comparison of the continuous model and the finite element model of the gantry crane carrying structure for modal analysis

Introduction/purpose: to study the adequacy of applying numerical methods in the modal analysis of complex carrying structures of cranes. methods: comparative application of the analytical method and the numerical method - fem. results: some comparative values of the modal parameters were obtained both analytically and numerically for the derived solution of a gantry crane carrying structure. conclusion: it is shown that the numerical method can give a reliable general quality estimate of the structural behaviour of a complex carrying structure from the aspect of modal analysis.
