Abstract

This paper presents a discretization procedure for the flexible
multibody modeling of reeving systems. Reeving systems are assumed to
include a set of rigid bodies connected by wire ropes using a set of
sheaves and reels. The method is capable to model the deformation of the
varying-length wire-rope spans. Wire ropes are assumed to deform
axially, transversally and in torsion. This paper shows the capability
of the presented method to model transverse vibrations. The
discretization procedure uses a combination of absolute position
coordinates, relative-transverse deformation coordinates and
longitudinal material coordinates. Each wire-rope span is modeled using a
single two-noded element under an arbitrary Lagrangian–Eulerian
approach. The discretization method is validated using analytical and
numerical reference solutions found in the literature that describe the
dynamics of varying-length strings. In addition, the dynamics of a
three-dimensional tower crane is simulated.
