Description
Technical field
The invention belongs to explosive wastewater technical field, and in particular to a kind of survey for the one-dimensional plate under detonation driving experiment of explosive
Fast diaphragm, explosive detonation drives the speed of metallic plate to enter in being tested using the diaphragm that tests the speed the one-dimensional plate under detonation driving of explosive
Row measurement.
Background technology
The explosive attribute testing that characterizes conventional at present mainly includes explosion velocity, detonation pressure, quick-fried hot, quick-fried appearance and acting ability test.
The experiment for studying explosive driving metal acting according to lattice Buddhist nun equation at present has two kinds, and one kind is cylinder test, and another is one-dimensional
Plate under detonation driving is tested.Wherein, cylinder test is a kind of common test for investigating power, typically passes through the experiment
Determine detonation product JWL state equation parameters.For ideal explosive, the cylinder test result of different-diameter meets the law of similitude, i.e.,
Velocity amplitude at geometric similarity position is identical with energy value, and testing obtained experimental state equation coefficient by different-diameter is
Consistent.And be currently largely composite explosives in the explosive ground, due to the presence of particular/special requirement, contain in some explosive formulations
Substantial amounts of metal powder.Due to aftereffect of the metal powder in detonation course of reaction, explosive containing metal has the wider chemical head of district
Degree, cut off diameter are big, detonation propagation of explosion ability is weaker, and reaction product composition is complicated, there is follow-up secondary response, or even repeatedly anti-
Should.Show that the capacity for work of aluminum composition is unsatisfactory for the law of similitude by different size aluminum composition cylinder tests.And one-dimensional detonation
Driving treadmill test can observe the lower movement of metallic process of explosive driving in longer test period.
Many both at home and abroad to carry out one-dimensional plate under detonation driving experiment using scanning camera, the measuring principle of the method is：Film flying
Lucite light is hit after acceleration and visits plate target.Light visit plate be made up of three pieces of rectangular strips, they surface polishing, upper surface by
Barium nitrate powder capping piece composition, shoulder height difference is 4mm.Using scanning camera, maximum sweep rate 15km/s, 3 parallel
Spacing is 20mm slit, and it is impingement area to be directed at lucite upper surface by reflective mirror.The scan line of middle slit was dress
The scan line in axle center is put, the scanning slit with both sides coordinates, radial distance can be calculated under axial symmetry hypothesis more than between slit
The film flying impact velocity of diverse location away from 20mm.Method 705.4 in current national military standard 772A-97《Plane flyer velocity method》
It is to use the method, visiting plate using high-velocity scanning camera and light determines film flying under detonation product driving, flies through 43mm to 47mm
The time interval that distance is undergone, measurement is average speed of the film flying in this region.
Method 705.4 in current national military standard 772A-97《Plane flyer velocity method》Speed measuring device is primarily present following problem：

Testing equipment, experimentation cost is high.(3) measuring distance is short, and national military standard method is 43mm-47mm.(4) test data is intended to basis
Image or wavy curve after scanning carry out artificial data processing.It tests light path debugging complexity, uses high-velocity scanning camera etc.
Expensive device, result of the test needs to be carried out at artificial data according to the waveform that the stripe pattern after scanning or data collecting instrument are gathered
Reason, and the velocity amplitude of single-point or short distance zone leveling can only be exported, and experimentation cost is high, is unfavorable for explosive and was designed in formula
Test And Research Work is carried out in journey.
