Abstract

The invention discloses a shrink ratio equivalent test model for the explosion effect in a warship cabin. The shrink ratio equivalent test model comprises a cabin body, a pressure measurement mounting seat, a pressure measurement assembly, a vibration measurement mounting seat, an accelerometer, a support pillar, a powder charge hole and a locating block; the shrink ratio equivalent test model is mainly characterized in that the cabin body is an enclosed compartment provided with a cornice; the dimensions of all wall plates are determined according to the shrinkage scale of 1 to 4 with the prototype, and the thicknesses of the wall plates are determined according to the shrinkage scale of 1 to 4 and by the similarity criterion formed by material and the thickness of the wall plates; the restraint of an adjacent cabin for a compartment structure is simulated by the support pillar and the cornice of the compartment. The shrink ratio equivalent test model has the remarkable advantages the test model is the shrink ratio equivalent model for the warship cabin, so that the dimension is small, the manufacturing cost is low, and the destroy effect of the test model is basically equivalent to that of the actual ship; therefore, the shrink ratio equivalent test model is suitable for warship target damage effect test and evaluation research.

Description

technical field

[0001] The invention belongs to the technical field of damage assessment, and mainly relates to a test model, in particular to a scaled-down equivalent test model of a ship cabin for assessing damage effects of anti-ship weapons. Background technique

[0002] With the development of high-efficiency damage technology, the evaluation of weapon damage effectiveness plays an important role in the development and use of weapon systems. Anti-ship missiles are an important weapon for attacking naval targets at sea. In the process of anti-ship warhead demonstration, development, and acceptance, it is necessary to evaluate the damage power of the warhead to determine or accept the technical indicators of the warhead; , it is necessary to select and rationally deploy the use of anti-ship warheads based on the pre-evaluation results of the damage effects of anti-ship warheads. Research on the evaluation technology of the anti-ship warhead's damage effect on ship target...

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0015] as figure 1 and figure 2 As shown, the preferred embodiment of the present invention includes a cabin body 1 , a pressure measurement mount 2 , a pressure measurement assembly 3 , a vibration measurement mount 4 , an accelerometer 5 , a support column 6 , a charging hole 7 , and a positioning block 8 . Cabin 1 is a cuboid airtight cabin with cornices consisting of upper deck 1-1, lower deck 1-2, right transverse bulkhead 1-3, left transverse bulkhead 1-4, sideboard 1-5, and rear bulkhead 1-6. body, the scale of the cabin body 1 is 1:4 to the prototype, the stiffener on the prototype wall plate is converted to the thickness of the wall plate according to the volume equivalent method, and is added to the thickness of the original wall plate to obtain the equivalent thickness h of the bulkhead plate n , its calculation formula...
