Detailed description of the invention

Device for determining penetrators penetrating position provided by the utility model belongs to of armor facing device Point.As it is shown in figure 1, armor facing device includes that layer 1 is expanded in the deformation stacked gradually from outside to inside together, high density height extends Layer 2, explosive layer 3, sympathetic detonation array layer 4 and explosion protection layer 5.

During armor-piercing bullet (its direction of motion is as shown by arrows in FIG.) penetration, contact at first is that layer 1 is expanded in deformation.Deformation is opened up Exhibition layer 1 is to be formed afterwards by immersing shear thickening fluid (Shear Thickening Fluid, STF) by fabric.Fine Dimensional fabric can be Kevlar, PBO or UHMWPE fabric.STF refers to the fluid colloidal suspension liquid status in concentration, and it glues Property increases with the increase of shear stress, and STF is made up of dispersed phase particles and disperse medium.Wherein dispersed phase particles can be sky The mineral so existed, it is also possible to be the polymer of chemosynthesis, such as silicon dioxide and other oxide, calcium carbonate, polyphenyl second Alkene, polymethyl methacrylate etc..Disperse medium can be water, saline solution (sodium chloride solution or buffer etc.), Organic substance (second Vinyl-ethyl alcohol, Polyethylene Glycol or ethanol), mineral oil etc., it is also possible to be dissolve each other added with surfactant and oligomer several molten The compound ligand of agent.

STF in the present embodiment is by SiO₂Particle and polyethylene glycol 200 are prepared as dispersion phase and disperse medium.Become It is with monolayer Kevlar plain cloth that shape expands layer, is dipped in above-mentioned STF soaking 15 minutes, is knitted by multi-disc monolayer after taking-up Nitride layer stacks, and carries out dried, is finally encapsulated with polyethylene film.When by high-velocity armor-piercing shell penetration, wear The high speed shear effect of first bullet can make to occur between Kevlar fiber sliding, also can occur relatively to transport between Kevlar fibrous layer Dynamic, these all can make STF be in high speed shear state, and then solidifies, and makes the penetration effect of armor-piercing bullet can be extended to bigger Radius.

High density height ductile layer 2 can use copper plate to make；When by the indirect stroke of armor-piercing bullet, expanded layer by deformation The impact of 1, high density height ductile layer 2 can be formed with corresponding position, penetrators penetrating position one more much bigger than armor-piercing bullet diameter Conical hopper.

Being filled with explosive in explosive layer 3, explosive can be the high explosives such as TNT, hexogen, HMX, it is also possible to is Their mixture.

As in figure 2 it is shown, sympathetic detonation array layer 4 is laminated by double-layer structure, divide from outside to inside (in figure from right to left) It not capacitive sensing layer 4-1 and the device layer 4-2 that detonates.

The basic structure of capacitive sensing layer is as it is shown on figure 3, it is by arranging the most in length and breadth and be connected to one in a large number Tinsel (such as aluminium foil) composition risen.The tinsel of every a line interconnects at interval of a paillon foil, with The tinsel managing every string interconnects at interval of a paillon foil, and the most all of tinsel is just divided into two Point, it is transverse metal paillon foil (tinsel linked together in i.e. every a line) and longitudinal metal paillon foil (i.e. every string respectively In the tinsel that links together).After the transverse metal paillon foil of every a line is connected with each other, by an end points of each row (in figure Right side end points) also link together, constitute a public point, often another end points of row numbers the survey as corresponding line respectively Examination end points, a in Fig. 3₀₁、a₀₂、……、a₁₅It it is exactly the test end points (illustrating with 15 behavior examples in the present embodiment) of each row.With Reason, after the longitudinal metal paillon foil of every string is connected with each other, also links together an end points (upside end points in figure) of each row, Constituting a public point, another end points of each column numbers the test end points as respective column, b in Fig. 3 respectively₀₁、 b₀₂、……、b₁₄It it is exactly the test end points (illustrating in the case of 14 row in the present embodiment) of each row.

