Generally computer simulations are used to gain insight into the dynamical
behaviour of cranes. This report describes the results of an experiment done
with a multi-body programme called "Adams".
The experiment investigates the vibrations of a container gantry crane, in the
direction perpendicular to the quay. When the vibrations of a crane become too
large, they can interfere with the normal operation of the crane. Vibrations
can for instance cause difficulties in positioning the load. In order to
create correct simulations a simplified model of a container gantry crane
was first made. This model was translated to the computer programme, Adams.
By varying several parameters of the model, important characteristics of the
crane can be changed. The results were gathered by simulating different speed
and acceleration patterns of the trolley, and monitoring the vibrations of the
crane. The results have shown that with certain combinations of
characteristical vibration frequencies, disturbing resonances can occur.
