The Method of the Coal Mining Machine Height Control Based on Magneto-Rheological Tactile Reappearance

Abstract:

Article Preview

Through analyzing height character of the coal mining machine, the method of height control of the coal mining machine based on touch sensing technology of magneto-rheological valve is proposed. The controller exports control signal based on extracting current and speed signals of shearer cutting motor and controls touch sensing force feedback based on magneto-rheological valve. The operator can accurate and duly adjust roller height of the coal mining machine. The result of simulations and experiments show that the method is important to avoid the coal mining machine cutting the roof and floor rock and maintain the roof and floor of the formation face, and extend machine life, improve equipment reliability, protect worker safety, improve coal quality. This structure of control method is simple and easy to achieve which has a certain application foreground.
