Computer aided analysis of a plate subjected to a circular moving load

Moving load problem is investigated by engineers in various engineering structures such as beams and plates. In this thesis, vibration analyses of plates subjected to a circular moving load are realized by using the finite element method. ANSYS parametric design language is used to create the finite element model of the plate considering circular trajectory. A single point load is moved over the circular trajectory. The amplitude of the circular moving load changes harmonically on the plate. The two excitation frequencies corresponding to the first two natural frequencies of the plate are used in the harmonic circular moving load. The dynamic time response is obtained from the middle point of the plate. Natural frequencies of the plate are found with the modal analysis. The results are compared with the reference study. The effects of the radius of the circular path, forcing frequency and rotating speed of the moving load are investigated.
