  In recent years, it has been strongly required to reduce radiated noises from transformer cores used in electric power systems. The noises from transformer cores seem to be mainly caused by magnetostriction. Thus, it is necessary to establish a method for quantitatively calculating the force generated from the magnetostriction (magnetostriction force) with not only high-accuracy but also high-speed. This paper presents that the magnetostriction force is calculated based on a reluctance network analysis (RNA) by using a simple-shape wound core as an object of discussion. The validity of the proposed method is indicated by comparing with calculation results obtained from a finite element method (FEM).
