More particularly to a kind of experimental rig for pouring into a mould powder charge flowing environment during simulant missile penetration multilayer insulating panel.
Background technology
Military Command and Control center is the maincenter of modern war, and precision strike is carried out to it and is efficiently injured to be to win the war
Key.For example various military-political office blocks in common Military Command and Control center, communication building etc., it is characterized in that by beam, plate, column
It is formed with structural elements such as walls, from target property, Multilayer Spaced Metal Plates spaced apart can be equivalent to, be
It realizes the precision strike to target, detonates in precalculated position after generally requiring body to pass through Multilayer Spaced Metal Plates.
Currently, the continuous improvement of requirement is injured with the fast development of ammunition technology and to target efficient, inside body
Explosive payload is more and more, and in the case where shell caliber is constant, shell of the projectile body will be thinning, this makes body pass through multiple shell target process
To larger flexural deformation occur for middle casing, at this point, bursting charge will be stretched simultaneously in the opposite direction and compression,
If bursting charge is cast loading, cast loading will generate quickly flowing, and then may lead to being emerged for " hot spot ", make body
Accidental explosion occurs for powder charge, is unable to reach predetermined damage effectiveness.It is capable of real simulation bursting charge flowing environment so establishing
Experimental rig has become the concern of weapon development department for assessing safety of the body cast powder charge under different flowing environments

The non-cpntact measurement of drug can obtain Flow of Goods and Materials rate.But the measuring environment of the device is with bursting charge in military service process
In residing flowing environment there are larger difference, 1) flow rate of powder charge that can simulate of the device is relatively low, flowing time is the second
Magnitude, and bursting charge flowing time is millisecond magnitude；2) bursting charge is solid with some strength rather than tiny makes
Type powder particles, powder charge generation overall flow rather than several moulding powder particles individual flows during body is on active service；3) bursting charge
Volume does not change in flow process, only certain displacement is flowed from compressional zone to drawing zone, due to by shell and surrounding
The effect of contraction of powder charge, the flowing limited displacement of powder charge will not form the modeling powder that modeling powder device for measuring flowability is simulated
Big displacement flows.
