Description

Technical Field

[0001] The present invention relates to the technical field of sub-millimeter and micron-level high-speed flyer detection, and particularly relates to a recycling high-speed flyer kinetic energy detection system and method. Background Art

[0002] A high-speed flyer is a kinetic energy device formed by driving a sheet material through high-pressure gas, electro-explosion plasma, laser plasma, and explosive detonation shock waves. The high-speed flyer is an excellent short-pulse energy source and is widely used in multiple fields.

[0003] In the field of information security, the high-speed flyer can serve as the last line of defense for maintaining information security. In case of emergency, the high-speed flyer can be used to physically destroy and self-destruct the chip to prevent important data from being stolen; in the field of automotive safety, the high-speed flyer can serve as a safety guarantee for emergency cutting off the drive power supply in the event of an out-of-control state of an electric vehicle; in the field of aerospace and military, the high-speed flyer is used as an excitation energy source for device startup. The high-speed flyer has the characteristics of small volume and high energy density. The application of the high-speed flyer promotes the miniaturization of device volume and the improvement of its safety and reliability.

[0004] The high-speed flyer mainly exerts its function in the form of high-speed impact. As a kinetic energy source, the kinetic energy of the high-speed flyer has always been a hot topic of concern. At present, the methods for detecting the kinetic energy of high-speed flyers mainly include the metal indentation method (aluminum indent method, steel indent method, etc.) and the Doppler velocity measurement method. However, these methods also have obvious shortcomings. The aluminum indent and steel indent methods mainly reflect the kinetic energy of the flyer through the depth of the indent left after the flyer impacts the metal block. During the test, the flyer impacting the metal block may cause the high-speed flyer to splash, posing a certain safety risk. After the test, the metal block is recycled, and the kinetic energy of the flyer is determined by manually measuring the depth of the indent. The measurement error of the indent depth is closely related to the operator, and the test takes a long time. When using the Doppler velocity measurement method to identify the kinetic energy of the flyer, the instrument and equipment need to capture a high-speed flyer with a size of sub-millimeter level, which poses a high requirement for the accuracy of the test instrument, resulting in high equipment and test costs. Moreover, neither the indent method nor the Doppler velocity measurement method can achieve the recycling and morphology detection of the flyer. How to further expand and optimize the technical method for detecting the kinetic energy of flyers, propose a high-speed flyer kinetic energy detection technology for recyclable flyers, and achieve rapid and economical detection of the kinetic energy and morphology of flyers is a technical problem that needs to be solved urgently. Summary of the Invention

There are position adjustment grooves in the position adjustment housing; there are paddles on the laser generator and the laser receiver that are snapped into the position adjustment grooves;

[0009] The flyer receiving device includes a transparent container, and there is a flyer receiving medium in the transparent container.

[0010] The inner diameter of the bottom end of the stepped opening structure is larger than the outer diameter of the flyer generator, and the inner diameter of the top end is smaller than the outer diameter of the flyer generator.

[0013] The flyer receiving medium is a transparent liquid such as glycerol, liquid silicone, or silicone oil. The flyer receiving medium is placed inside the transparent container of the flyer receiving device.

[0014] The flyer impact medium is glycerol or other composite liquids.

[0017] The recycling high-speed flyer kinetic energy detection method of the present invention includes the following steps:

[0018] Step (1): The laser velocity measurement device emits parallel lasers perpendicular to the incident path of the flyer. The distance between the first laser beam and the bottom of the flyer receiver device is x1, and the distance between the second laser beam and the bottom of the flyer receiver device is x2. The spacing Δx between the first laser beam and the second laser beam is Δx = |x2 - x1|. Similarly, the spacing Δx between laser beam a and laser beam b is Δx = |x b —x a |.

[0019] Step (2): Start the flyer generator. The flyer generator generates a high-speed flyer to impact the liquid flyer receiving medium, and cavitation bubbles are formed behind the flyer moving at high speed in the receiving medium. When the flyer and the bubbles pass through different laser beams, laser beam shielding occurs.

[0020] Step (3): The laser velocity measurement device measures the movement displacement and movement time of the flyer in the impact medium. Since the movement of the flyer passing through different laser beams approaches a linear movement perpendicular to the laser beams, the flyer displacement x is equal to the spacing Δx between the laser beams, that is, x = Δx.

