Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of shock wave test, and particularly relates to a single soldier equipment shock wave test device and method based on equivalent simulation of a shock tube. BACKGROUND

[0002] In modern warfare, explosive weapons such as improvised explosive devices, landmines, and rocket projectiles pose a serious threat to individual soldiers. The single soldier comprehensive protection system (hereinafter referred to as single soldier equipment) aims to comprehensively protect soldiers from various battlefield injuries. At present, the research and testing of single soldier equipment (especially bulletproof clothing and bulletproof helmets) focuses on the penetration protection performance of fragments / bullets. However, practical combat experience and post-war trauma analysis clearly show that explosion shock waves have become an independent and key factor causing the death and injury of soldiers. Explosion shock waves not only can cause direct "primary explosion injury" such as eardrum rupture, lung hemorrhage, craniocerebral injury, and hollow organ injury, but also can indirectly aggravate "secondary", "tertiary", and even "quaternary" injuries such as blunt injury and shrapnel injury through the complex interaction of shock waves and the human body.

[0003] At present, the performance evaluation of single soldier equipment under explosion shock waves has the following key bottlenecks:

[0004] (1) High testing cost and difficulty in repetition: Reliance on large-scale explosion fields for live explosion tests has high cost, long preparation period, and difficulty in accurately reproducing the test environment each time, resulting in large dispersion of test results.

[0005] (2) Difficulty in accurately quantifying the "equipment-shock wave-human body" interaction in traditional field explosion experiments: The explosion environment is complex and variable (mixing of shock waves, fragments, and thermal effects), making it difficult to accurately separate and quantitatively measure the independent influence of shock waves.

[0006] (3) Inability to evaluate protection effectiveness in detail: Lack of standardized laboratory simulation techniques that can accurately control key parameters (peak value, duration, etc.), making it difficult to quantitatively evaluate the protection effect of different protective materials, structures, and configurations on specific shock wave parameters.

[0007] (4) The existing traditional high-pressure gas-driven shock tube often uses the method of pressure accumulation and membrane rupture, in which a membrane (metal or composite material) is used to separate the high-pressure chamber and the low-pressure chamber of the shock tube. The high-pressure chamber is filled with gas until the pressure exceeds the limit of the membrane, and the membrane ruptures instantly, forming a shock wave. The "pressure accumulation and membrane rupture method" inevitably produces high-speed fragments that splash. These fragments become an additional and uncontrollable interference source, causing complex penetration or blunt injury to the biological models (such as animals or dummy heads / torso with sensors) in the test, seriously confusing the independent observation and quantitative analysis of the neurosystem biomechanical effects of the shock wave itself, and reducing the reliability of the results.

[0008] (5) The lack of equivalent simulation means: lack of simulation technology that can safely and controllably reproduce the explosion shock wave with equivalent biological injury potential under laboratory conditions. Traditional explosion shock tube often uses a single power source to drive, which is difficult to adjust according to the demand of overpressure and positive pressure action time.

[0009] Therefore, it is of urgent practical value to develop a small, high-precision, low-interference shock tube test device and method specially for individual equipment explosion shock wave protection efficiency test. SUMMARY

[0054] Embodiment two:

[0055] Embodiment two of the application discloses a single soldier equipment shock wave test method based on equivalent simulation of shock wave tube, and the single soldier equipment shock wave test device disclosed in embodiment one is applied, and specifically includes the following steps:

[0056] Step S01, before carrying out the experimental work, the number of nodes and size parameters of the propagation tube 301 are selected according to the test needs, the size parameters of the wave shaping tube 302 are selected, and the propagation tube 301, the wave shaping tube 302 and the loading tube 303 are sealed and connected for assembly; the simulated single soldier equipment test product is fixedly installed at the outlet of the loading tube 303 through the support.

[0057] The setting of the single soldier equipment test product belongs to the conventional test method in the field of shock wave tube test, for example, the test dummy with single soldier equipment is set at the outlet of the loading tube 303, and pressure sensors, strain sensors and the like electrically connected with the computer 102 are arranged at the key test parts of the test product, and the specific setting mode will not be described here.

