曳引电梯磁流变制动装置的温度特性研究
Investigation on Temperature Properties of Elevator Magnetorheological Brake
摘要
Abstract
A new MR brake(MRB)was designed for traction elevator because of the shortcomings of the existing traction elevators with machine-electric brake—high operating impacts and high noise. The device had a dual-coil structure,which also designed channels for the circulation of coolant liquid for integral heat radiating,satisfying elevator braking with large braking torque and good heat dissipa-tion.Based on mathematical model in heat transfer,the numerical simulation analysis was performed for thermal field of MRB in no-load operation conditions and in typical emergency braking situation with finite element software.The work improved heat dissipation by using water cooling,revealing the temperature changing regularities under typical condition of key parts.The reasonable working temperature range was verified with test methods.Simulation and experimental results show that tem-perature has a greater impact on braking mechanics performance;however,the device can satisfy the requirements of the elevator operating with the effective cooling conditions.关键词