In order to realize the judgement to penetrators penetrating position, in common port and high density Gao Yan of often row transverse metal paillon foil Loading a regulated power supply between exhibition layer (the present embodiment middle-high density height ductile layer is copper plate), the positive pole of regulated power supply connects The often common port of row transverse metal paillon foil, negative pole connects copper plate, as shown in Figure 4.When original state, regulated power supply is given simultaneously The capacitor charging that the transverse metal paillon foil often gone and copper plate are constituted, until being full of, the most each row transverse metal paillon foil Test end points voltage the most equal.When armor-piercing bullet high speed penetration, copper plate can quick local dent, make corresponding with recess The electric capacity of capacitor that constitutes with copper plate of transverse metal paillon foil increase rapidly, owing to power source charges needs the regular hour (in view of the reason of pressure drop, can by setting make regulated power supply at interval of a period of time transverse metal paillon foil to often going with The capacitor charging that copper plate is constituted), then according to capacitor ultimate principle (if distance between two pole plates reduces, electric capacity Device electric capacity can increase, and when electricity one timing that electric capacity stores, both end voltage can decline), corresponding test end points a_xxVoltage Can decline.By whether measuring the decline of test lead point voltage, it is possible to determine that the position which row metal paillon foil is corresponding there occurs Copper plate caves in, thus is finally obtained the longitudinal coordinate of penetrators penetrating position.If two or three test end points simultaneously Voltage all there occurs decline, then the position that voltage declines that row metal paillon foil that maximum test end points connected corresponding is sent out Give birth to copper plate depression.

In like manner, between the common port and high density height ductile layer of each column longitudinal metal paillon foil, load a regulated power supply, In the present embodiment each column longitudinal metal paillon foil common port and often row transverse metal paillon foil common port connect same regulated power supply Positive pole.As it has been described above, by measuring each row longitudinal metal paillon foil correspondence test end points b_xxVoltage whether decline (if any two Or the voltage of three test end points all there occurs decline, then find out voltage and decline that maximum test end points), so that it may obtain and wear The lateral coordinates of first bullet penetration location.

After the lateral coordinates obtaining penetrators penetrating position and longitudinal coordinate, the penetration location of armor-piercing bullet also determines that ?.That is: the penetration location of armor-piercing bullet is can determine that by capacitive sensing layer.

On the basis of determining penetrators penetrating position, rely on the device layer that detonates to achieve that and detonate in specific location point Explosive in explosive layer 3.Detonate device layer basic structure as shown in Figure 5.The device layer that detonates includes that controller and array rise Quick-fried device, controller homogeneously connects with the test end points of all row in capacitive sensing layer and the test end points of all row, and controller is used Receive the signal of capacitive sensing layer output, thus obtain the positional information of penetrators penetrating, and the device that controls specifically to detonate Have an effect, and then realize at ad-hoc location detonating charge.The array device that detonates includes some devices that detonates arranged in length and breadth. The device that detonates that each device that detonates (circle in corresponding diagram 5 right rectangular frame) is all adjacent by wire is connected. The device that detonates of every a line connect after an end points (left side end points, i.e. c in figure₀₁、c₀₂、……、c₀₉) connect with controller, Another end points (in figure right side end points, i.e. e₀₁、e₀₂、……、e₀₉) earth lead；An end after the device connection of detonating of every string Point (in figure top end points, i.e. f₀₁、f₀₂、……、f₀₉) connect with controller, another end points (in figure lower section end points, i.e. d₀₁、 d₀₂、……、d₀₉) earth lead.

Each device that detonates has four nodes and a heating bridge silk up and down, and the circuit of the single device that detonates can It is reduced to as shown in Figure 6.Each device that detonates, when the device that detonates being adjacent connects, is to use wire to rise adjacent two The node that quick-fried device is corresponding couples together.For the single device that detonates, left sibling thereon is connected with upper node, on it Right node be connected with lower node, and left sibling and upper node are connected with right node and lower node by middle heating bridge silk Connect.For the single device that detonates shown in Fig. 6, on it, node (is i.e. in this device that detonates by the equivalent resistance of top With string and be positioned in other devices that detonate above this device that detonates heating bridge silk resistance sum) connect column upper Square end point f_xx, its lower node (that be i.e. in same string and be positioned at this initiator by the equivalent resistance of lower section with this device that detonates In other devices that detonate below part generate heat bridge silk resistance sum) connect column lower section end points d_xx, its left sibling passes through (be i.e. in same a line with this device that detonates and that be positioned on the left of this device that detonates other detonate in device for the equivalent resistance in left side The resistance sum of heating bridge silk) connect the left side end points c being expert at_xx, its right node (is i.e. risen with this by the equivalent resistance on right side Resistance sum that is that quick-fried device is in same a line and that be positioned in other devices that detonate on the right side of this device that detonates heating bridge silk) connect The right side end points e being expert at_xx.Top end points f_xxWith left side end points c_xxAll connect with controller, lower section end points d_xxWith right side end points e_xxAll earth lead GND.

