ELASTICITY MATRIX DETERMINATION METHOD AND VIBRATION ANALYSIS METHOD FOR LAMINATED IRON CORE

摘要

Provided are an elastic matrix determination method and a vibration analysis method for a laminated iron core, with which it is possible to optimally determine an elastic modulus of a laminated iron core. When a vibration analysis of a laminated iron core (21) obtained by laminating steel sheets (22) is performed by using a configuration expression indicating a relationship between stress and strain in a matrix display by using an elastic matrix, a shear modulus in two surfaces including a laminating direction of the laminated iron core (21) included in the elastic matrix in the configuration expression is determined in consideration of slip between laminated steel sheets (22).
