Deformation and Stress Fields in Thin Metallic Partially Fixed Plate Induced by Electromagnet with Constant Flux Obtained by Analytical Method and FEM
Апстракт
In the paper the behavior of thin elastic metallic partially fixed plate produced by
electromagnet with constant flux is considered. Plate is simply supported along three edges and
fixed along the fourth one. As nonstationary electromagnetic field in one part of the plate varies
with time, conducting currents appear. Distribution of the power of eddy-current losses is obtained
by using complex calculation. The power of the volume heat source (Joule’s heat) depends of
permeability and conductivity of the plate and frequency of the alternative-current in
electromagnet. Characteristics of the electromagnet are described by using Pulsation, Heaviside
and similar functions. Differential equation governing temperature field is solved using by integral
transform technique. The mathematical form of the transversal vibrations is obtained in analytical
way using only simple finite Fourier transforms because the differential equation describing
transverse vibrations is adapted to for...m which enabling very easy simulation of the bending
moments along the fixed edges. Vibrations and stress in the middle surface of the plate are
calculated by using program package KOMIPS, based on the finite element method.
