This project is being funded by the EU via an FP7 Marie Curie IAPP, to address analysis issues associated with vehicle  noise, vibration, and harshness (NVH).

This forms an important part of vehicle design and refinement. A particular problem is how to predict the NVH characteristics of production vehicles, since normal manufacture introduces uncertain variability into vehicle geometry, material properties, and suspension components.  Lightweight vehicle structures are prone to vibration and interior noise problems which unresolved, can adversely affect customer acceptance and driver safety.  Measured NVH characteristics of production vehicles exhibit noticeable scatter. Nominally identical vehicles can leave the assembly-line with widely different NVH characteristics.  In vibro-acoustics, the frequency range is classified as low, mid, or high frequency.    

This project is exploring new computational tools to handle the dynamic uncertainty across the entire frequency range.