[0021] Among them, the movement time is obtained from the time interval when the flyer and the bubbles generated by it in the receiving medium contact and shield different linear laser beams. When the flyer passes through the first laser beam, laser beam shielding occurs, and the laser intensity received by the first receiver changes. The moment when the laser intensity changes is marked as t1. When the flyer passes through the second laser beam, laser beam shielding also occurs, and the moment when the second laser receiver receives the change in laser intensity is marked as t2. The time interval for the flyer to pass through the first laser beam and the second laser beam is t:

[0022] t = |t2 - t1|

[0023] Similarly, the movement time t for the flyer to pass through laser beam a and laser beam b is t = |t b —t a |

[0024] Step (4): The laser velocity measurement device transmits the movement data of the flyer in the impact receiving medium to the data processor, and the data processor calculates the acceleration a, velocity v, and kinetic energy E of the flyer at different stages in the flyer receiving medium k The calculation formulas are as follows:

[0025]

[0026] In the formula, m is the mass of the flyer, a is the acceleration of the flyer at different deceleration stages in the impact receiving medium, x is the displacement distance, and t is the time interval.

[0027] Step (5): Record the movement process of the flying chip and detect its morphology through an image capture and processing device. Specifically, use a camera to record the movement trajectory and process status of the flying chip, and use a macro microscope camera to magnify and detect the overall shape and edge morphology of the flying chip.

[0028] Step (6): Take out the flying chip from the flying chip receiving medium, clean the flying chip with deionized water and ethanol solvent, then dry it, and weigh the flying chip using an electronic balance to obtain its mass.

[0029] Preferably, the flying chip generator fixing component is a polymer or metal device, with a height of 1 mm to 50 mm, an inner diameter of 3 mm to 20 mm, and an outer diameter of 5 mm to 80 mm.

[0030] Preferably, the highly transparent container is made of glass or transparent polymer, with an inner diameter ≥ 5 mm.

[0031] Preferably, the flying chip receiving medium is a transparent liquid such as glycerol, liquid silicone, or silicone oil.

[0032] Preferably, the camera is an ordinary camera or a high-speed camera, with a frame rate of not less than 50 frames, and the macro camera is an electronic digital microscope camera with a magnification of not less than 5 times.

[0033] Working principle: The recycling high-speed flying chip kinetic energy detection system of the present invention includes a flying chip generator fixing component, a flying chip receiving device, a laser velocity measurement device, an image capture and processing device, and a fixing device. The flying chip receiving device includes a transparent container and a flying chip receiving medium, and the flying chip receiving medium is a transparent liquid. The laser velocity measurement device includes a laser generator and a laser receiver; the image capture device includes a camera and a macro camera. The flying chip receiving medium is placed inside the transparent container, the flying chip generator fixing component is placed at the upper end of the flying chip receiving device, the flying chip generator and the flying chip receiving device are fixed using the fixing device, and the image capture and processing device is located on the side and bottom of the flying chip receiving device. During the flying chip kinetic energy detection test, the flying chip receiving device realizes the deceleration and recycling of the high-speed flying chip, the laser velocity measurement device measures the speed of the flying chip at different stages of the deceleration process, the image capture device obtains the movement trajectory of the flying chip, and the data processor calculates and detects the kinetic energy of the flying chip during the deceleration process and the energy contained in the initial impact stage, and obtains the morphology of the flying chip.

[0034] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0035] (1) The present invention realizes the recovery of the flyer kinetic energy for the first time through the high-speed flyer kinetic energy inspection method. By recovering the flyer, the mass of the sub-millimeter flyer and the key data of the morphology after high-speed flight are measured, solving the problems in the prior art that it is difficult to quickly and economically detect the kinetic energy of sub-millimeter high-speed flyers and the flyers cannot be recovered for testing.

[0046] Embodiment

[0047] As Figures 1 to 6As shown, the recoverable high-speed flying chip kinetic energy detection system of the present invention includes a flying chip generator fixing component 1, a flying chip receiving device 2, a laser speed measuring device 3, an image capturing and processing device, a fixing device 6 and a data processor 7; the flying chip generator fixing component 1 is located above the flying chip receiving device 2.

[0048] Among them, the structure of the flying piece generator fixing component 1 is as follows Figure 3 As shown, it includes a shock-absorbing sleeve 101, an internal plug 102 and a shock-absorbing washer 105 at the front end of the plug 102. Among them, the shock-absorbing sleeve 101 is an explosion-proof shock-absorbing sleeve, the plug 102 is an explosion-proof plug, and the shock-absorbing washer 105 is a shock-absorbing compression washer.

