Problems solved by technology

[0003] The traditional damage stability calculation and model test schemes are mainly based on the transverse wave state of the ship. The model test is generally based on two methods: one way is to assume that the damaged compartment has been completely flooded, and at this time it is considered that the ship has lost a certain buoyancy. The first method is based on the quasi-static method,

Embodiment Construction

[0017] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0018] Such as Figure 1-2 As shown, the active control device for ship damage stability model test of this embodiment includes a hull model 10 and a driving mechanism, the side of the hull model 10 is inlaid with a transparent organic window panel 20, and a damage opening is provided in the transparent organic window panel 20. 21. A magnetic steel frame 30 is adhered to the outer end surface around the damaged opening 21. The damaged opening 21 is covered with a magnetic cover plate 40. The magnetic cover plate 40 and the magnetic steel frame 30 attract each other. The driving mechanism pulls the magnetic cover plate 40 to move so that The breach 21 is opened. Wherein the transparent organic window plate 20 is made of organic glass.

[0019] The driving mechanism comprises a mounting plate 51, a motor 52, a rotating shaft 53, more than ...

Abstract

The invention relates to the technical field of ship damage stability model tests, in particular to an active control device for ship damage stability model tests, which comprises a ship body model and a driving mechanism, a transparent organic window plate is embedded in the broadside of the ship body model, a damage opening is formed in the transparent organic window plate, and a magnetic steel frame is adhered to the outer end face of the periphery of the damage opening. A magnetic cover plate covers the damage opening, the magnetic cover plate and the magnetic steel frame attract each other, and the driving mechanism pulls the magnetic cover plate to move so that the damage opening can be opened. According to the active control device, active control to multiple damage opening plans can be realized; and according to damage stable model test characteristics and test research contents, real-time switching of various damage opening schemes in waves is realized.

Description

technical field [0001] The invention relates to the technical field of ship damage stability model tests, in particular to an active control device for ship damage stability model tests. Background technique [0002] Ship damage stability is an important performance to measure the safety of ship navigation. When the side or bottom of the ship is damaged due to accidents such as collision, grounding, and rocking, it will cause the ship to sink or capsize, which poses a serious threat to the safety of ship navigation. . The survivability of a damaged ship is an important indicator for evaluating the safety of a damaged ship. It is necessary to establish a prediction method and model test technology for the unstable motion of a damaged ship based on the research on the motion characteristics of a damaged ship and comprehensively consider the environmental conditions of the damaged ship. Ship survivability assessment provides effective technical means. [0003] The traditional...
