Abstract

The three-dimensional vibration of circular rings coupled by elastic elements is investigated in this paper. The vibration characteristics of a single circular ring are examined first analytically and experimentally and then used as building blocks for a stack of concentric rings connected by elastic insulators, which is used as an approximate-model of a disk-type transformer winding. The key outcomes of this research are a more realistic model for transformer winding vibration and determining its three-dimensional vibration characteristics. The model is also verified experimentally. An experimental-based numerical method is also developed for identifying the stiffness and damping properties of the elastic elements.
