Investigation of the mathematical model of bending oscillations of the oil tanks' walls in the transformers considering nonlinear dissipative forces

The results on correct well-posedness of the problem about small bending oscillations of the oil tank walls of the transformer in the nonlinear medium are obtained. Sufficient appropriateness of this model to the real one is proved basing on the computer simulation. It is also demonstrated that nonlinear medium produces damped oscillations leading to the anharmonic processes in the system.
