Eksperymentalne wyznaczanie sił poprzecznych wywołanych skrętem suwnicy podczas jazdy

Stan suwnicy pomostowej zależy od dużej liczby zmiennych losowo zmieniających się w czasie. Ze względu na dużą liczbę parametrów, siły skośne mają charakter stochastyczny. Chociaż w normach traktowane są one jako obciążenia sporadyczne, ich dynamiczne oddziaływanie w niektórych przypadkach może powodować zmęczeniowe uszkodzenie mechanizmu jazdy suwnicy, jak również jego konstrukcji oraz elementów toru jezdnego. Obecnie obowiązujące normy europejskie pozostawiają bez rozwiązania kwestię wpływu sił skośnych na występowanie uszkodzeń zmęczeniowych. W pracy przedstawiono metodę eksperymentalnego wyznaczania sił poprzecznych działających na koła pionowe suwnicy pomostowej. Metoda ta polega na użyciu dwóch różnych rozwiązań przetworników do bezpośredniego pomiaru sił na kołach pracującej suwnicy, bez zmiany sposobu prowadzenia bocznego . Dla ilustracji pokazano kilka zapisów pomiarów siły poprzecznej koła w funkcji czasu. Przedstawienie takich zapisów w postaci widma obciążenia (np. za pomocą oprogramowania nCode ), uzyskanego podczas długotrwałego lub ciągłego monitorowania suwnicy w trakcie jej eksploatacji, stanowi pierwszy krok do znalezienia rozwiązania nierozwikłanego do tej pory problemu.

Experimental determination of lateral forces caused by bridge crane skewing during travelling

Crane condition depends on the large number of variables randomly changing in time. Due to the large number of parameters, skewing forces have stochastic character. Though in standards treated as occasional loads, their dynamic action in certain cases can cause fatigue damage of the crane travelling mechanisms, structure and runway components. Current European Norms have left the question of skewing forces influence upon the fatigue damage occurrence unresolved. The paper presents an experimental determination of lateral forces acting on the vertical wheels of a bridge crane using two different solutions of transducers for the direct measurement on the wheels of the cranes in operation, without changing the way of lateral guiding. As an illustration, few records of the measured wheel lateral force vs. time are shown. Presentation of such records in the form of a loading spectrum (e.g. using the software nCode), obtained during long-lasting or continuous monitoring of cranes in operation, is the first step in finding the relevant answer to the previously unresolved question.

The analysis of influential parameters on calibration and feeding accuracy of belt feeders

Continual material feeding represents a process of great importance for process industries. Feeding  with  belt  feeders  represents  one  of  the  most  common  methods. Belt feeders  are devices that require little space, they are not expensive and, most importantly, they do not interrupt material flow while feeding. Calibration of belt feeders, as well as other measur-ing devices, is a prerequisite for measuring and achieving a defined level of measurement accuracy. On the other hand, the defined level of measurement accuracy is often difficult to achieve in practice due to the multitude of factors that affect the operation of belt feeders. Existing mathematical models indicate a number of influential factors on measurement ac-curacy. The paper presents the measurement procedure performed on a belt feeder in labora-tory conditions, with variable speeds and belt tensions and the known raised position of the measuring idler. Based on the obtained results, appropriate conclusions were made about the influences on calibration and measurement accuracy
