It can be understood that the aforementioned execution subject does not constitute a limitation on the embodiments of the present application, and accordingly, the operation steps of the present method can be but are not limited to the following steps S1 to S6.

[0070] S1. Obtain the blasting parameters, usage parameters and plate structure of the target protection plate corresponding to the usage scenario of the target protection plate; in the specific implementation, the blasting parameters may include but are not limited to the projectile parameters, and the projectile parameters may include but are not limited to the average thickness of the shell, the average inner diameter of the shell, the weight of the projectile charge and the weight of the shell; further, the usage parameters may include but are not limited to the total outer protection area of ​​the flexible protective structure and the set total mass of the target protection plate, and the plate structure may include but is not limited to the structural form of the panel + support layer + back plate (including adhesive material), specifically, from top to bottom, it is arranged in sequence as a crack arrest layer 10, a panel 20, an adhesive layer 30, a support layer 40, an adhesive layer 30 and a back plate 50, and its structural schematic diagram can be seen in Figure 6 As shown; in this way, after obtaining the aforementioned data, the blasting protection index and specification parameters corresponding to the target protection plate can be determined, and the process can be but not limited to as shown in the following steps S2 and S3.

[0071] S2. Based on the blasting parameters, determine the blasting protection index of the target protective plate; in the present embodiment, the blasting protection index is calculated by the anti-blasting impact scenario (i.e., the usage scenario) set in step S1; specifically, the blasting protection index of the target protective plate is determined from two aspects: fragment load mass and fragment penetration speed, wherein the calculation process of the fragment load mass and the fragment penetration speed can be, but is not limited to, as shown in the following steps S21 to S24.

[0072] S21. Determine the intermediate parameters of blasting and the initial velocity of fragments according to the parameters of the projectile body; in specific applications, for example, but not limited to, calculating the intermediate parameters of blasting according to the average thickness of the shell and the average inner diameter of the shell, and calculating the initial velocity of fragments using the weight of the projectile charge and the weight of the shell.

[0073] Optionally, one of the two calculation methods is disclosed below:

[0074] In this embodiment, the blasting intermediate parameters can be calculated by, for example but not limited to, using the following formula (1).

[0075]

[0076] In the above formula (1), M represents the intermediate parameter of blasting, t c represents the average thickness of the shell, d i represents the average inner diameter of the cartridge case, B x represents the explosion constant.

[0077] Thus, based on the aforementioned formula (1), the intermediate parameters of the blasting can be calculated, and then the initial velocity of the fragments can be calculated, wherein the initial velocity of the fragments can be calculated, for example but not limited to, according to the following formula (2).

[0078]

[0079] In the above formula (2), V0 represents the initial velocity of the fragments, W represents the charge weight of the projectile, and W c represents the weight of the cartridge case, wherein G represents an explosion energy constant (i.e., Gurney explosion energy constant), and a, c, and δ all represent constants; in a specific implementation, for example, a, c, and δ may be, but are not limited to, 304.8, 1, and 0.5, respectively.

[0080] In this way, based on the above formula (2), the initial velocity of the fragments can be calculated; then, with the help of the blasting intermediate parameters and the initial velocity of the fragments, the fragment load mass and the fragment penetration velocity of the target protective plate under different blasting confidence levels can be calculated; wherein, the specific calculation process of the fragment load mass can be but is not limited to as shown in the following step S22.

[0081] S22. Based on the intermediate parameters of the blasting, the fragment load mass of the target protective plate at different blasting confidences is calculated, wherein the blasting confidence is used to characterize the probability that different fragment load masses are the maximum weight of fragments produced by the explosion; in specific implementation, the blasting confidence essentially characterizes the designed fragment load mass (i.e., the designed fragment weight), which is the probability of the maximum weight of the fragments produced during the explosion, and therefore, by substituting different blasting confidences, the fragment load mass of the target protective plate at different blasting confidences can be calculated; wherein, since the calculation process of the fragment load mass is the same under each blasting confidence, any blasting confidence is taken as an example for specific explanation below.

