Abstract
Abstract In order to study the output characteristics and influencing factors of pyrotechnic devices for weapons and equipment in deep-water environments, a simulation model of the action process of the model separation bolt under water load was established, and the changes of separation velocity and displacement of the pyrotechnic device with different variables were calculated with propellant charge, water depth and load shape as variables. The results indicate that, With the increase of propellant charge, the separation velocity of the separation bolt gradually increased, and the maximum separation velocity rise rate increased. With the increase of water depth, the velocity attenuation accelerates with the decrease of velocity, and the maximum velocity at 10 m depth is 74 m/s larger than that at 5000 m depth, and the displacement at 3 ms is about 150 times. After 5 ms, the reduction of spherical, conical and cylindrical load velocity increased sequentially, and the decrease of cylindrical load speed was 10 times that of spherical shape.
