy to identify their origin, because of the complexity of modern powertrains. On the contrary, through virtual simulations you can isolate the behavior of a single component and evaluate its proper functioning.
