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 anti-impact test model, in particular to a ship partial cabin model that can be used for impact test. Background technique [0002] Ships will inevitably be subjected to various impact loads during navigation, such as collision loads in collisions, grounding accidents, and explosive impact loads, which threaten the life of the ship. The impact response law and strength check of the local structure is of great significance to the ship’s vitality. At present, my country's ship shock resistance test mainly focuses on three aspects: actual ship shock resistance test, local plate frame impact resistance and scaled structure impact resistance. Due to the huge cost of actual ship test and the difficulty of implementation, under China’s current national conditions, tests can only be carried out on individual ships. Although the cost of partial plate test is relatively low, the actual structure of the test model and the hull is diffe...

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
