Sebastian Gonzalez: Violin shape optimisation

Violin shape optimisation with Finite Elements Modelling and Artificial Intelligence We will present the results of two different approaches for violin top plate optimization. On the first half of the talk, starting from a outer 3D scan of the Messiah, an algorithm for optimizing the frequency response of the top through its thickness is presented. Then, this time starting from the outline of the Messiah, a method for the prediction of the frequecy response using Artificial Intelligence will be shown for constant thickness plates. In particular, how the data set is created, the relation between shape and modal response, and a possible representation of the violin outline from Principal Component Analysis will all be detailed. If time allows, we can see how historical examples clusterise in the PCA diagram.