[0058] Step S02, according to the test needs, a shock wave driving mode is selected, and the charge is carried out according to the shock wave driving mode. The shock wave driving mode includes single-tube initiation driving, multi-tube simultaneous initiation driving and multi-tube delay initiation driving.

[0059] The specific steps of the charge include: selecting a cannonball matched with the caliber of the cannon bore 203, removing the bullet head and only keeping the cannonball cartridge, determining the charge amount of the gunpowder according to the parameters of the shock wave load overpressure and duration required by the experiment, filling the gunpowder in the cannonball cartridge, then opening the second sealed hatch 204, and loading the cannonball cartridge into the cannon bore 203; for the single-tube initiation driving mode, only the cannonball cartridge is filled in one cannon bore 203, and for the multi-tube simultaneous initiation driving and multi-tube delay initiation driving, according to the required shock wave characteristics, the cannonball cartridge is filled in at least two cannon bores 203.

[0060] Step S03, according to the shock wave driving mode, the initiation mode of the electric control firing device 205 is preset, and specifically:

[0061] For single-tube initiation driving mode, the single electric control firing device 205 is controlled by the initiator 104 to initiate after sending the initiation instruction; for multi-tube simultaneous initiation driving mode, all electric control firing devices 205 are controlled by the initiator 104 to initiate simultaneously after sending the initiation instruction; for multi-tube delay initiation driving mode, the initiation sequence and delay interval time of each electric control firing device 205 are preset, and each electric control firing device 205 is controlled by the initiator 104 to initiate according to the above preset after sending the initiation instruction.

[0062] The initiation refers to that the electric control firing device 205 fires the cannon cartridge in the cannon bore 203 to detonate the gunpowder in the cannon cartridge.

[0063] The three driving modes are respectively suitable for three different test requirements: the single-tube initiation driving mode is suitable for the case that the required shock wave overpressure is low and the positive pressure action time is short, and only the charge amount in the single tube needs to be adjusted to control the shock wave overpressure peak value and the positive pressure action time.

[0064] The multi-tube simultaneous initiation driving mode is suitable for the case that the required shock wave overpressure is large, and the shock wave energy is effectively distributed and continuously transmitted through the spatial layout of the cannon cartridges by the spatial superposition effect of the shock waves under the synergistic action of multiple explosion sources. The overpressure peak value and the positive pressure action time can be controlled by controlling the filling amount of gunpowder in multiple cannon cartridges.

[0065] The multi-tube delay initiation driving mode is suitable for the case that the required shock wave duration is long, and the problem of insufficient single explosion holding time is solved by precisely coupling the initiation time sequence of multiple cannon cartridges and fully utilizing the delay explosion relay mechanism. The millisecond delay initiation is performed by controlling the initiation time of the electric control firing device 205 to realize the continuous relay loading of the shock wave load, so as to achieve the purpose of prolonging the shock wave action time.

[0066] In step S04, the computer 102 is started, the acquisition software is run, the dynamic signal test analysis system 103 is started, all dynamic pressure sensors 105 are adjusted to the working state, the computer 102 sends an initiation instruction to the initiator 104, the electric control firing device 205 is controlled by the initiator 104 to perform initiation according to the preset initiation mode, the computer 102 synchronously controls the dynamic signal test analysis system 103 to collect the electric signal on the dynamic pressure sensor 105, and the dynamic signal test analysis system 103 transmits the electric signal to the computer 102 for decoupling calculation to obtain the mechanical signal.

[0067] The acquisition software can use an existing software product, for example, the Donghua DHDAS dynamic signal acquisition and analysis system.

[0068] Step S05, analyzing the electric signals collected by each dynamic pressure sensor 105, and the electric signals collected by the overpressure, strain and other sensors on the individual equipment test product, and manually observing the damage condition of the individual equipment test product, etc. The above analysis belongs to the prior art in the field of shock tube test, and relevant papers can be referred to, and the specific content will not be described herein again.

[0069] The above disclosed is only one specific embodiment of the present application, but the present application is not limited thereto, and any changes that can be thought of by those skilled in the art shall fall within the protection scope of the present application.
