[Abstract]:Bucket wheel stacker is a kind of continuous stowage machine commonly used in modern production. It has been widely used in loading and unloading of bulk materials such as wharf, metallurgy, power plant, steel plant and so on. The bucket wheel is the key equipment to realize its material collection in the bucket wheel stacker and the rational driving of the bucket wheel is very important to the bucket wheel machine. Direct drive volume control system has been developed rapidly in recent years and has been widely used in foreign countries. Compared with traditional valve control system and pump control system, direct drive volumetric control system has many advantages, such as energy saving, high efficiency and so on. Considering the advantages of direct-drive volumetric control system, this paper studies and designs the direct drive volumetric control system of bucket wheel according to the technical parameters of bucket wheel. In this paper, the hydraulic system of bucket wheel is designed, including the design of system schematic diagram and the design of related mechanical structure, in which the design of valve block also simplifies the structure of the system, and establishes the mathematical model of each link. The mathematical model of the direct drive volume control system of bucket wheel is obtained, the amplitude margin and phase margin of the system are made by PID control, the technical parameters of the system, such as frequency width, response speed and stability precision, are analyzed. The influence of the main parameters on the performance of the system is analyzed, and the computer simulation is carried out. Compared with DC motor, AC motor has the advantages of simple structure, reliable operation and convenient maintenance, and has been widely used in industrial production. In this design, the speed control of asynchronous motor is the key to realize motor speed control. In this paper, the AC asynchronous motor is controlled by variable frequency variable voltage control method, mathematical modeling and computer simulation are carried out, and then the vector control mode of AC motor is adopted and applied to the control of bucket wheel speed. The Simulink simulation model is built and the computer simulation research is carried out.
