The technique is a kind of new concept of anti rolling ship at zero forward speed. It is different from conventional ship fin stabilizer that the lift of fin stabilizer based on movement mode of pitching and heaving is produced by initiative swing at zero speed. The lift control system is built according to lift feedback and lift limit. It is undoubtedly another development to introduce lift control...
It is different from conventional ship fin stabilizer that the lift of fin stabilizer is produced by initiative swing of movement mode of pitching and heaving at zero speed. For the fin stabilizer is belong to bigger inertia load, the reverse lift could be generated with the shorter braking time and the ship rolling would be acute and getting worse. So the lift limit element should be improved and...
The lift is not be generated on the wings when the water velocity is zero. So the conventional theory is not adapted to the anti rolling ship research at zero speed. And the technology of anti rolling ship at zero forward speed is a kind of new theory. In order to study the process of lift generation of fin stabilizer at zero speed, the model of lift generation of variable chord fin stabilizer is...
The edge detection for images based on traditional wavelet analysis has the disadvantage of not being sensitive to direction properties, so aimed at the problem the article makes some improvement and puts forward a new kind of wavelet transform used for image edge detection. Compared with the detection based on Canny operator, it can be concluded that the new kind of edge detection based on wavelet...
The method that fin stabilizer is used to anti rolling ship is different from the conventional theory of anti rolling ship, so it is a kind of new theoretics. In order to study the process of lift generation of fin stabilizer at zero speed, the model of lift generation of fin stabilizer is built based on biomimetic theory such as Weis-Fogh mechanism with variable chord wings by the conformal representation...
Ship fins stabilizer is a kind of anti rolling ship technique that the fins could produce lift with higher speed. Zero speed fins stabilizer run in the condition that ship is anchored or sailing at lower speed. Lift is produced by initiative swing of fins. The rolling forces of ocean waves could be counteracted by the lift and so the ship could be stabilized. For the lift measurement of zero speed...
