Teste NVH — Ruído, vibração e aspereza  

Vibration energy from an engine travels into the structure, through the engine mounts, and through the car seat into the driver. But energy from the same source can take a similar path through the structure to become acoustic noise when it is amplified by the cabin. Both interior and exterior noise are critical and subject to regulation. There can be too much or – in the case of EV's – too little noise. Noise and vibration characteristics of components, sub-assemblies and the entire vehicle need to be tested at an early stage of development to avoid costly design changes and a delayed go-to-market. Therefore, optimizing these factors is not only of utmost importance for the overall user experience of the vehicle, it also ensures the finished product will meet noise emission targets and certification requirements. HBK offers a comprehensive suite of best-in-class NVH test equipment and highly skilled engineering service.

Acoustic quality analysis and vibration production line testing (PLT) is an integral part of manufacturing automotive components. Besides maximizing the production line yield and cost effectiveness, they ensure the quality and customer acceptance of the entire powertrain.

HBK solutions for End-of-Line (EoL) provide full functional and acoustical behavior analyses of each eDrive unit directly in the production. Automatic evaluation of path/fail criteria enable maximum quality and high productivity. In case of failure digital twin model can identify the root cause.
