Noise, vibration, and harshness (NVH)

In recent years, vehicle’s behavior in controlling the noise and vibrations is more and more taking the attention of auto manufacturing companies. On the other hand, customers pay extensive attention to the acoustic behavior of the vehicle and consider it an important criterion when buying automobiles. In JETCO, the NVH group is tasked with enhancing the NVH control capability of vehicles manufactured in Iran, and for this purpose, it utilizes different simulation methods and experimental techniques.

“Intelligent troubleshooting of End-of-Line (EOL) gearbox test system”, “analysis of noise transmission paths to mitigate interior noise levels of Peugeot 207”, and “reduction of the aerodynamic noise level in DENA+” are among the most important projects of this group.
