Abstract
The Noise, Vibration and Harshness (NVH) profile of a vehicle is a key metric by which customers rate vehicle performance. Several sources contribute towards this profile, including wind, drivetrain, rolling, ancillary systems, etc. With the advent of the electrification era rolling noise is set to become a dominant source of noise for electric vehicles, due to the phasing out of the internal combustion engine. Interaction between the road and tire contact patch results in excitation of tire natural frequencies. The resulting vibrations are transferred through the wheel centre to the knuckle and subsequently through the vehicle to the cabin. Automotive OEMs rely on experimental and computational tools which can aid in the vibro-acoustic design of their vehicles in order to meet customer demands for quieter vehicles and adhere to traffic noise emission regulations.
Siemens Industry Software currently offers a combined test and model-based solution for tire NVH for the assessment of structure-borne noise