[0082] Optionally, for any blasting confidence, the fragment load mass of the target protective plate at any blasting confidence may be calculated by, for example but not limited to, the following formula (3).

[0083] W f =Mln 2 (1-CL)×γ (3)

[0084] In the above formula (3), W f represents the fragment load mass of the target protection plate under any blasting confidence, M represents the blasting intermediate parameter, CL represents any blasting confidence, and γ represents a constant; wherein, in this embodiment, γ can be, but is not limited to, 28.3495231.

[0085] In this way, by substituting different blasting confidences into the aforementioned formula (3), the fragment load mass of the target protective plate at different blasting confidences can be calculated; and after calculating multiple fragment load masses, the aforementioned fragment initial velocity can be combined to calculate the fragment penetration velocity of the target protective plate at different blasting confidences, and the process can be but is not limited to as shown in the following step S23.

[0086] S23. Calculate the fragment penetration speed of the target protective plate at different blasting confidence levels based on the initial velocity of the fragments and the fragment load mass of the target protective plate at different blasting confidence levels. In specific implementation, any blasting confidence level is taken as an example for explanation, wherein the example may be, but is not limited to, the following formula (4) to calculate the fragment penetration speed of the target protective plate at any blasting confidence level.

[0087]

[0088] In the above formula (4), V S represents the fragment penetration speed of the target protection plate under any blasting confidence, V0 represents the initial speed of the fragment, W f represents the fragment load mass of the target protection plate under any blasting confidence, where S represents the fragment flight distance, and are all constants; in this embodiment, the aforementioned fragment penetration speed is equivalent to the fragment penetration speed after the fragment flies S distance, and for example Set them to 0.3048, 28.3495231 and 0.333 respectively.

[0089] Therefore, through the aforementioned formula (4), the fragment penetration speed of the target protective plate under different blasting confidences can be calculated; then, combined with the fragment load mass calculated in the aforementioned step S22, the blasting protection index of the target protective plate can be generated, and the process can be but not limited to as shown in the following step S24.

[0090] S24. Utilize the fragment load mass and fragment penetration speed of the target protection plate at different blasting confidence levels to form the blasting protection index of the target protection plate.

[0091] Therefore, through the aforementioned steps S21 to S24, the blasting protection index of the target protective plate in the set anti-explosion impact scenario can be determined; then, the specification parameters of the target protective plate, that is, parameters such as size, area, and weight, can be calculated based on the usage parameters obtained in step S1; wherein, the process of determining the rule parameters is shown in the following step S3.

[0092] S3. Determine the specification parameters of the target protective plate according to the usage parameters; in specific applications, for example, but not limited to, the following steps S31 to S34 can be used to determine the rule parameters of the target protective plate.

[0093] S31. Obtain the single-person carrying weight, and determine the actual weight of the target protective plate based on the single-person carrying weight; in the present embodiment, the single-person carrying weight is a preset value. Therefore, considering the practical application, it should be ensured that the actual weight of the target protective plate is less than or equal to the single-person carrying weight. Optionally, a weight fluctuation range can be set, and then, based on the single-person carrying weight, the weight fluctuation range can be reduced to serve as the actual weight of the target protective plate.

[0094] After obtaining the actual weight of the target protective plate, the surface density of the target protective plate can be determined, and the process can be but not limited to the following step S32.

[0095] S32. Based on the total outer protection area and the set total mass, determine the surface density of the target protection plate; in specific implementation, for example, but not limited to, the ratio between the set total mass and the total outer protection area can be used as the surface density of the target protection plate; thus, after obtaining the surface density, the area and size of the target protection plate can be determined based on this, and the process can be but not limited to as shown in the following step S33.

[0096] S33. Determine the area and size of the target protective plate based on the surface density of the target protective plate; in the present embodiment, the area is determined based on the surface density, and then the size is determined based on the area; in the present embodiment, the target protective plate is taken as an example to adopt a rectangular structure, and therefore, its size is the length and height; wherein, the aforementioned size can be determined by permutations and combinations; further, the length and height are generally multiples of 10, and of course, the aforementioned examples are merely illustrative and are not limited thereto.

