A water tank that can simulate a reduced pressure environment and a multi-degree of freedom underwater launch device and method of use thereof

Abstract

The application provides a water tank capable of simulating a decompression environment and a multi-degree-of-freedom underwater launching device and a use method thereof, and belongs to the technical field of ocean engineering test. The application solves the problems of insufficient flexibility, complex structure and poor environmental adaptability of a traditional underwater launching device, and provides a test method for researching the multi-degree-of-freedom motion characteristics of a cross-medium water-exiting underwater multi-degree-of-freedom motion. The application comprises a decompression water tank, a lifting platform structure, a two-degree-of-freedom holder device and a horizontal sliding platform device. The application can realize the simulation of the multi-degree-of-freedom motion conditions of an environmental pressure, an attack angle, a pitch angle, a roll angle and a heave motion single-degree-of-freedom or multi-degree-of-freedom superposition of a carrying platform, and can meet the inclined launching test of a water-exiting vehicle. The application is mainly applied to the simulation of the underwater multi-degree-of-freedom motion of a cross-medium vehicle under a scale model ejection condition.
