Abstract

A method for steady-state calculation of mechanical or structural systems formulated by the finite element method (FEM) is presented. The procedure introduced is used to calculate the mechanical vibrations caused by the electromagnetic excitation of induction motors. Compared to other approaches, this method enables the free choice of the time discretisation algorithm. The method is presented for second order systems and demonstrated by a numerical example.