It should be noted that detonate device and the metal forming in capacitive sensing layer detonated in this utility model in device layer Sheet is corresponding good at the making initial stage, it may be assumed that after penetrators penetrating position determines, namely in capacitive sensing layer with armour-piercing Play after certain tinsel corresponding to penetration location determine, corresponding with this tinsel detonate in device layer detonate device also Determining that, the corresponding relation between device that detonates in tinsel and the device layer that detonates in capacitive sensing layer can control in advance Device sets.Controller when receiving the positional information of signal acquisition penetrators penetrating of described capacitive sensing layer output, Corresponding with penetrators penetrating position detonate device place row and column applies a voltage signal respectively by giving, make and wear What first bullet penetration location was corresponding detonate, and first device detonates, and then fried in the detonating charge layer of penetrators penetrating position Medicine.

Such as, when needing the device that detonates making the i-th row, jth arrange to have an effect, controller is at the left side end points of the i-th row c_iUpper loading+V voltage, end points f above jth row_jUpper loading+V voltage, due to the right side end points e of the i-th row_iWith jth row Lower section end points d_jGround connection, therefore, the i-th row, the device that detonates of jth row heating bridge silk on the electric current that passes through be that the i-th row passes through The electric current of remaining device that detonates and jth arrange the electric current sum by remaining device that detonates, and the heating bridge silk of the device that respectively detonates is equal Identical, therefore the detonate heating bridge silk caloric value of device of the i-th row, jth row is maximum, and first this device that detonates can detonate work With, and then at this position detonating charge, finally realize the controlled of ad-hoc location and detonate.

Explosion protection layer 5 can use the material such as steel plate, foamed aluminium to make, and it is used for alleviating detonation to by the objective of defense Damage.

The armor facing device in this utility model is used to resist the process of high-velocity armor-piercing shell penetration as shown in Fig. 7 ~ Figure 11. When armor-piercing bullet high speed penetration, deformation is expanded layer and is first subjected to the penetration of armor-piercing bullet, and the high speed shear effect of armor-piercing bullet can make change Shape is expanded and sliding is occurred between the fiber in layer, and relative motion also can occur between fibrous layer, and these all make STF be in cut at a high speed Cut state, and then solidify, make the penetration effect of armor-piercing bullet can be extended to bigger radius.High density high ductibility layer (such as copper plate) is expanded layer by deformation and is acted on, it may occur that depressed deformation, and then forms a conical hopper.Sympathetic detonation battle array Capacitive sensing layer in row layer can the distance of conductor (being herein copper plate) in face of perception, when copper plate somewhere is formed by impact During conical hopper, the bottom of conical hopper can be closer to certain tinsel in capacitive sensing layer, when having reached close to distance During quick-fried threshold value, the controller device that controls to detonate accordingly have an effect (due to close to distance directly reflection test lead point voltage The size declined, and controller decides whether to detonate according to the change of the test lead point voltage received, and therefore may be used Directly decide whether to detonate close to distance to say, it may be assumed that when reaching to detonate threshold value close to distance, controller controlling accordingly Quick-fried device is had an effect), and then the explosive in detonating charge layer.Conical hopper on copper plate can be produced and squeeze by the detonation of explosive Pressure effect, forms the convergence of energy, and metal jet meeting back action at a high speed is in armor-piercing bullet, and then the penetration destroying armor-piercing bullet is made With, reduce it to the damage by protection target.
