Theoretical and experimental study of process of a bridge crane movement

Abstract

The process of crane movement accompanied by significant losses of energy, increased
stress on the elements of the structure and mechanisms, as well as on crane structures. Currently,
various practical measures compensating for negative phenomena (anti-skew motion control
systems, refined wheel alignment and alignment of track) are spreading. However, assessments of
the applicability and effectiveness of these measures are limited by the absence of the necessary
theoretical and experimental justification. The main constraining factors are the multifactority and
interdependence of processes, as well as the problematic nature of performing full-scale
measurements in the required volume with the required accuracy. In the paper, the relevant
problems are consistently considered and ways of their solution are proposed with the involvement
of new tools, first of all, information technologies. The mathematical model provides not only
calculations, but also operations specific to the database. The experiment is carried out with an
elastic model, which has special areas with increased sensitivity to lateral loads. It is possible to
change the wheel alignment angles and the shape of the track. The received data are analyzed with
the help of computer facilities. The results of the experiment are used to verify the correctness of
the mathematical model, which can later be used to calculate actual cranes.
