摘　　要：设计了一种具有双线圈结构的磁流变制动装置,该结构满足曳引电梯较大制动力矩和良好散热功能的要求。基于数学物理方法,在COMSOL Multi-physic有限元软件中建立了曳引电梯磁流变制动装置多物理场模型,即静磁场、流场与转子动力学方程相互耦合的数学模型,利用该模型进行动态仿真研究分析,揭示不同电流、转速下磁流变制动装置的制动力矩、制动时间、温度的变化规律和动态性能。最后进行了实验验证,仿真分析结果与试验结果相吻合。A MRB with dual-coil structures was designed. The requirements of elevators with large braking torques and good heat dissipation were met by the structures. Based on the mathematical physics method, the multi-physics model of elevator MRB was established in COMSOL Multi-physic finite element software, namely the static magnetic field, flow field and rotor dynamics equation, the mathematical model of coupled to each other. The model was used to research dynamic simulation, the braking torque, braking time, temperature changes and dynamic performance of the magneto-rheological braking device under different current and rotational speed were revealed. Finally, experimental verification was carried out, the simulation results were consistent with the experimental ones.
