This paper presents two different models of the structural dynamics of a PUMA 560 robot: a frequency response, and a modal model. The first consists of a set of frequency response functions measured from the structure. The eigenvalues and the mode-shape, which comprise the modal model, are extracted from the response model. In addition to these linear models, the paper describes the nonlinear characteristics of the structure. How the non-linearities affect the measurement technique and the model accuracy is also described.
