Dynamical Model for Determination of Horizontal Forces on Crane Runway during motion of the Crane

Popis výsledku v původním jazyce

During a motion of an overhead travelling crane on the crane runway horizontal forces between the crane and the crane runway girder occur. The reason of these forces can be the acceleration or deceleration of the crane and then most significant part of these horizontal forces is skewing of the crane. There are several methods for calculation of these forces. These methods depend mainly on computational model which is chosen. There were made some comparison of these methods in past conference by author of this article. The most significant load caused by motion of crane is the skewing. In the past the cause of the skewing was considered as the different speeds of the endcarriages of the crane which result to the horizontal transverse loads of the crane runway. In present the skewing of crane is defined as the motion of the overhead bridge crane with the constant velocity but with the angle relative to the crane runway. It means that the overhead bridge crane is angled relative to the crane runway and moves in constant velocity. During this motion the crane wheels are angled relative to the rail of the crane runway and the transverse forces occur on crane wheels. But this situation can occur also during the acceleration or deceleration of the crane. Present standards don´t take into account this situation. A dynamical model is presented in this paper which describes motion of the overhead double bridge crane during its acceleration. The dynamical model includes things which can influence the motion of the crane, the forces acting on crane wheels. The model thus describes the behaviour of the crane during acceleration in general and enables to determinate the horizontal transverse forces. The basic assumption of this model is that there is no contact between the rim of the crane wheel and the rail of the crane runway.
