Precise motion control remains one of the most important problems in modern technology. It
is especially difficult in the case of two-mass systems with flexible coupling if only the motor …

Blair mine hoists powered by drum winding are a key equipment in the transportation of a
superdeep mine shaft. The step changes of hoisting velocity and acceleration caused by coil …

In the mine hoisting system, the hoisting rope generates transverse–longitudinal–rotational
(TLR) motion due to external excitation and the structure of the hoisting rope. The motion …

Structural Safety aSSeSSment of Shaft Steelwork–a review shaft steelwork is a component
of critical infrastructure in underground mines. it connects the mining areas to the surface …

Mine hoisting systems have been widely used in coal mine industries. Due to a series of
uncertain faults in the steel guide, serious vibrations will be excited during the operation of …

We consider a two-mass drive with a flexible joint with a nonlinear characteristic of the
transmitted torque as a function of the torsion angle. We propose a new, nonlinear, adaptive …

An analytical solution is presented to the problem of determining the force effect of lifting
vessel (skip) on guides during its movement in the mine shaft. Forces values are obtained …

As an important equipment for deep well hoisting, the safe and stable operation of the Blair
mine hoist is vital for the development and utilization of deep mineral resources. However, it …

Due to the complexity of the interference operation environment of wire rope, the detection
signals are usually weak and coupled in time-frequency domain, which makes the defect …

It is difficult to implement modeling for overall construction due to the complex structure and
distinct environmental influences for the high-speed elevator so researchers rarely achieve …
