METHOD FOR OPTIMIZING STRUCTURED MESH GENERATION FOR A THERMAL ANALYSIS MODEL OF A ROTOR BAR OF AN AC MOTOR

摘要

Provided is a method for optimizing structured mesh generation for a thermal analysis model of a rotor bar of an AC motor. A quadrilateral is randomly added within the top surface of the thermal analysis model of the rotor bar. The polygonal top surface is divided into multiple quadrilateral areas by drawing lines from each vertex of the quadrilateral to each vertex of the top surface or two points selected randomly on each edge of the top surface, respectively. A fruit fly optimization algorithm is adopted to obtain a maximum value of the average quality of the quadrilateral areas in a division mode and corresponding coordinates of the vertices of the quadrilateral areas. The top surface is divided into multiple quadrilateral areas according to the division mode corresponding to the maximum average quality to divide the model of the rotor bar into multiple columnar models.
