Development of Research Methods for the Assessment of the Technical Condition of Ropes


Article Preview

Ropes, including steel wire ropes, are the essential component of the kinematic chains in many passenger and cargo transport systems. Their condition also determines the level of operational safety of those devices. The article is devoted to discussion of methods of assessing the condition of steel wire ropes. The paper discusses magnetic and visual methods. Both methods are used obligatorily to assess ropes employed in rope transport systems. The most significant advantages of the magnetic method and the capabilities of modern methods of analysis of signals obtained from such studies are described. An important part of this article is showing how to determine the geometrical parameters of ropes during a routine evaluation of the degree of wear. The second part of the article presents new methods of determining and recording the geometrical parameters of ropes based on vision systems. The original method of determination of those parameters described herein is complementary to the currently used methods of assessment of the wear of both steel wire ropes and the increasingly more common synthetic fibre ropes. The method is based on the analysis of vision signals. Images of rope surface are created using 3D technology. The article presents some results of research based on which it is possible to identify the geometric dimensions of ropes as well as defects on the surface of those ropes. Such identification is possible on a digital image of a projection of rope surface.
