Problems solved by technology

[0003] However, since the underwater explosion test of a real ship poses a lot of challenges to the country's financial resources, conducting a group of underwater explosions on a real ship will consume a lot of human, material and financial resources of the country, so how to avoid multiple groups of underwater explosion tests on a real ship , and the corresponding full research on the underwater explosion structure of the ship structure has become the main research direction of scholars at home and abroad.
[0004] The traditional underwater explosion test of ship structure is a scale test. The local boundary conditions of the structure are set and the explosion test is hoisted underwater. This method has large defects and poor simulation accuracy, which cannot be accurately Precise control of the boundary conditions of the test sample structure, and a lot of consumption in the test

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] The invention specifically relates to a device and method for conducting an underwater explosion test on land, which consists of explosives, an external water tank, a target test piece, long and short drawer tooling and bottom fixed tooling. The specific operation is to fix the base fixing tool on the ground, place the target test piece at the corresponding position, install the long and short drawer tooling and fix them with bolts, add a gasket to the upper end of the test sample, install the external water tank tooling on the top, and add bolts Secure and act as a watertight seal, placing explosives at the target location. This new test method has low cost and strong test operability, especially the control of boundary conditions is clearer, and water of different depths can be added according to different target environmental conditions, and multiple groups o...

Abstract

The invention belongs to the technical field of underwater explosion tests, and particularly relates to a device and a method for carrying out an underwater explosion test on land. In order to overcome the defects of the existing test method, the invention provides a device and a method for carrying out an underwater explosion test on land. The underwater explosion test of a ship structure is simulated on the land, a large amount of financial resources, material resources and manpower are saved, boundary condition setting of the underwater explosion test of the structure is met, the operability of the test is high, and the popularization value and the practical value are extremely high. According to the invention, a traditional ship structure underwater explosion damage test is replaced, the traditional underwater test is transferred to the land, and under the condition of equal working conditions, the test is carried out on the land, so that the test boundary conditions are more controllable, the test process is clearer, the test is simple and convenient, and a universal test method is provided for carrying out multiple groups of tests by replacing test samples.

Description

technical field [0001] The invention belongs to the technical field of underwater explosion tests, and in particular relates to a device and method for performing underwater explosion tests on land. Background technique [0002] With the development of marine science and the advancement of national defense technology, the impact resistance of ship structures subjected to underwater explosion loads and structural damage effects have attracted more and more attention from marine engineering research in various countries. Therefore, in terms of actual naval battles, underwater real ships Explosion is the actual damage effect that can best reflect the impact of underwater explosion on ship structure. For example, the United States and Japan have conducted a large number of real ship underwater explosion research, and conducted very systematic and large-scale research, and achieved many results. The anti-explosion and shock resistance performance of their ships and ship structure...
