The key matters of nonlinear finite element analysis are solved using verifications by mode tests simulating large surface ships and double hull tankers and nonlinear finite element analysis of ultimate strength of intact and damaged ships is performed.
Analytic hierarchy process (AHP),combining qualitative analysis with quantitative analysis,is apllied in the large-scale surface warship for optimization,involving multi-project and multi-object dicision-making.
It is considered that warship is exposed to non-contact underwater explosion loads when sailing on the sea and hull's overall responses of the warship subjected to the combination of bubble pulsation loads and wave loads in this paper. The purpose of this paper is investigating the overall strength of surface warship subjected to explicit loads including static bending moments, wave bending moments and bubble pulsation pressure.
Taking a surface ship for example, the three-dimensional calculation program is extended to engineering filed.
Based on a new and unique compilation of surface ship data over the world ocean, the Comprehensive Ocean-Atmosphere Data Set (COADS), the temperature records since 1870 were thoroughly analyzed.
To facilitate the interpretation of the results, a third estimate of the mean meridional circulation is produced by subsampling the reanalysis at the locations where radiosonde and surface ship data are available for the in situ calculation.
For a surface ship, the flow behind the propeller is influenced by the hull wake and the free surface.
For robust flight, surface ship or submarine control design, safety assessment, missile and aircraft guidance, the influence of disturbances, and differential games of pursuit-evasion, more versatile tools are needed.
