摘要: 针对圆管带式输送机头部双电动机驱动、尾部单电动机驱动的工况，考虑输送带黏弹性力学特征，以 Kelvin-Voigt模型为基础，在AMESim软件中建立了圆管带式输送机输送带-驱动滚筒部分离散模型；在三相异步电动机直接转矩控制基础上，研究了三电动机驱动系统功率平衡控制原理，提出了一种主电动机速度给定、2台从电动机转矩给定的圆管带式输送机启动控制方法；通过Matlab/Simulink仿真及圆管带式输送机综合试验台测试研究了基于该方法的圆管带式输送机启动过程，结果表明该方法可实现圆管带式输送机平稳启动，启动过程中头部主电动机与头尾部从电动机输出转矩基本相等，启动4 s后负载差值几乎为0。Abstract: For working status of pipe belt conveyor driven by two motors at head and one motor at tail, considering viscoelastic mechanics characteristics of conveyor belt, a discrete model for belt and driving drum of pipe belt conveyor was built in AMESim software based on Kelvin-Voigt model. Power balance control principle of three-motor driving system was researched on basis of direct torque control for three-phase asynchronous motor, and a starting control method of pipe belt conveyor was proposed which was based on speed given of master motor and torque given of two slave motors. Starting process of pipe belt conveyor based on the method was researched through Matlab/Simulink simulation and comprehensive test bed of pipe belt conveyor. The research results show that the method can realize stable starting of pipe belt conveyor, output torques of master motor at head and slave motors at head and tail are basically equal during staring process, and load differences are almost zero after starting for 4 s.