[0049] The flying piece generator is placed in the sleeve 101, and is pressed to the lower end of the sleeve 101 by the plug 102 to fix the flying piece generator and prevent the flying piece generator from moving when it is in action. The plug 102 is not a traditional solid plug. The plug is hollow inside to facilitate the wiring of the flying piece generator. The front end of the plug 102 is designed with a shock-absorbing compression gasket 105 to achieve lossless compression and detonation pressure relief of the flying piece generator. The top of the explosion-proof sleeve 101 is designed as a disc-shaped structure 104, which is convenient for fixing on the upper end of the flying piece receiving device 2. The disc-shaped structure is designed with a pressure relief feeding hole 103. After the device is installed, a syringe is used to add flying piece impact medium to the inside of the flying piece receiving device 2 through the pressure relief feeding hole 103 to achieve the regulation of the liquid level of the flying piece impact medium. The pressure relief feeding hole 103 also realizes the release of system pressure during the test.

[0050] The lower end of the flying piece generator fixed component 1 is a stepped opening structure 106, and the inner diameter of the lower end of the stepped opening structure 106 is larger than the outer diameter of the flying piece generator, which is used to install and place the flying piece generator. The inner diameter of the upper end of the opening is smaller than the outer diameter of the flying piece generator, thereby limiting the flying piece generator, realizing the fixation of the flying piece generator and reserving an outlet for the emission of high-speed flying pieces. At the same time, the stepped opening structure 106 also reserves an air gap for the flying piece and the impact medium. The height of the air gap is adjusted by designing the height of the opening and the liquid level height of the flying piece impact medium, so as to avoid the capillary siphon effect between the liquid impact medium and the flying piece generator outlet, which causes contamination to the medicine in the flying piece generator. The explosion-proof and shock-absorbing sleeve 101 of the flying piece generator fixed component 1 and the internal explosion-proof plug 102 are connected by threads, and the top of the plug 102 is designed with an inner hexagonal opening to facilitate the installation and fixation of the plug.

[0051] Among them, the flyer receiving device 2 includes a transparent container and a flyer receiving medium. The flyer receiving medium is a transparent liquid. By selecting materials and adjusting the components, a liquid receiving medium with a low saturated vapor pressure and high viscosity is obtained, thereby achieving non-destructive deceleration of the flyer, and only one bubble is formed by cavitation of the high-speed flyer in the receiving medium. When the saturated vapor pressure of the liquid flyer receiving medium is relatively low and the viscosity is relatively high, usually only one bubble is generated. If the saturated vapor pressure of this medium is relatively high and the viscosity is relatively low, fine bubbles are formed under the impact of the flyer, which is not conducive to recording the state of the flyer.

[0052] The structure of the laser velocity measurement device 3 is as Figure 4 , and it includes a position adjustment housing 11, a black silicone gasket 12, a laser generator 13, a laser receiver 14, and a position adjustment groove 15. Three or more pairs of laser generators 13 and laser receivers 14 are installed in the position adjustment housing 11. There are paddles outside the laser generator 13 and the laser receiver 14, and the paddles are snapped into the position adjustment groove 15. By adjusting the corresponding relationship between the paddles and different grooves in the position adjustment groove 15, the position height of the laser generator 13 and the laser receiver 14 in the position adjustment housing 11 is adjusted, thereby realizing the adjustment of the relative distance of the laser beam. The position adjustment housing 11 is clamped by the jaws of the fixing device 6 at the jaw position, and the position adjustment housing 11 is clamped in parallel on both sides of the flyer receiving device 2. A black silicone gasket 12 is placed between the position adjustment housing 11 and the flyer receiving device 2. Under the clamping force of the jaws of the fixing device 6, the position adjustment housing 11 squeezes the black silicone gasket 12 to ensure that the position adjustment housing 11 is closely attached to the flyer receiving device 2 and prevent the sliding of the position adjustment housing 11.

[0053] The image capture device includes a camera 4, a macro camera 5, and a data processing device 7, which record the movement process of the flyer in the impact medium and collect the morphology image of the flyer.

[0054] The structure of the fixing device 6 is as Figure 5 shown, and it is composed of a base 25, a fixing rod 26, and a flyer generator fixing component holder 21, a laser velocity measurement device holder 22, a flyer receiving device holder 23, and a camera clamping device 24. The above clamping devices also have the function of adjusting the relative positions of the devices. In this embodiment, the fixing device is an iron stand or other clamping and fixing devices.

[0055] During the flyer kinetic energy detection test, the flyer generator is fixed in the flyer generator fixing component 1, the flyer receiving medium (transparent liquid) is loaded into the flyer receiving device 2, and the laser velocity measurement device 3, the camera 4, the macro camera 5, the fixing device 6, and the data processing device 7 are installed in the Figure 1 connection sequence and the equipment is turned on.

