摘要：Enlargement of containerships during this decade has brought about imminent concerns on ship’s dynamic elastic response and its influence on ultimate and fatigue strength of hull structures. The authors reviewed literatures on this topic, identified problems to be solved, and firstly developed a dynamic elastic response analysis system comprising ship motion analysis based on Rankine source method and 3D finite element analysis based on newmark- β method, enabling simulation of hull stresses including dynamic elastic components. Comparison of calculated results and model test results was carried out both in regular and irregular waves. It was confirmed that this system can simulate ship motions, hydrodynamic pressure and vertical bending moment including dynamic elastic response with sufficient accuracy. Based on the achievements, future tasks were identified as expansion of the applicable scope of the system, further verification of calculation accuracy including comparison with full scale measurement, parametric studies of the effect of various parameters on dynamic elastic response, and rational generation of design irregular waves.
