    摘要:

    帶式輸送機需要采用動態(tài)分析方法進行精確設計。本文選擇適用于輸送帶的粘彈性動力學模型,,開發(fā)了具有閉環(huán)控制的驅(qū)動裝置仿真模塊,,電動機的輸出扭矩和轉速隨負載力矩和時間而變化,。對整個輸送機系統(tǒng)應用仿真軟件建立了動力學仿真模型,,采用PID控制器對輸送機啟動過程進行控制,,構造閉環(huán)控制系統(tǒng),,對帶式輸送機的動態(tài)特性進行分析,,從而為輸送機啟動的分析和控制以及系統(tǒng)的優(yōu)化設計提供精確的分析手段。

    Abstract:

    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.
