Utilizing Modal Testing in System Analysis to Affect Design and Predict Structural Performance 801126

Dynamic performance has become a significant criterion in the design and evaluation of structures. In this paper an integrated approach of modal testing and system analysis is described which gives the engineer a useful tool to effect design modifications and to predict structural performance. This approach can be used for redesign of existing systems or the development of new structures. A specific application of the method is described which involves the troubleshooting and redesign of a material processing machine which was yielding substandard product.
