Title:
LAMINATED IRON CORE ELASTIC MATRIX DETERMINATION METHOD AND VIBRATION ANALYSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2020/095527
Kind Code:
A1
Abstract:
Provided are a laminated iron core elastic matrix determination method and vibration analysis method with which it is possible to optimally determine a modulus of transverse elasticity in two planes including the lamination direction of a laminated iron core, said modulus of transverse elasticity being included in the elastic matrix in a constitutive equation that is used for vibration analysis and that represents a relationship between stress and strain. When a constitutive equation representing a relationship between stress and strain in a matrix representation is used to perform vibration analysis on a laminated iron core (21) obtained by laminating steel plates (22) together, a modulus of transverse elasticity in two planes including the lamination direction of the laminated iron core (21) is determined in accordance with the average clamping pressure in the lamination direction of the laminated iron core (21), said modulus of transverse elasticity being included in the elastic matrix in the constitutive equation.
