Sound and vibration have a defining influence on our perception of product quality. They are especially well-known aspects in the automotive industry. While traditional combustion engines are gradually getting replaced by hybrid or full-electric drive-lines, other electromechanical (so-called mechatronic) systems make their entrance. As a consequence, the sound experience shifts from low-frequent engine roar to high-frequent humming and whining – a yet unfamiliar experience that calls for redefinition of the soundscape. This thesis presents techniques that aim to implement measurements of structural dynamics and active vibration sources into development processes. This simulation is facilitated by use of Experimental Dynamic Substructuring: a methodology that determines structural dynamic aspects of complete products based on individually measured components.
