摘　　要：针对开槽型盘式磁力耦合器温升影响下的传动特性研究,以一台9对极16槽的开槽盘式磁力耦合器为研究对象,运用二维标量磁位法,建立磁力耦合器二维层模型,在考虑永磁磁场和感应磁场相互耦合的基础上,结合温度变化对永磁体剩磁的影响,推导盘式磁力耦合器的磁感应强度、输出转矩理论公式;通过有限元模拟分析,研究不同工作温度、不同气隙厚度下的磁场分布、输出转矩特性以及感应电流分布,并探究其变化规律;最后搭建试验平台测量耦合器的气隙磁场、输出转矩,对比分析其理论值与模拟值、试验值,验证理论模型的准确性,为研究考虑温升影响下开槽型盘式磁力耦合器的传动特性提供了理论依据。In order to study the transmission characteristics of slotted-type axial-flux magnetic coupler consideringthe the effect of temperature rise,a slotted-type magnetic coupler with 9 pairs of poles and 16 slots was researched.A two-dimensional layer model was established using two-dimensional scalar magnetic potential method,based on the mutual coupling of permanent magnetic field and induced magnetic field,the theoretical formula of magnetic induction intensity and torque were derived,combined with the effect of temperature changes on the residual magnetism of permanent magnets.Through finite element simulation analysis,the magnetic field distribution,output torque characteristics and induced current distribution under different operating temperatures and different air gap thicknesses were simulated,and their variation laws were explored.Finally,a test platform was built to measure the air gap magnetic field and torque.In order to verify the accuracy of the results obtained by the theoretical model are compared with those obtained by the simulation and the experiment,which provides a theoretical basis for studying the transmission characteristics of the slotted axial-flux magnetic coupling considering the effect of temperature rise.
