A simulation test device for the recoil force of hydrodynamic high-frequency projectiles

Abstract

The invention relates to a hydrodynamic high-frequency cannonball launching recoil simulation test device, which belongs to the technical field of hydrodynamic test simulation systems. In order to overcome the existing hull stability test, the stability of the ship under special operating conditions is not considered, there are deficiencies in the test process, and there is no research and analysis on the impact of continuous pulsed shell recoil on the hull during the high-frequency firing process of ship shells. For technical issues such as the influence of the attitude angle, the design includes the shell positioning transmission device 1, the cam rotation high-frequency percussion structure 2, the upper end surface of the ship model 3 and the shell direction adjustment structure 4, which can provide an equivalent for the test model. The high-frequency projectile launch impulse action conditions more realistically simulate the test environment of scale model water surface shooting operations, avoiding the shortcomings of traditional stability tests that do not consider the impact of projectile firing on the hull, thereby more realistically simulating the water dynamics of the ship Stability, improve the accuracy of ship hydrodynamic test.

Description

technical field [0001] The invention belongs to the technical field of hydrodynamic test simulation, and in particular relates to a recoil simulation test device for launching a hydrodynamic high-frequency shell. 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 fol...
