Description
Technical field
The invention belongs to body high speed penetration test technical field, it is related to a kind of gear to play rest device, more particularly to a kind of use
In the gear bullet rest device of long rods sub-calibre transmitted at high speed experiment.
Background technology
Body high speed penetration test is warhead development and protection works design studies high speed Penetration weapon to buried underground
The important means that hard-to-hit target is injured, in long rods sub-calibre transmitted at high speed, body is very poor with attitude after separation of the projectile seat, often
Method cannot make body keep original trajectory attitude, therefore, carry out the research that gear plays rest device, stop the card valve after separating
And bearing, effectively reduce bullet support and clash into the influence caused to projectile flight attitude, meet body and keep original trajectory attitude
Technical requirements.
The content of the invention
The purpose of the present invention is to propose to a kind of gear bullet rest device for the experiment of long rods sub-calibre transmitted at high speed, can
Influence of the bullet support shock to projectile flight attitude is enough reduced, body keeps former in having ensured the experiment of long rods sub-calibre transmitted at high speed
There is the requirement of trajectory attitude；And with simple structure, convenient for installation and maintenance, anti-collision performance is good, size is adjustable the characteristics of.
Above-mentioned using new purpose to realize, the present invention takes following technical scheme：
A kind of gear bullet rest device for the experiment of long rods sub-calibre transmitted at high speed, described gear bullet rest device has and is welded on mesh
Supporting plate I on target bearing support；Described supporting plate I is circular slab；Concentric setting is placed with described supporting plate I
Supporting plate II；Circular slab with through hole centered on described supporting plate II, and the center of supporting plate II has the straight of through hole
Bullet diameter when footpath is tested more than transmitted at high speed, the external diameter less than calibre projectiles support；It is placed with described supporting plate II slow
Punching；Wasted-energy steel plate is placed with described buffer board；There are the pros of manhole centered on described buffer board, Wasted-energy steel plate are equal
Shape, and buffer board, Wasted-energy steel plate center have diameter of the diameter of manhole with the through hole in supporting plate II identical；Institute
State buffer board, Wasted-energy steel plate to be fixed in described supporting plate II, and gear bullet support part is constituted together with described supporting plate II.
Diameter of the diameter of the supporting plate II less than supporting plate I.
The thickness of the buffer board is 5mm, a diameter of 18mm of buffer board central circular through hole, and four are reserved on four angles
Screwed hole.
The thickness of described Wasted-energy steel plate is 5mm, a diameter of 18mm of Wasted-energy steel plate central circular through hole, and four are reserved on four angles
Individual screwed hole.
The thickness of described supporting plate II is 40mm, a diameter of 18mm of central through hole, is reserved in described supporting plate II
Four screwed holes.
The back side of the supporting plate I is welded on bearing support, and the front of supporting plate I is fixedly connected with two fastenings be arrangeding in parallel
Bar.
A kind of gear bullet rest device for the experiment of long rods sub-calibre transmitted at high speed proposed by the present invention, supports in the present apparatus
Center bore after the fixation of plate, buffer board and Wasted-energy steel plate is more than bullet diameter during high speed penetration test, but less than calibre projectiles
The external diameter of support, therefore bullet can pass through device at the trial, while can stop that card valve and base pass through, realize experiment
The separation of bullet and calibre projectiles support；In sub-calibre separation of the projectile seat, can be real well using the buffer board and Wasted-energy steel plate of the present apparatus
The energy attenuation of existing high-speed flight bullet support, makes to reduce the broken of bullet support while shelves bullet support is realized, reduces because bullet support is clashed into
The influence caused to projectile flight attitude；Body keeps original trajectory attitude in having ensured the experiment of long rods sub-calibre transmitted at high speed
Requirement；And with simple structure, convenient for installation and maintenance, anti-collision performance is good, size is adjustable the characteristics of.
