Novel reduction techniques for exterior vibro-acoustic models and their use in model-based sensing

Описание: By smartly combining physics based numerical models with measurements, it is possible to combine the advantages of both approaches and create a virtual sensor that can accurately estimate vibro-acoustic quantities, such as acoustic pressure and sound intensity. This is possible even on locations where no sensors are placed. During his PhD, Sjoerd van Ophem derived the algorithms that are required for making this possible. An important step is the derivation of accurate but rapid physics based numerical models. Therefore, finite element models are used that are reduced in size with novel reduced order modeling techniques.
