Rotary type high-speed bump test device for circular test piece

Abstract

The invention provides a rotary type high-speed bump test device for a circular test piece. The device comprises a rotary base, a rotary panel and a circular test piece fixing device, wherein the rotary base is connected with the rotary panel by a flange plate; the circular test piece fixing device is fixedly connected with the rotary panel; the rotary type high-speed bump test device is fixed in a target cabin of a two-stage light gas gun; the test piece is fixed by the press clamp of the circular test piece fixing device; the circular test piece fixing device is formed by overlapping three flat plates, wherein circular holes formed in the centers of the flat plates have different diameters; the diameter of the hole of the middle flat plate is larger than the diameters of the flat plates arranged at the two sides; the test piece is embedded in the middle flat plate. The rotary type high-speed bump test device is simple in structure and convenient in clamp fixation of the test piece; after the rotary type high-speed bump test device is used, a multi-angle bump test of the circular test piece can be completed according to the actual demand.

Description

technical field [0001] The invention belongs to the technical field of space debris protection tests, and in particular relates to a rotatable high-speed impact test device for circular test pieces. Background technique [0002] Space debris, also known as space junk, is the waste discarded in space during human space activities. With the development of human spaceflight, the space density of space debris is increasing day by day, which has threatened the safety of spacecraft, and its number is still growing at a high speed. The impact of large space debris will change the attitude and orbit of the spacecraft, and more seriously, it will cause damage or even complete disintegration of the spacecraft; the impact of small space debris will change the surface performance of the spacecraft, damage or fail some components, and make the spacecraft Loss of function. At present, ground-based equipment can only observe, track and catalog centimeter-sized and larger debris, and spac...

Problems solved by technology

[0003] However, when the second-level light gas cannon is used in the space debris ground simulation test, the projectiles fired by the light gas cannon are always kept in a straight line, resulting in the projectiles basically hitting the target, and it is impossible to complete the multi-angle high-speed impact test.

In addition, compared with rectangular or square test pieces, circular test pieces have unique axial symmetry, but there are difficulties in clamping and fixing them
