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, which cannot simulate the real damage state, and cannot meet the research requirements for the transient water ingress and continuous water ingress of the damaged ship; the other method is to realize the instantaneous Opening, this method cannot meet the requirements for the rapid opening time of the damaged opening, and a model test can only realize the research of one damaged opening size

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, including a hull model and a driving mechanism, the side of the hull model is inlaid with transparent organic window panels, transparent organic windows There is a damage opening in the plate, and a magnetic steel frame is attached to the outer end surface of the damage opening. The damage opening is covered with a magnetic cover plate, and the magnetic cover plate and the magnetic steel frame attract each other. The driving mechanism pulls the magnetic cover plate to move to open the damage opening. , the application can realize the active control of various damage opening schemes, and realize the real-time switching of multiple damage opening schemes in waves according to the characteristics of damage stability model tests in waves and the experimental research content.

Description

Technical field [0001] The present invention relates to the field of ship break stability model test technology, in particular an active control device for ship break stability model test. Background [0002] Ship damage stability is the importance of measuring the safety of ship navigation, when the ship due to collision, stranding, reefing and other accidents occur ship side or bottom damage, will cause the ship to sink or capsize, bringing a serious threat to the safety of ship navigation. The survivability of damaged ships is an important indicator to evaluate the safety of damaged ships, and it is necessary to comprehensively consider the environmental conditions of damaged ships on the basis of the study of the movement characteristics of damaged ships, establish a forecasting method and model test technology for the instability movement of damaged ships, and provide effective technical means for the assessment of the survivability of damaged ships. [0003] The traditional...