[0097] After the actual weight, area and size of the target protective plate are determined through the aforementioned steps S31 to S33, the specification parameters of the target protective plate can be generated based on this, and the process can be but not limited to as shown in the following step S34.

[0098] S34. Utilize the actual weight, area and size of the target protective plate to form the specification parameters of the target protective plate.

[0099] Therefore, through the aforementioned steps S31 to S34, the specification parameters of the target protective plate can be determined, and then, the target protective plate can be simulated in combination with the blasting protection index determined in the aforementioned step S2, so as to determine its corresponding blasting test method, so that a blasting penetration test can be carried out based on the determined blasting test method, and then the optimal protective material can be determined based on the blasting penetration test; wherein, the simulation process can be but is not limited to as shown in the following step S4.

[0100] S4. Perform blasting simulation on the target protective plate by using the blasting protection index, the specification parameters and the plate structure, so as to obtain the blasting test method of the target protective plate after the blasting simulation, and visualize the blasting test method so that the user can perform blasting penetration tests on several protective samples corresponding to the target protective plate according to the blasting test method to obtain blasting penetration test data of each protective sample; in this embodiment, the blasting simulation is realized according to the blasting protection index and specification parameters of the protective baffle, and the finite element analysis software LS-DYNA is used for modeling. Among them, during the simulation process, on the basis of the aforementioned blasting protection indicators and rule parameters, the aforementioned plate structure is selected (specifically, the panel material is SiC ceramic, the supporting layer is glass fiber board, and the back plate is PE board, that is, the structure of SiC ceramic-glass fiber board-PE board) as the intrinsic performance parameter of the protective baffle during simulation, and No. 45 steel is set as the intrinsic performance parameter of high-speed fragments. Then, the penetration effect is analyzed from different incident angles to obtain different analysis results, so that the incident angle of the target protective plate can be determined according to the analysis results, and the incident angle can be used as the blasting test method.

[0101] Optionally, this embodiment provides a schematic diagram of the finite element simulation of the penetration effect of fragments at 90 degrees and 45 degrees, which can be seen in Figure 2 and Figure 3 As shown, from Figure 2 and Figure 3 It can be seen intuitively that when the incident angle is 90 degrees, the degree of penetration damage is greater and the back bulge is more obvious.

[0102] At the same time, this embodiment also provides a fragment penetration displacement-time relationship curve at different angles, which can be seen in Figure 4 As shown, from Figure 4 It can be seen that under the same penetration time, the vertically incident fragments have a greater penetration depth and a stronger destructive ability. When the penetration time is 55 microseconds, the vertically incident high-speed fragments will penetrate the target protective plate, while the obliquely incident fragments have a relatively slow penetration speed and a longer path, and the destructive ability is significantly reduced. No complete penetration occurs under the structural simulation conditions.

[0103] Correspondingly, this embodiment also provides a curve diagram of the relationship between the residual velocity of the fragments and time at different angles, which can be seen in Figure 5 As shown, from Figure 5 It can be seen intuitively that the fragments with oblique incidence slowly decrease in speed over a longer period of time, while the fragments with vertical incidence quickly decrease in speed and then penetrate the target.

[0104] Therefore, through the above-mentioned finite element simulation, it can be known that the destructive ability of high-speed fragments with vertical incidence (i.e., the incident angle is 90 degrees) on the target protective plate is much higher than that with oblique incidence; therefore, the vertical incidence method can be used as the blasting test method of the target protective plate, that is, the vertical incidence method is selected to carry out the blasting penetration test; in this way, when the target protective plate achieves complete protection against high-speed fragments, it can meet the protection needs of various angles of penetration with maximum performance.

