Modal Analysis of Vibration and its Program Development in Power Transformer Core

Abstract:

In this paper, based on the modal analysis combined with power transformer product structure, using the empirical formula calculation method and finite element simulation analysis software calculates the natural vibration frequency of power transformer core, respectively, while making the VB language as a tool to develop the calculation software of natural vibration frequency of power transformer, provides a strong support for product tenders, design and optimization.
