- Abstract
In current studies for dynamic behaviors of the telescopic boom with thin-walled section in the aerial work platform, the model was simplified by ignoring the deformation of the cross-section. However, as the working length of the boom increases, the section deformation become larger under loading. For more accurate dynamic analysis, a one-dimensional dynamic model is developed for thin-walled octagonal cross-section boom considering the cross-section deformation in this paper. The model was established that the displacement field was formed through the linear superposition of a set of deformation modes. The deformation modes were defined based on the contour deformations of the cross-section, including out-plane and in-plane, resulted from the unit displacements on the discrete nodes. Then the deformation function between adjacent nodes was approximated with Hermite curve interpolation. The Hamilton’s principle was used to develop the governing equation, and further establish the corresponding finite element implementation. Finally, Specific example was also given to verify the accuracy in describing dynamic behaviors of thin-walled octagonal booms.
