Bezpal'ko T. Planning parameters for optimizing rope capacity of mining hoist cylinders

This thesis presents the technique for optimizing the rope capacity of hoist cylinder surface parameters. Enhanced models of rope winding on the profiled surface of hoist cylinder were constructed and their adequacy was demonstrated. The analytical dependencies were determined for the set of parameters and constraints of the profiled surface of a cylinder with (1) the length of the zone of contact of the wound rope with its neighboring coil, (2) the crookedness of the rope axis, and (3) the parameters of its laying into the groove. Optimal values for these parameters were obtained according to the projected rope capacity parameters of the profiled surface of the cylinder. Methodical recommendations for the choice of optimal parameters for the profiled surface of mining hoist cylinders were developed and introduced.
