Abstract

The acceleration changes during the rope circle transition of multi-layer winding in super deep mine hoist was studied. Using lifting wire rope dynamic tension differential equation and the MATLAB Simulink module to establish symmetric and non symmetric bilinear transitional rope slot multi-layer winding wire rope dynamic tension simulation model and the simulation results are analyzed and compared. The results show that The acceleration of the rope circle transition of the multi-layer winding wire rope will have a significant impact on the dynamic tension of the wire rope. It is obvious that the dynamic tension of the circle transition in symmetrical bilinear rope groove is larger than that of the non symmetrical bilinear rope groove. These results have important reference value for the study of multi-layer winding of the super deep well lifting system.

Key words
