Background technology
Space junk, also known as space trash, is the discarded object be discarded in mankind's space operation in space.Along with the development of mankind's aerospace industry, the space density of space junk increases day by day, threatens to the safety of spacecraft, and its quantity is still in rapid growth.The shock of large space fragment can make spacecraft attitude and track change, and spacecraft breakage more seriously can be caused to disintegrate even completely; The shock of little space junk can make spacecraft surface property change, and part of devices damage or inefficacy, make spacecraft loss of function.Current ground-based device can only be observed, follow the tracks of and catalogue centimetre-sized and larger fragment, and spacecraft can carry out evading and maneuvering flight according to the orbit parameter of space junk, to avoid smashing; Little space junk (< 1cm) One's name is legion, but cannot orbit measurement be carried out, the method for passive protection can only be taked, set about in spacecraft overall design, safeguard structure and material, reduce the threat of little space junk.And the matter of utmost importance solving the protection of space debris problem of spacecraft should be set up and improve the ground-based simulation equipment possessing hypervelocity impact test ability.Gas Gun, as general effective high-speed impact analog machine, not only can launch the bullet of various shape, and has broad accommodation to the quality of bullet, size and material.Two-stage light gas gun, as the one of Gas Gun, is the visual plant of virtual space fragment hypervelocity impact effect.The principle of work of two-stage light gas gun as shown in Figure 9.Its principle of work is: pump line (one-level big gun power valve) vacuumizes the light gas of the certain air pressure of rear injection, the piston adiabatic compression light gas of high-speed motion makes it form a plenum chamber at pump line end, after the air pressure of this air chamber exceedes the ability to bear of isolation diaphragm, then rupture of membranes launches the bullet holder that bullet is housed, after bullet holder enters expansion arc, bullet holder is blocked by bullet holder baffle plate, bullet in bullet holder continues flight and enters target cabin, hits testpieces.Carry out high-speed impact test time, in order to prevent High-velocity Projectiles in the windage entered in Nei Yuba cabin, target cabin ablation bullet, process must be vacuumized to target cabin.
But two-stage light gas gun be used in space junk ground simulation test often face light-gas gun launch bullet remain point-blank, cause bullet to be substantially all just impinging upon in target piece, cannot complete multi-angle high-speed impact test.In addition, compared to rectangle or square test part, circular testpieces has exclusive axial symmetry, but it grips and has difficulties.
Summary of the invention
The object of the invention is for solving above-mentioned deficiency, a kind of high-speed impact test unit for circular testpieces of rotary type is provided.
The object of the invention is to be achieved through the following technical solutions: a kind of high-speed impact test unit for circular testpieces of rotary type, comprise rotating base, rotating panel and circular testpieces stationary installation, rotating base is connected by ring flange with rotating panel, circular testpieces stationary installation is fixedly connected with rotating panel, this device is fixed in the target cabin of two-stage light gas gun, testpieces is carried out pressure by circular testpieces stationary installation clamping fixed; The flat board superposition that circular testpieces stationary installation has different-diameter circular opening by three pieces of centers forms, and the diameter of central flat hole is greater than the diameter of its both sides flat board, and testpieces is embedded in middle flat board.
The present invention also has following technical characteristic: a kind of using method of the high-speed impact test unit for circular testpieces of rotary type, and use device as above, step is as follows:
(1), this device uses in conjunction with two-stage light gas gun, is fixed on by this device in the target cabin of two-stage light gas gun, testpieces carried out pressure by circular testpieces stationary installation clamping fixed;
(2), the ring flange of rotating base can make rotating panel 15 °, 30 °, 45 ° and 60 ° of rotations, adjusts angle, by bolt, rotating panel is fixed on optional test angle;
(3), under the speed of setting, launch appointment bullet by two-stage light gas gun and clash into the circular testpieces of certain material with different angles.
Beneficial effect of the present invention is:
Apparatus of the present invention structure is simple, grips testpieces convenient, can complete the multi-angle impact test to circular testpieces according to actual needs.
