Abstract
This paper examines the natural frequencies, mode shapes and modal damping ratios of a specially designed laboratory fixture with integral, welded or glued joints. The influence of these alternate joints on the dynamic properties of an assembly is demonstrated, using experimental, computational and analytical methods. Dimensions of a typical welded joint configuration are varied to study their effects on the modal properties of an assembly. Predictions are successfully compared with experimental modal data. This study should help in selecting the welded joint configuration to meet strength, durability or dynamic design criteria.
