Abstract

Abstract:

According to the coupling relationship between the mechanical system and control system of scraper conveyor, the nonlinear state space electromechanical coupling equations were derived for scraper conveyor, the simulation model of the scraper conveyor was established by using MATLAB/Simulink module, the electromechanical coupling dynamics of the scraper conveyor system was studied, the equivalent load change of mass was used to analyse the scraper conveyor's scraper chain speed and electromagnetic torque characteristic curves in no-load start, stable operation, load surge and card chain condition.Two sprockets' angle curves were obtained at startup, the results show that, the start angle difference between drive sprocket and the driven sprocket is about 85°, the driven sprocket lag about 0.8s than that of drive sprocket when it rotates.It is provided the theoretical and numerical basis for studying scraper conveyor's torque,speed change and calculation of sprocket's pretension in different working conditions and loads.

Key words: scraper conveyor, electromechanical coupling, scraper chain speed, electromagnetic torque, angle

摘要：

根据刮板输送机机械系统与控制系统之间的耦合关系，推导出刮板输送机的非线性状态空间机电耦合方程，采用MATLAB/Simulink模块建立刮板输送机的仿真模型，对刮板输送机系统的机电耦合动力学问题进行仿真和研究；采用等效变化载荷质量分析刮板输送机在空载启动、平稳运行、载荷突增以及卡链工况下的刮板链速度、电磁转矩的特性曲线，得到了启动时两链轮的转角曲线。结果表明，驱动链轮与从动链轮启动时转角差约为85°，从动链轮启动旋转较驱动链轮滞后约0.8s。研究结果为研究刮板输送机不同工况、载荷下的转矩、速度变化以及计算链轮张紧度提供了理论和数值依据。
