Abstract

The invention relates to a novel hydrodynamic high-frequency cannonball launching recoil simulation test device, and belongs to the technical field of hydrodynamic test simulation systems. In order tosolve the technical problems that the stability of a ship under a special operation condition is not considered in the existing ship body stability test, the defects exist in the test process, the influence of the continuous pulse type cannonball recoil on the ship body attitude angle in the high-frequency launching process of the ship cannonball is not studied and analyzed and the like, the invention designs a simulation test device comprising a cannonball positioning and conveying device 1, a cam rotating high-frequency knocking structure 2, a ship model upper end face 3 and a cannonball direction adjusting structure 4, equivalent high-frequency cannonball launching impulse action conditions can be provided for a test model, and the test environment of a scaling model water surface shooting operation can be simulated more truly. The defect that a traditional stability test does not consider the influence condition of cannonball shooting on the ship body is overcome, so that the hydrodynamic stability of a naval vessel is simulated more truly, and the accuracy of the hydrodynamic test of the naval vessel is improved.

Description

technical field [0001] The invention belongs to the technical field of hydrodynamic test simulation, and in particular relates to a novel hydrodynamic high-frequency projectile recoil simulation test device. Background technique [0002] The stability test technology of the hull model is an important technology in the field of hydrodynamic experiment simulation system technology. In recent years, in order to maintain maritime sovereignty and the stable development of the national marine economy, naval hull design technology has also developed rapidly, and research on the stability of patrol boats when firing shells has become an important emerging research direction. The stability of the hull refers to the ability of the ship model not to capsize under limited action, and to return to the normal state after the tilting force disappears. At present, the hydrodynamic hull stability test mainly focuses on the hydrodynamic test research of the hull shape, which has the followin...
