摘要
本文在遗传算法基本原理的基础上,针对直线同步电动机的特点,建立了三维有限元数值分析与遗传算法相结合的电机优化设计模型,对电动机的直线推进力进行优化,为提高牵引系统中直线电动机运行的平稳性,论文在电机出力不变的前提下,对其谐波分量进行最小优化,并通过对具体实例的优化计算,表明遗传算法与有限元结合是电机优化设计领域中一种行之有效的全局优化方法。
Based on the fundamental theory of Genetic Algorithms(Gas) and the 3D Finite Element Method (FEM),this paper establishes a calculation model of the Linear Synchronous Motor(LSM) for optimizing the propulsion force.Keeping the output propulsion force,the design of the LSM is optimized and the harmonic content of the propulsion force get minimized.The results of the numerical calculation show that this method is effective and corrective in optimization design of the LSM.