[0056] As Figure 6As shown in the figure, start the flyer generator. The high-speed flyer flies out from the opening 106 at the lower end of the flyer generator fixing component 1 and impacts the flyer receiving medium, forming a moving cavity in the flyer receiving medium. The laser velocimeter 3 measures the displacement of the cavity movement and the time interval passing through the laser beams at different intervals. The camera 4 of the image capturing device records the entire process of the cavity decelerating movement. After the flyer sinks to the bottom of the flyer receiving device 2, the macro camera 5 records the morphology of the flyer. The data processing device 7 calculates the speed, acceleration, and kinetic energy of the flyer at different stages during the process of impacting the flyer receiving medium. After the test, the flyer is recovered from the flyer receiving device 2 to obtain the flyer mass, and further calibrate the calculated kinetic energy of the flyer.

[0057] The flyer generator uses the gas generated by the explosion of the explosive or the plasma generated by high-voltage electricity to push the flyer out of the output hole of the flyer generator.

[0058] As a preferred embodiment, the flyer generator fixing component 1 is adjusted according to the flyer generator. The optional materials are polymers or metals, with a height of 1 mm to 50 mm, an inner diameter of 3 mm to 20 mm, and an outer diameter of 5 mm to 80 mm.

[0059] As a preferred embodiment, the transparent container of the flyer receiving device 2 is glass or transparent polymer, with an inner diameter ≥ 5 mm.

[0060] As a preferred embodiment, the flyer receiving medium is glycerol, liquid silicone, or silicone oil transparent liquid. The flyer impact medium is glycerol or other composite viscous liquids.

[0061] As a preferred embodiment, the camera 4 is a high-speed camera with a camera frame rate ≥ 50 frames.

[0062] The recovery-type high-speed flyer kinetic energy detection method of the present invention includes the following steps:

[0063] Step (1), the laser velocimeter emits parallel lasers perpendicular to the incident path of the flyer. The distance from the first laser beam to the bottom of the flyer receiver device is x1, and the distance from the second laser beam to the bottom of the flyer receiver device is x2. The distance between the first laser beam and the second laser beam Δx = |x2 - x1|; similarly, the distance between the laser beam a and the laser beam b Δx = |x b —x a |.

[0064] Step (2), start the flyer generator. The flyer generator generates a high-speed flyer to impact the liquid flyer receiving medium, forming a cavitation bubble behind the flyer moving at high speed in the receiving medium. The flyer and the bubble are blocked by the laser beams when passing through different laser beams.

[0065] Step (3): The laser velocity measurement device measures the moving displacement and moving time of the flyer in the impact medium. Since the movement of the flyer passing through different laser beams approaches a linear motion perpendicular to the laser beams, the displacement x of the flyer is equal to the spacing Δx between the laser beams, that is, x = Δx.

[0066] Among them, the moving time is obtained from the time interval during which the flyer and the bubbles generated by it in the receiving medium block different linear laser beams. When the flyer passes through the first laser beam, the laser beam is blocked, and the laser intensity received by the first receiver changes. The moment when the laser intensity changes is marked as t1. When the flyer passes through the second laser beam, the laser beam is also blocked, and the moment when the laser intensity received by the second laser receiver changes is marked as t2. The time interval for the flyer to pass through the first laser beam and the second laser beam is t:

[0067] t = |t2 - t1|

[0068] Similarly, the moving time t of the flyer passing through laser beam a and laser beam b is t = |t b —t a |.

[0069] Step (4): The laser velocity measurement device transmits the motion data of the flyer in the impact receiving medium to the data processor, and the data processor calculates the acceleration a, velocity v, and kinetic energy E of the flyer at different stages in the flyer receiving medium. k The calculation formulas are as follows:

[0070]

[0071] In the formula, m is the mass of the flyer, a is the acceleration of the flyer at different deceleration stages in the impact receiving medium, x is the displacement distance, and t is the time interval.

[0072] Step (5): The image capture and processing device is used to record the movement process of the flyer and detect its morphology. Among them, a camera is mainly used to record the movement trajectory and process state of the flyer, and a macro microscope camera is used to magnify and detect the overall shape and edge morphology of the flyer.

[0073] Step (6): Take out the flyer from the flyer receiving medium, clean the flyer with solvents such as deionized water and ethanol, then dry it, and weigh the mass of the flyer obtained using an electronic balance.

[0074] As a preferred embodiment, the fixing device 6 is an iron stand or other clamping and fixing devices as shown in Figure 5 the figure.

[0075] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

The description of the above embodiments is only used to help understand the system of the present invention and its core idea. At the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes.