[0105] Based on this, the aforementioned blasting test method is visualized, so that users can conduct blasting penetration tests in this way, thereby obtaining corresponding test data; in specific implementation, different materials are selected according to the composite basic structure of the protective baffle and the surface density requirements. In this embodiment, samples of different schemes such as SiC+carbon plate+PE, B4C+carbon plate+PE, SiC+fiberboard+PE are selected to conduct blasting penetration tests, thereby obtaining blasting penetration test data of different protective samples; then, the aforementioned blasting penetration test data is uploaded to the simulation end, and the optimal protective material can be determined; wherein, the process of obtaining the blasting penetration test data can be but is not limited to as shown in the following step S5.

[0106] S5. In response to human-computer interaction operations, blasting penetration test data of several protective panels are obtained, wherein the structure of each protective panel is the same as the panel structure of the target protective panel, and each protective panel corresponds to a different protective material; in this embodiment, after obtaining several blasting penetration test data, the optimal material of the target protective panel can be determined based on this; wherein the process of determining the optimal material can be but is not limited to as shown in the following step S6.

[0107] S6. According to the blasting penetration test data of each protective template, the optimal protective template is screened out from a number of protective templates, and the protective material corresponding to the optimal protective template is used as the optimal material of the target protective plate, so that the specification parameters, plate structure and optimal material of the target protective plate can be sent to the processing end, so that the processing end can process the target protective plate according to the specification parameters, the plate structure and the optimal material; in this embodiment, according to the blasting penetration test data of each protective template, the protective template that meets the blasting protection performance is first screened out from each protective template; then, the cost corresponding to each screened protective template is obtained, and finally, the protective material corresponding to the protective template with the lowest cost is used as the optimal material of the target protective plate; in this way, after determining the optimal material of the target protective plate, the optimal material, the specification parameters determined in the aforementioned step S3 and the template structure in step S1 are sent to the processing end as processing control parameters, so that the processing end can perform batch processing of the target protective plates according to the aforementioned processing control parameters.

[0108] Furthermore, in the present embodiment, after determining the optimal material of the target protective plate, the assembly method of the target protective plate can be generated according to the optimal material and optimal protective structure of the target protective plate, and the assembly method can be visually displayed; specifically, in the present embodiment, the aforementioned optimal material, structure and specification parameters are sent to the assembly terminal for visual display, so that the user corresponding to the assembly terminal can determine the assembly method based on the aforementioned data and upload it to the assembly end, and then the assembly end sends it to the simulation end, so that the assembly method of the target protective plate can be obtained.

[0109] Among them, for example, the target protection plate adopts a cloth pocket and plate plug-in structure, that is, a cloth pocket is arranged on the outer layer of the flexible protection structure, and then the target protection plate is inserted into the cloth pocket of the outer layer of the flexible protection structure, and at the same time, the baffle adopts the overlapping method of roof tiles (the overlapping method is the placement method of roof tiles) to achieve seamless draping; at the same time, for easy installation, the protective baffle cloth pocket adopts a saddle bag structure, that is, before the flexible protection structure (air rib tent) is inflated, it is placed on the surface of the flexible protection structure, and after the inflation is completed, the target protection plate is placed in the cloth pocket. Furthermore, for easy insertion, the cloth pocket of the target protection plate is slightly larger than the target protection plate by 2 to 3 mm. In addition, in order to fix the target protection plate, buckles are sewn on the cloth pocket cover (the cloth pocket cover is a hook surface, and the edge of the cloth bag is a fur surface). After the target protection plate is inserted, the buckles are glued to achieve the fixation of the target protection plate.

[0110] Thus, through the production design method of the outer protective plate of the flexible protective structure described in detail in the aforementioned steps S1 to S6, the present invention determines the blasting parameters and specification parameters of the protective baffle by setting the explosion-proof impact scenario, and at the same time combines simulation technology to quickly obtain the optimal material of the protective baffle; thus, the present invention provides a feasible technical solution for the production of protective baffles of flexible protective structures, and is therefore very suitable for large-scale application and promotion.
