Analysis of the dynamic and noise emission behaviour by experimental modal analysis and finite-element-analysis of press structure and derivation of proper noise reduction techniques

With the help of the dynamic and acoustic measurements a complete overview of the aspects in huge machine tools, especially at presses could be achieved. Not only vibration transmission within the structure of the press was investigated, but also the effect by changing specific properties of the machine tool, like rpm of the drive train, counter balance system etc.

In addition a Modal Analysis was performed to identify the modal vibrational behaviour of the press as a whole. Therefore, not only local effects have been analysed but the complete interaction of the press parts.

These results performed with the help of several measurements campaigns at the FAGOR workshop, give also a basis for the complete-Finite-Element Model, which WZL performed from 2-D-Drawings, which FAGOR provided WZL. By the help of this FE-model some effects could be investigated and it was the first step in building a complete Multi-Body-Simulation of the press structure and the press drive train.
