Abstract


Development can not be separated from marine engineering equipment , crane ship is essential for marine construction engineering ship Nonlinear Dynamic Analysis of the mooring system crane ship Nonlinear Studies Based on the analysis the anchor cable dynamics analysis of the status quo on the basis of the rope has been conducted static and dynamic analysis . Static analysis is the basis of the analysis of the power use of two methods for static analysis of the anchor cable , first of all , the use of the cable catenary equation for a single component and multi-component anchor cable static analysis ; Second, the use of finite element method, a the anchor cable geometrically nonlinear rod element finite element model , the use of quasi-Newton method Anchor static problem solved numerically ; consider the finite element model of large displacements and small strains of the anchor cable , by the non- linear fluid resistance , wave force, gravity and boundary conditions , static analysis , has been the anchor cable static equilibrium position , the tension of the anchor cable . Dynamic analysis , the anchor cable slight vibration in the vicinity of the static equilibrium position as the linear vibration problems , we use the formation superposition dynamic analysis of the rope has been conducted , has been the natural frequencies of the anchor cable , each order modal , anchor sinusoidal excitation power response ; consider currents , wave nonlinear mooring system based on the use of the principle of virtual work , the establishment of the anchor kinetic equation , Wilson - theta method , in the time domain integral kinetic equation is solved, and the nonlinear dynamic response of the anchor cable . In order to verify this article the cable static and dynamic analysis of a variety of methods , the use of matlab prepared the cable static and dynamic analysis procedures , and examples for static and dynamic analysis of a plane anchor cable for analog mooring system the nonlinear interaction of the ship , we design the mooring system of the experimental simulation device to simulate the actual ship model experiment carried out in tanks , mooring system .
