In order to qualify the anti-shock performance of shipboard equipment and simulation actual underwater explosion(UNDEX) environment, a novel dual-wave shock test machine is developed. This machine is based on the concept of hydraulic drive system and it can generate a dual-wave shock acceleration meeting the specification defined in BV043/85. This paper establishes the simulation model of the hydraulic-actuate...
Ship fins stabilizer is a kind of anti rolling ship technique that could produce lift with initiative swing of fins at zero forward speed, and the lift could counteract the rolling forces of ocean waves. The method that fin stabilizer is used to anti rolling ship is different from the conventional theory of anti rolling ship at zero speed, so it's a kind of new theoretics. In order to study the process...
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 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...
