Abstract : Modal analysis is a widely used tool for the analysis of the vibrational and noise behaviour of mechanical structures. In experimental modal analysis, the dynamic behaviour is studied by means of a model, based on transfer function measurements. One of the main limitations of the experimental technique in a lot of applications is the highly specialised equipment and the corresponding investment. The aim was to design a multichannel data-acquisition system front-end for our H.P.100 computer (Digital Data Harvester). This system should be easily expandable and flexible enough to be used with a wide range of mini and micro computers. Although the original design purpose was to develop such a system for Modal Analysis, its application area is likely to be much wider.
