Diagnostyka lin stalowych stanowiących elementy konstrukcyjne obiektów budowlanych

Abstract: Zastosowanie lin stalowych w budownictwie obejmuje między innymi cięgna i stężenia w konstrukcjach stalowych. Diagnostyka lin stalowych to głównie nieniszczące badania defektoskopowe zorientowane na wykrycie pęknięć drutów, deformacji, starć oraz korozji. Jako metody badań stosowane są najczęściej różnego rodzaju metody magnetyczne (aktywne i coraz częściej pasywne) oraz wizualne. W artykule przedstawiono charakterystykę stosowanych metod oraz wyniki diagnostyki lin stalowych na przykładzie wybranych realizacj… Show more

“…Hall sensors are widely used in MTR magnetic inspection to detect the changes in reluctance of magnetic circuits (detecting corrosion and continuous losses of the rope cross-section. The measuring bandwidth of MI sensor ranges from 0 to 1 MHz, depending on the specific requirements for the given application: scanning rate, resolution, signal-to-noise ratio SNR (Kwaśniewski et al, 2017). MPM measurements of compacted ropes (Bridon Tiger Brand Dyform 34LR, F42 mm 34(w)xk7-wsczZ B(Zn), according EN 12386-2, seven years of work, number of cycles 50000-52000) operated in the shaft Bzie 1 rely on a matrix array 2×16 of three-axis Magneto-Impedance sensors (digital compasses) arranged in the vertical line about 12 mm from the wire rope, with resolution 0.6 μT and parallel sampling (Fig.…”

“…New advances in modelling and applications of magnetic materials in magnetic circuit components further the research work in the field of materials and electrical engineering. It is difficult to pinpoint those areas of engineering expertise which do not make use of magnetic materials, that also applies to the active MTR method (magnetic testing of wire ropes) which relies on external magnetic fields (Kwaśniewski, 2010). Passive methods of wire rope inspection utilise the magnetic fields of those structures to detect the magnetic anomalies with the use of high-sensitivity magnetic sensors, including those based on amorphous materials.…”
