Local cabin section model for ship impact resistance test

Abstract

The invention provides a local cabin section model for a ship impact resistance test, which is a box body formed by a dual-layer bottom compartment, a ballast compartment and a buoyancy reserve compartment. The shape of the cross section of the box body is as same as the shape of an area with length being 5-7 times of frame space along the length direction of a ship to be tested, width being halfof the width of the ship along the width direction of the ship and height being above 3-5m from the bottom of the ship up to the inner bottom along a vertical direction. The dual-layer bottom compartment is arranged at the bottom. The buoyancy reserve compartment is arranged right above the dual-layer bottom compartment. The ballast compartment consists of two independent watertight compartments,which are respectively arranged at the front and the rear of the dual-layer bottom compartment and the buoyancy reserve compartment. By designing a 1:1 actual-size typical cabin section model to carry out relevant impact resistance tests to research the local strength of a ship structure, the inaccuracy caused by a too simplified structure during a local grillage model test can be effectively remedied, the defects of high expense, difficult implementation and the like of a real ship test can be avoided and the problem that a scale model test is difficult to be converted into a similar test ofa real ship can be solved at the same time.

Description

technical field [0001] The invention relates to a ship shock resistance test model, in particular to a ship partial compartment model which can be used for the shock resistance test. Background technique [0002] Ships will inevitably be subjected to various impact loads during navigation, such as collision force loads in collisions, grounding accidents, and explosion impact loads, which threaten the vitality of ships. The shock response law and strength check of local structures are of great significance to the vitality of ships. At present, my country's ship shock resistance test mainly focuses on three aspects: real ship shock resistance test, local plate frame shock resistance and scaled structure shock resistance. Due to the huge cost of actual ship testing and the difficulty in implementation, under the current national conditions in our country, tests can only be carried out on individual ships; although the cost of local grillage tests is relatively low, due to the ...

Due to the huge cost of actual ship testing and the difficulty in implementation, under the current national conditions in our country, tests can only be carried out on individual ships; although the cost of local grillage tests is relatively low, due to the difference between the test model and the actual structure of the hull Large differences lead to large differences in structural responses, and the accuracy of local strength assessment of ships is low; scaled model tests not only have certain difficulties in model manufacturing, but also the results obtained cannot be converted to real ships through similar relations, nor can they Using this method to effectively evaluate the local strength of the ship
