EXPERIMENTAL STUDY OF SPRINGING VIBRATION IN SHIPS

An experimental study of the stresses caused by springing vibration and associated fatigue damage on the structure of an 18,000 dwt tanker is described. The study was conducted during a typical trip of the tanker along the Brazil coast. Signals from strain gages and acceleration transducers installed aboard the ship were recorded and processed in a spectrum analyzer to get the amplitude spectrum response. In a second stage, the stress concentration factor was estimated for selected locations on the ship structure. Measured stresses were used to assess the fatigue damage based on SN curves for typical ship joints.
