Launch control device and control method for sliding test in small water tank

Abstract

The invention discloses an emission control device for a sliding test in a small water tank. The emission control device for the sliding test in the small water tank comprises a frame, a test slider,a driving device and a control device. The test slider and the driving device are mounted on the frame. The driving device comprises two parallel guide rods fixedly mounted on the frame, a magnetic impact slider slidably sleeved on the two guide rods, springs sleeved on the guide rods, and a magnetic field generator arranged on the frame. One end of the magnetic impact slider presses against the springs. The test slider is slidably mounted on the two guide rods. The output end of the control device is electrically connected with the magnetic field generator. The invention discloses an emissioncontrol method. When the magnetic field generator is powered on, the magnetic field generator pulls in the magnetic impact slider to drive the magnetic impact slider to compress the springs; and whenthe magnetic field generator is powered off, the springs push the magnetic impact slider, and the magnetic impact slider impacts the test slider to slide. The emission control device converts elasticpotential energy into kinetic energy to provide power, and has the advantages of simple structure, simple operation and high safety.

Description

technical field [0001] The invention relates to a launch control device, in particular to a launch control device and a control method for sliding tests in a small water tank. Background technique [0002] Carrying out the physical model test of the tank is one of the important technical means for the development of underwater vehicles and the scientific research of underwater motion. The physical test of the six-degree-of-freedom motion tank for underwater gliding is of great significance for evaluating the hydrodynamic performance of underwater gliding in object form. Such research involves torpedoes, submarines, new underwater vehicles, and swimmers' underwater glide performance evaluation. The current underwater six-degree-of-freedom gliding research generally adopts the method of cavitation underwater weapon gliding test, which requires the underwater launch device to provide an ultra-high initial launch velocity for the underwater vehicle model. In order to meet this...
