Description
Technical field
The utility model relates to a kind of shock wave physics and detonation physics is tested the electric probe by sensor field, for the combined electrical probe of high-speed motion metal film flying test.
Background technology
The basic research fields such as high pressure property of material under the detonation property of explosive and impact compress, film flying motion state is basic measuring object, in order to characterize the high-pressure physics performance of explosive acting ability and metal material; In warhead development process, it is the key character that characterizes product design performance that explosive detonation acting drives the motion of metal film flying, the performances such as fragmentation effect, armor-penetrating ability and convergence compression degree that reflected product, being the foundation that can assessment product reach design objective, is also the check inventory foundation that whether performance declines after long-term storage.All having dropped into a large amount of man power and materials carries out specializing in of this respect both at home and abroad, and has made great progress.
Because film flying movement velocity is high, conventionally adopt electric probe test film flying to arrive the time of ad-hoc location.In experiment, electric probe is accessed in the lattice network of electric pulse formation, before experiment, by the capacitor charging in this network, by metal film flying access electronegative potential, electric probe is accessed to high potential.When the film flying of high-speed motion and electric probe collision, can export an electric pulse, by register instrument collection, as time signal, the function of electric probe is equivalent to the high-speed pulse switch in circuit.Warhead design and certificate authenticity and corresponding basic research are high to the required precision of time measurement, the uncertainty of measuring requires in tens ns, thereby can all propose specific (special) requirements to the shape of electric probe, size, antijamming capability and output electric property.
Document < < is modest through good fortune. experiment equation of state guiding (second edition). and Beijing: Science Press, 1999 > > and < < Sun Cheng latitude. application detonation physics. Beijing: National Defense Industry Press, in 2000 > >, provide multiple for shock wave physics and detonation physics experiment test electric probe kind, shape, size, material and main performance used, specific as follows:
Bulb type electric probe: be a kind of electric probe simple in structure, agent structure is a metallic conductor, for measuring the film flying flight time, test film flying flying speed be generally less than 1.5km/s.In order to guarantee the rigidity in use, conductor diameter is generally in 1mm left and right, as shorter in the probe using, and can accomplish 0.5mm diameter.
Screw thread electric probe: be on the basis of bulb type electric probe, increase the location structure of probe, the film flying flight time that is beneficial to measure ad-hoc location, the flying speed of test film flying is generally less than 1.5km/s.
Conducting resinl electric probe: be at metal tube of bulb type electric probe outer cover, inside and outside double layer of metal conductive adhesive, Main Function is the rigidity that will improve bulb type electric probe.Test film flying flying speed be generally less than 1.5km/s.
Capping type electric probe: be at metal tube of bulb type electric probe outer cover, inside and outside double layer of metal is bonding with insulating varnish, the head of this probe also has metal nut cap as strengthening structure.Due to head special construction, can overcome the interference of the front air-shock wave of film flying, the flying speed of the film flying of testing is generally at 1km/s～5km/s.
Coaxial cable electric probe: coaxial cable can be directly used in to film flying flight time measurement, the anti-space of this electric probe electromagnetic interference capability is strong.The flying speed of test film flying is generally less than 1.5km/s, and because needs carry out structural strengthening, this probe size is larger.
Separately having opening bulb electric probe and opening tack electric probe, is all in the different structure of bulb type electric probe outer wrap, in order to increase the structural strength of probe.The flying speed of test film flying is generally less than 1.5km/s.
The electric probe of above-mentioned Introduction of Literatures and the at present actual electric probe using are all absolute construction, and its size is larger.The flying speed of corresponding test film flying is at the probe of 1.5km/s, and its diameter is generally more than 1mm.The flying speed of test film flying is at the capping type electric probe of 1km/s～5km/s, and its diameter is generally more than 2mm.When the film flying of high-speed motion and electric probe collision, can produce metal splashings, coning distribute, this metal splashings speed is higher than the speed of film flying, can be before film flying arrive, object is around produced to destruction.Experiment shows, when the film flying of high-speed motion and the collision of metal thin bar, the metal splashings of generation spread towards periphery, and its scope can reach 10 times of metal thin bar diameter.Distance is nearer, and splashings density is higher, when the density of metal splashings reaches after certain value, can form the loop of conduction.Scene for film flying and electric probe collision, within the scope of 5 times of probe diameter, because splashings density is higher, can form conductive channel with film flying, cause probe around the electric probe of 5 times of diameter ranges disturbed by it, the time signal that output metal splashings arrive, rather than test the film flying run duration signal needing.
At explosive detonation, drive in the experiment of film flying, due to the impact of avris rarefaction wave,, the impact of the impact of Charge Structure on Explosive and film flying structure etc., film flying is out of shape seriously in motion process, different position on corresponding film flying, and its movement velocity is different.Because every electric probe can only provide a time data, thus large deformation film flying motion state will be measured, must intensive laying probe, could react the deflection of diverse location.Use original electric probe can bring the two disadvantageous consequences in aspect: the one, because probe diameter is larger, below film flying, can not arrange the electric probe of comparatively dense, but the particularity due to warhead design, the film flying that explosive detonation drives can produce larger distortion at motion process, lays the deflection that the excessive probe of spacing can not reflect film flying comprehensively; The 2nd, warhead design need to be understood certain position behavior of motion continuously on film flying, due to serious interference between probe, single probe can not be bundled to use, thereby a certain position behavior of motion continuously on also just cannot continuous measurement film flying, must the film flying data of motion continuously be could obtain by multiple Detonation Experiments, R&D costs and experimental cost increased.
