碩士 / 國立成功大學 / 水利及海洋工程學系 / 78 / A numerical model is developed in this study as a design tool for ocean buoy system. and in particular, to predict the responses of a data buoy. the simulated responses transfer function of data buoy may then be used to calcualte the ocean wave characteristics.
Morison Equation and Lumped Parameter Method are employed to establish the equations of motion for a buoy/single point mooring system under the envionmental loaditigs of wind. wave and current combined. The time domain responses of each lumped mass for the buoy system are calculated by explicit second-order predictor-corrector integration method. Numerical analysis consists of determining the tether tension and the surge. heave and pitch buoy responses.
Labortory experiments are conducted to determin various physical parameters and hydrodynamic coefficients of buoy. and to validate the numerical simulations. These include heave and pitch impulse tests. Hydrodynamic coefficients and material properties of moorings are obtained from the previous study of Nath (1977).
The dimensionless tether tensions and the buoy motions in various wave and current conditions are studied systematically. Parametric studies are then conducted to evaluate the effects of dimensionless wave length on the heave transfer functions for buoy.
