摘　　要：磁力驱动设备具有静密封、过载保护、环保等优点,其应用越来越广泛。永磁体间的磁力和磁力矩是磁力驱动技术研究的核心问题。目前,有很多研究聚焦于建立3自由度或4自由度解析模型求解磁力矩,其应用都具有一定的局限性。为此,基于等效磁荷理论,建立环形磁体之间的5自由度磁力矩解析模型,分析了相对位移、偏心及角度等因素对磁力矩的影响规律。该模型能够求解两个轴向磁化的环形磁体处于任意相对位置和姿态时的磁力矩。研究方法为磁力驱动设备的研究与应用提供了借鉴。The magnetic drive equipment has advantages such as static sealing,overload protection and environmental friendliness,and its application is becoming increasingly widespread.Magnetic forces and torques between permanent magnets are the focus of the research on the magnetic drive technology.At present,many studies focus on establishing analytical models with three or four degrees of freedom to solve magnetic torques,but their applications have certain limitations.Based on the theory of the equivalent magnetic charge,a five degrees of freedom magnetic torque analytical model was established between circular magnets,and the influences of factors such as relative displacement,eccentricity,and angle on the magnetic torque were analyzed.This model can solve magnetic torques of two axially magnetized magnetic tubes at any relative position and posture.This study provides reference for the research and application of the magnetic drive equipment.
