摘　　要：针对电梯载荷试验替载装置组合加载过程中对磁粉制动器性能研究的不足,文中提出对磁粉制动器加载性能进行试验研究。搭建基于三相异步电机试验平台,对磁粉制动器的加载响应时间、输出扭矩等进行性能试验,试验结果分析得到:磁粉制动器加载响应存在一定的滞后性,加载响应时间为12.5 s,电机转速对磁粉制动器加载响应时间没有影响;磁粉制动器的控制电压在0.3～1.3 V范围内,其输入电压和输出扭矩呈线性关系;当磁粉制动器的控制信号一定时,电机转速越大,磁粉制动器的输出扭矩越稳定。试验研究结果为磁粉制动器应用在电梯载荷试验替载装置中提供了试验依据。In view of the lack of research on the performance of magnetic powder brake in the process of combined loading of load test of elevator load test,the loading performance of magnetic powder brake was studied.Based on the three-phase asynchronous motor test platform,the performance test of the magnetic powder brake loading response time and output torque was carried out.The analysis of the test results was:There was a certain hysteresis in the loading response of the magnetic powder brake.The loading response time was 12.5 s,and the speed of the motor has no effect on the loading response time of the magnetic powder brake.The control voltage of the magnetic powder brake was in the range of 0.3~1.3 V,the input voltage and the output torque are linear.When the control signal of the magnetic powder brake was certain,the greater the speed of the motor,the more stable the output torque of the magnetic powder brake.The experimental results provide the experimental basis for the application of magnetic powder brake in the load replacement device of elevator load test.
