STRESS AND DEFORMATION STATES ANALYSIS OF VERTICAL SHEET METALS ON BOX-SHAPED GIRDER
In this paper, an engineering (stress deformation) analysis of several different models of the main crane bridge carrier with box-shaped cross section on which the rail is located above one of the vertical sheet metals is performed. Stresses and deformations of the vertical sheet metals were analyzed depending on their mutual distance and the thickness of the strap sheet metals. The task was to get the appropriate mutual dependencies of vertical sheet metals stress states. The results could be used afterwards for defining boundary conditions when optimizing the carrier with the box-shaped cross section (i.e. optimization using nonlinear programming with constraints). This could be one of possible ways for the dimensioning of carriers that would be lighter than the existing ones of the same material with equal working conditions. For the analysis CAD / CAE (Computer Aided Design / Computer Aided Engineering) software CATIA V5 has been used.
