Contents

A numerical method of calculation of the eddycurrent induced within the system of parallel conducting bars of infinite length by a.c. flowing through these is presented. The integral equation approach is applied, which makes it possible to obtain an aproximate solution of the problem considered. As an example the eddy-current density within rectangular bars is calculated using digital computer.

Übersicht

In der Arbeit wird eine Methode zur Berechnung der Wirbelströme in parallelen und unendlichen langen unmagnetischen Leitern bei sinusförmiger Zeitabhängigkeit angegeben, u. zw. wird eine Integralgleichungsmethode angewandt. Als Beispiel werden die Wirbelströme in Leitern mit rechteckigen Querschnitten berechnet.
