Research on Driving Characteristics of Virtual Prototype of Belt Conveyor
With the development of the belt conveyor towards long distance and high speed,It is very important to study its dynam-ic characteristics.The complex driving characteristics of belt conveyor were studied.It was ideal to simplify the load torque to a con-stant value.But it neglected that the motor speed and torque change in real time with the load torque.To solve this problem,firstly,the dynamics model of heavy hammer belt conveyor was established based on Voigt belt model in RecurDyn;secondly,the vector control model of induction motor was established by Simulink;Finally,the motor drove the conveyor,and the load torque output of the conveyor was returned to the motor by using the multi-domain collaborative simulation strategy,so as to form a closed-loop control to make it start to stable operation and analyze its current and dynamic characteristics.The research results show that the output flux and speed of the motor can reach the expected value,and the relative error is 0.01% and 1.29%,respectively,so that the start-up of the belt conveyor can be accurately controlled,and the operation law is proved to be in line with the actual operation conditions,which provides an effective research method and basis for the electromechanical system design of belt conveyor.
