This paper describes the dynamic behavior of the suspended cable subjected to the periodic excitation. The periodic excitation at the end of cable causes the parametric excitation on the suspended cable. The governing equation is formulated by the absolute nodal coordinate formulation to evaluate the effect of the deformation of the flexible cable on the dynamic behavior. The effect of elongation of cable on the restoring force is evaluated by the numerical simulation. The result of the simulation indicates that the elongation of cable is very small. This result shows that the gravity force has a dominant effect on the restoring force of the suspended cable. The validity of proposed method is verified through the experiment. In the experiment, the dynamic behavior of the suspended cable is analyzed by the image analysis with the high-speed camera. The numerical simulation results are in good agreement with the experiment.
