船舶辅助设备用直线永磁电机的设计与优化OA

In the field of auxiliary equipment optimization,electromagnetic calculation,finite element mechanical analysis,and optimization algorithms are always adopted.This article applies numerical simulation and multi-objective genetic algorithm optimization methods for linear motors.Firstly,electromagnetic calculation and finite element mechanical analysis were used to design a linear motor structure which meets specific requirements.Subsequently,the impacts of parameters such as current density,effective motor width,and end dimensions on operational characteristics like magnetic pulling force and output thrust were studied.The most optimized structure,which achieves maximum output thrust under magnetic pulling force constraints and less thrust pulsation fluctuation,can thereby enhance linear motor performance and expand its application scenarios.
