Dynamic responses of a gantry crane structure due to an accelerating moving mass
Апстракт
The dynamics of a two-dimensional gantry crane structure subjected to a
moving trolley with hoist and payload is examined. Dynamic responses of
structure, both in vertical (Y) and horizontal direction (X), are postulated
using the combined finite element and analytical method and solved with
the direct integration method. Instead of conventional moving force
problem, the two-dimensional inertial effects due to the overall mass of
trolley, hoist and payload have been considered in this paper. The title
problem was solved by calculating the forced vibration responses of the jib
crane structure with time-dependent overall mass and subjected to an
equivalent moving force. Factors as speed and acceleration of the moving
trolley were studied. Numerical results reveal that used approach is useful
and can draw conclusions for structural design purposes of gantry cranes
and approaches for creation of dynamic models.
