The use of thermal vision in testing the tension of steel ropes
Abstract
The article presents the results of experimental thermal imaging measurements of steel ropes as a basic structural element of handling and transport equipment. Based on the measurements, we can conclude that at an average value of the load of the tested ropes of 49.5%, the temperature in the critical point begins to rise significantly due to plastic deformation. When the set limit is exceeded in terms of Hooke's law, which expresses the relationship between the deformation of a solid body caused by the action of stress and the magnitude of this stress, plastic deformation (non-linear increase) occurs. Up to these values, the increase is linear and the deformation is directly proportional to the stress of the material. It is assumed that if the rope were damaged, the temperature could rise more sharply even with a smaller load on the rope. The presented results of the laboratory experiments and the course of the experiments themselves revealed the necessity of very accurate temperature targeting.
