An Equivalent Test Model of Explosion Effect in Naval Ship Compartment

Abstract

The invention discloses an equivalent test model of explosion effect in a ship cabin, which includes a main cabin, an adjacent cabin, a circumferential support column, a pressure measurement hole, a shock wave pressure measurement component, a charging hole, and a dynamic deformation measurement system. Its main features It simplifies the multi-compartment structure of the ship into a single-compartment structure with adjacent cabin circumferential constraints. The size of each wall plate is determined according to the 1:4 scale of the prototype, and the plate thickness is determined according to the 1:4 scale and determined by the material and The similarity criterion of the plate thickness composition is determined, and the cabin reinforcement is converted into the equivalent thickness of the wall plate according to the volume equivalent and strength equivalent and a certain ratio. The remarkable advantage of the invention is that the test model is a reduced-scale equivalent model of a ship cabin, has small scale, low production cost, and the damage effect is basically equivalent to that of a real ship, and is suitable for the test and evaluation research of the ship target damage effect.

Description

Technical field [0001] The present invention belongs to the technical field of damage assessment, mainly involving an equivalent test model of the indoor explosive effect of ship cabin. Background technique [0002] There are three main methods for the damage effect of the ship's target, the container, the equivalent cabin test method, the ship target damage evaluation or simulation, the equivalent shipping method is the main method of research, it is through the establishment of a ship The equivalence ratio of the cabin, launched the damaged effect of anti-ship combat, evaluated the damage capability of the battle. The method of experimental cost is relatively low, the experimental effects and the basic equivalent of the high-rise, such as Yu Deshui, the Chinese Engineering Physics Research Institute, etc., the study of the simulated ship structure Damage Effects, complete according to the ship The actual structure of the ship has designed a multi-capsule test model. Although th...

Problems solved by technology

The test cost of this method is lower than that of a real ship test, and the test effect is basically equivalent to that of a real ship. A multi-chamber test model is designed for the actual structure of the ship. Although the cost of the designed test model is lower than that of the actual ship, the cost of building such a complex multi-chamber structure is still too high, the scale of the model is too large, and it is not easy to process. Operation, long production cycle and other issues

Therefore, how to use the multi-compartment structure model of the ship, through the constraint equivalent of the boundary, to design the single-compartment test model of the ship class target under the internal explosion effect, and solve the high test cost and long research cycle in the process of ship class target damage assessment research become the key to the evaluation research of this kind of target damage effect
