摘　　要：带式输送机需要采用动态分析方法进行精确设计。本文选择适用于输送带的粘弹性动力学模型,开发了具有闭环控制的驱动装置仿真模块,电动机的输出扭矩和转速随负载力矩和时间而变化。对整个输送机系统应用仿真软件建立了动力学仿真模型,采用PID控制器对输送机启动过程进行控制,构造闭环控制系统,对带式输送机的动态特性进行分析,从而为输送机启动的分析和控制以及系统的优化设计提供精确的分析手段。With the development of belt conveyor dynamical analysis was required to design conveyor.The viscoelasticity model suiting to the belt was selected,and simulation model of driving device with closed-loop controlling was developed,which indicated that motor speed and its output torque vary with load and time,therefore the simulation results were more close to practice.The dynamic simulation model of overall conveyor system was programmed,and PID controller was applied to stabilize starting process of conveyor,thus the closed-loop controlling system was created in simulation software.The simulation of dynamic performances of conveyor provided accurate design techniques to controlling starting process and optimizing on belts system.
