摘要

Aiming at the influence and future control tactics of its supply frequency on performance of steel‐climbing ro‐bot platform on basis of Single‐Sided Linear Induction Motor, this paper simulates and calculates the supply frequency of LIM by way of finite element method Ansoft, discusses the out thrust, normal force, flux density on different parameters and the current density of the secondary back‐icon, and calculates the relation between frequency and power factor of this mo‐tor .The result proves the rationality and feasibility of the model machine design, and provides a theoretical reference for the next optimization design of the model machine .%针对基于单边直线感应电机（SLIM ）原理制成的钢板爬壁机器人平台，为了研究其供电频率对性能的影响及下一步的控制策略，本文使用Ansoft有限元分析法对直线感应电机供电频率进行了仿真计算，探讨了电机的推力，法向力，不同部位磁通密度以及次级铁心电流密度随之改变的幅度和规律，并结合M atlab计算了电机频率与功率因数的关系，得到了合理的结果，验证了样机设计的合理性和可行性，为下一步样机的优化设计提供了理论参考。
