Abstract:
Based on the apparent elasticity method, deals with the three dimensional coupled vibration of the oblique wedge-like transformer with a large dimension rectangular section. The frequency equation of the fundamental modes of vibration is derived. By using the finite element analysis software Ansys, three sets of the oblique wedge-like transformer are analysed. Compared with one-dimensional theory, the results of three-dimensional theory are closer to that of the finite element analysis when the cross section is large, and the larger for the dimension, the better for three-dimensional theory.
