Effects of Strand Lay Direction and Crossing Angle on Tribological Behavior of Winding Hoist Rope
Friction and wear behavior exists between hoisting ropes that are wound around the drums of a multi-layer winding hoist. It decreases the service life of ropes and threatens mine safety. In this research, a series of experiments were conducted using a self-made test rig to study the effects of the strand lay direction and crossing angle on the winding rope's tribological behavior. Results show ...

Continuing earlier investigations into the question cf the existence of a proper dense subgroup of a given topological group, the authors obtain some positive and some negative results, as follows: (a) Every non-degenerate connected Abelian group c...
متن کاملThe rope
We are aware that all information published by each issue of this journal needs the squeeze and sweat of thousands of people. On one end of the rope, researchers and higher education institutions work hard to produce science to the highest degree of excellence. On the other end, reviewers silently filter manuscripts, thus improving the quality and accuracy of information that has been approved....
