FORCES ON A CYLINDER OSCILLATING SINUSOIDALLY IN WATER

Deals with the experimental modeling of wave forces on offshore structures. The model chosen is a sinusoidally oscillating cylinder in a body of water otherwise at rest. This model represents a sinusoidal progressive wave moving past a single, fixed leg of a platform. The dynamic force generated by the water-cylinder interaction was measured by means of strain gages. Oscillations of amplitudes ranging from 0.67 to 9.6 cylinder diameters and frequencies from 10 to 60 cpm were covered in the investigation. Results are presented in the form of diagrams of force vs velocity with acceleration as a parameter and of maximum force vs the amplitude parameter, A/d.
