Abstract

The finite element method (FEM) which is popular in calculating strength of engineering constructions disposes a long list of basic finite elements (FEs) for building discrete finite element design dynamic models (DDMs) of lifting cranes. The paper presents the general methods of developing equations of motion for crane systems with multiple (n) degrees of freedom and their components in the form of matrixes of stiffness and masses of a thin-walled bar and plate FEs, the latter being analyzed using the Kirchhoff plate theory. The produced final formulas help to analyze the quality of DDM of structural steelworks of the bridge cranes built using bar FEs with a closed profile and plate FEs based on the comparison of general bending stiffness of longitudinal girders and on the comparison of fundamental frequencies (FFs) and eigenforms (EFs) of oscillations of their DDM.
