A series of stiffened panels with different dimensions and types stiffener are simulated under longitudinal compression in finite element code ANSYS. Two bays/spans model periodic boundary condition is adopted to consider the influence neighbouring members. The panel mode generally cut from deck or bottom a ship hull girder, thus, constraint on their edges depends some extent relative structural response adjacent Hence, understand effects collapse behaviour, an extensive parametric study...
Array signal simulation of active sonar echo is an important basis for the verification new target detection technologies and equipment training. Backscatter main part monostatic target. Based on improvement traditional highlight model submarine target, this paper presents a method to simulate backscatter based spatial distribution characteristics intensity at different angle ship's side. Compared with method, signals obtained by proposed can better reflect broadening amplitude fluctuation...
abstract:Remote sensing technology is playing anincreasingly important role in the investigation and exploration of oil gasresources. Using thermal infrared remote to detect offshoreoil gas resources one new methods, but there are many uncertainties. Inthis paper, MODIS data used explore availabilityin North Yellow Sea Basinthrough extracting temperature anomaly areas. Result shows that this methodcan be effective assisting exploring undersea resources.
This paper illustrates the experimental study on glued bamboo beam. The beams are characterized by brittle tensile damage. elastic modulus for both compression and tension of equal to each other. average strain cross-section beam is linear distribution during test process. Thus plane assumption can be used calculating when designing. All deflections ultimate load point more than 60 mm far bigger value 8.4mm (L/250) which maximum allowable deflection required Chinese wood structure design...
It is vital to investigate the situations of ship bottom under longitudinal compressive load that results from bending hull girder, and at same time considering effect lateral pressure. The periodical boundary conditions for two spans model are adopted analyse collapse behaviours stiffened panels combined axial thrust material geometric nonlinearities considered in simulation. pressure affect significantly on panels, which relate with dimensions stiffeners plates.
Nonlinear finite element analysis is usually used to assess the ultimate strength of hull girder, which includes implicit and explicit dynamic analysis. So far, most researchers use various vessels or stiffened plates. Comparing with analysis, may be more stable since this method doesn’t need consider convergence solution, can transient influence time. However, accuracy solution results time in very important. This depends on modelling configurations, such as loading time, geometric ranges...
