DYNAMIC ANALYSIS OF A SINGLE POINT, TAUT, COMPOUND MOORING

An analysis of motion in a taut compound mooring is presented. A model is proposed consisting of a series of discrete masses connected with linear springs. Motion is assumed to be one-dimensional along the longitudinal axis of the model. The analysis predicts the natural frequencies of the model without damping or external forces. These results are used as a basis for analyzing motion of the masses and tensions in the springs when the model is driven with an external force where damping, from tangential drag, is assumed to be proportional to velocity squared. Solutions are obtained by computer programmed numerical techniques. Both steady state and transient cases are studied. Response of the system with alternations of drag and spring stiffness is also studied. (Author)
