Belt conveyor has become a combination of mechanical,electrical,hydraulic and control and other disciplines as one of the bulk of the modern large-scale continuous transport equipment,one of its continuous to the high speed,long distance,large volume and high power The development of the direction of the belt conveyor to the dynamic characteristics of its performance has become increasingly prominent.The tensioning device of the belt conveyor is one of the important components,which has important influence on the dynamic characteristics of the belt conveyor,which is related to the safe operation and service life of the belt conveyor.Therefore,it is important to study the tensioning device of belt conveyors(especially large belt conveyors).In this paper,a new hydraulic tensioning device is obtained by improving the hydraulic tensioning device of the traditional belt conveyor.The working principle of the hydraulic tensioning device is introduced.The dynamic model is used to analyze the physical model of the tensioning device Using the whole model analysis,the mathematical model of the components in each module is established,and finally the mathematical model of each module is integrated to get the mathematical model of the tensioning device.The PID control method is selected in the electrical control,and an improved particle swarm optimization algorithm is obtained on the basis of the standard particle swarm optimization algorithm.The simulation results show that the improved particle swarm optimization algorithm Which is better than the standard particle swarm optimization algorithm.And then through the improved particle swarm optimization algorithm to optimize the three parameters Kp,Ki,Kd in the PID controller,a set of data is obtained.The mathematical model of the optimized PID and hydraulic tensioning device in the Simulink module of Matlab The results show that the step response of the former is less than that of the latter.The results show that the step response of the former is less than that of the non-optimized PID and hydraulic tensioning device.After simulating the Simulink simulation software with MATLAB,it is possible to verify that the dynamic performance of the optimized hydraulic tensioner is better.So that the hydraulic tensioning device in the PID control under the belt conveyor running a variety of conditions have a good response speed,the control of the tension can be more accurate,so that it can be completed in a short period of time tight band And the loose belt,but also to the conveyor belt by the impact of small operation to cause less vibration,to achieve better control results.
