提出一种由永磁同步电机和行星减速器组成的刮板输送机永磁半直驱系统。基于Adams和Matlab/Simulink搭建刮板输送机机械系统多体动力学模型和永磁半直驱控制系统模型，完成机电耦合系统的联合仿真。对刮板输送机空载、轻载和重载等多种工况进行仿真分析，得到各工况下永磁电机的输出特性和刮板输送机的动力学特性。研究结果表明:永磁半直驱系统能够实现低速大扭矩的快速输出，转速输出波动小，转矩输出具有良好的跟随性;永磁半直驱系统具有良好的启动性能和传动平稳性。刮板输送机机头转速、链环速度、链条张力在链轮多边形效应影响下呈周期性波动，受多边形效应影响链环在啮合过程中发生滑移，使得接触力呈波动变化，负载转矩和链条张力的波动随负载增大而加剧，随链轮转速增大而增大。
Research on electromechanical coupling characteristics of permanent magnet semi-direct drive system for scraper conveyor under complex working conditions
A permanent magnet semi-direct drive system composed of a permanent magnet synchronous motor and a planetary gear reducer was proposed for scraper conveyor.The multibody dynamic model of the scraper conveyor mechanical system and the permanent magnet semi-direct drive control system model were built based on Adams and Matlab/Simulink.Co-simulation of the electromechanical coupling system was completed.Various working conditions of scraper conveyor were analyzed,including no-load,light load and heavy load.The output characteristics of permanent magnet synchronous motor were gained.The dynamic characteristics of the scraper conveyor were obtained.The results show that the permanent magnet semi-direct drive system can achieve fast output of low speed and large torque,with small fluctuations in output rotation speed and good follow-up of output torque.The permanent magnet semi-direct drive system has good starting performance and transmission stability.Under the influence of polygonal effect,the rotation speed of the scraper conveyor head,the speed of the chain link and chain tension exhibit periodic fluctuations.The polygonal effect causes the slip of the chain link during the meshing process,resulting in fluctuating contact forces.The fluctuation of load torque and chain link tension intensifies with the increase of load and sprocket speed.
