A new simulation method to treat the fluid-structure interacted nonlinear problem is presented. In this method, the transformer coils are modeled as a multiple-degree-of-freedom system, which consists of lumped masses and nonlinear springs. The insulation oil in the gap between the lumped masses is regarded as a one-dimensional uncompressible fluid flow including viscous resistance. A good correlation is achieved between the experimental and analytical results using an actual scale model transformer in the verification.
