Wire Rope Sheave Friction Effects
ثبت نشده
چکیده
When a takeup weight is offset to the side of a conveyor, a wire rope is commonly routed from the take-up weight through a series of sheaves to the take-up carriage. The friction developed from a series of wire rope sheaves can effect the actual belt tension at the take-up carriage. Through real-time testing the actual tension on a takeup carriage was recorded with data acquisition using an internally strain-gauged turnbuckle. The wire rope used to transfer the take-up weight to the take-up carriage was routed through a series of lubricated bronzed bushed sheaves. The tension on the takeup carriage was found to be as much as 26 % higher than the weight of the take-up due to the friction in the sheaves. A detailed discussion of the testing and results will be made.

Dynamic Contact between a Wire Rope and a Pulley Using Absolute Nodal Coordinate Formulation
Wire rope and pulley devices are used in various machines. To use these machines more safely, it is necessary to analyze the behavior of the contact between them. In this study, we represent a wire rope by a numerical model of a flexible body. This flexible body is expressed in the absolute nodal coordinate formulation (ANCF), and the model includes the normal contact force and the frictional f...
متن کاملModeling of multi-strand wire ropes subjected to axial tension and torsion loads
A new model characterizing the response of a multi-strand wire rope subjected to axial tension and axial torque is presented in this paper. Apart frommost of previous approaches which deal with a straight wire strand, the present model fully considers the double-helix structure in multi-strand configuration. To be further, a new method to compute local deformation parameters (two curvatures and...
متن کاملNon-Destructive Detection of Wire Rope Discontinuities from Residual Magnetic Field Images Using the Hilbert-Huang Transform and Compressed Sensing
Electromagnetic methods are commonly employed to detect wire rope discontinuities. However, determining the residual strength of wire rope based on the quantitative recognition of discontinuities remains problematic. We have designed a prototype device based on the residual magnetic field (RMF) of ferromagnetic materials, which overcomes the disadvantages associated with in-service inspections,...
