Abstract

U teoretskom dijelu rada opisana je primjena čeličih užadi, vrste opterećenja koje djeluju na njih te sama primjena čeličnih užadi. Čelično uže je savitljivo uže, sastavljeno od više čeličnih žica, velike čvrstoće jednostruko ili dvostruko opletenih oko jezgre užeta. Mjerni instrumenti koji se koriste za mjerenje deformacija i naprezanja čeličnih užadi nazivaju se tenzometri. U eksperimentalnom dijelu rada vrši se umjeravanje tenzometra pomoću dvije poznate metode. Prva metoda je metoda pomoću mjernih utega, a druga metoda pomoću elastičnog mjernog uređaja. Svaka od ove dvije metode koristi specifičnu opremu za umjeravanje, a sam postupak umjeravanja je jednostavan. Na samom kraju rada provedena je obrada i analiza rezultata te su doneseni određeni zaključci.

Abstract (english)

In the theoretical part of this study is described application of steel ropes, types of overtures that act on it and application of steel ropes. The steel rope is flexible rope made of multiple wire of high strength which are single or double wrapped around the rope core. The measuring instruments used to measure deformation ond strain of steel ropes are called tensometers. In the experimental part of this study, calibration is perormed using two known methods. The first method using metering weight, and the other method using an elastic measuring device. Each of these two methods uses specific calibration equipment and the calibration procedure is simple. In the end, the processing and analysis of the results were carried out and certain conclusions were drawn.
