Summary:The invention relates to a method for measuring parameters of a laminated iron core of a motor, in particular to a method for measuring anisotropic parameters of the laminated iron core based on modalanalysis. The defects and problems caused by only considering the modal vibration mode of the outer surface of the laminated iron core structure in the existing measurement methods are solved. The present invention is based on accurate test modal parameters, Using the benchmark comparison method of grouping optimization, the modal measurement of the laminated core structure is carried out comprehensively and precisely, the modal parameters are measured and identified, the modal parameters of the laminated core are obtained, Based on the characteristics of the real model, the equivalent modalanalysis of the finite element model of the laminated core structure as a transversely anisotropic homogeneous material with an internal tooth surface is carried out, and the sensitive parameters of the optimized finite elemen
