Abstract :
This research presents numerical simulation tools used in the research of acoustic guitars in the industrial context. The focus is on describing a virtual prototyping environment that has been successfully used in product development. The main challenge is achieving an acceptable agreement between simulation and measurement of a random guitar taken in the production line. To this end, detailed geometrical modeling and averaged materials parameters values measured from the production line are used. Simulation and measurement results are compared in terms of mode frequencies, frequency responses, and radiation efficiency.
