Abstract

Dynamic performance has become a significant criterion in the design of many machines. In this paper an integrated approach utilizes modal testing results and finite element modelling into a system analysis routine to give the engineer a usefull tool to select design modifications and to predict the dynamic performance of a new machine. This approach can be used for redesign of existing machines or the development of new systems. A specific application of the method on a harvester sha-ker is described.
