The data storage system can be set up separately, integrated on the server 104, or placed on the cloud or other servers. The terminal 102 can send the total equivalent of explosives and the shock wave overpressure formula of a single explosive explosion to the server 104. After receiving the total equivalent of explosives and the shock wave overpressure formula of a single explosive explosion, the server 104 divides the total equivalent of explosives into multiple parts, and the shock wave overpressure superposition coupling formula is used. Based on the shock wave overpressure superposition coupling formula, the shock wave overpressure superposition coupling value after multiple explosives are simultaneously detonated is maximized, and the Lagrange multiplier method is used to solve the optimal mass ratio of each explosive. The server 104 can feedback the optimal mass ratio to the terminal 102. In addition, in some embodiments, the method for solving the optimal mass ratio of the shock wave effect of explosive detonation can also be implemented by the server 104 or the terminal 102 alone.

[0032] The terminal 102 may be, but is not limited to, various desktop computers, laptop computers, smart phones, tablet computers, IoT devices, and portable wearable devices. The IoT devices may be smart speakers, smart TVs, smart air conditioners, smart vehicle-mounted devices, etc. The portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. The server 104 may be implemented as an independent server or a server cluster consisting of multiple servers, or may be a cloud server.

[0033] In an exemplary embodiment, Figure 2 As shown, a shock wave overpressure superposition coupling formula is provided. The method is executed by a computer device, and can be executed by a computer device such as a terminal or a server alone, or can be executed by a terminal and a server together. In the embodiment of the present application, the method is applied to Figure 1 The server 104 in the example is used for explanation, and the steps include the following steps 201 to 205.

[0034] Step 201, obtaining the total explosive equivalent and the shock wave overpressure formula of a single explosive explosion. The shock wave overpressure formula is a formula for calculating the shock wave overpressure based on the distance from the center of the explosive to the target and the explosive equivalent.

[0035] In an exemplary embodiment, the shock wave overpressure formula for a single explosive explosion is:

[0036]

[0037] Among them, ΔP mis the shock wave overpressure, W is the explosive equivalent (in kg), R is the distance from the center of the explosive to the target (in meters), a1, a2, a3 are combination coefficients, which can be 0.084, 0.27, 0.7 in the engineering design specifications, or 0.067, 0.301, 0.431 based on the test summary.

[0038] Step 202, the total explosive equivalent is arbitrarily divided into a plurality of portions, wherein the distance from the center of each portion of explosive to the target is the same. Specifically, the total explosive equivalent is arbitrarily divided into n portions, where n is a positive integer.

[0039] Step 203, constructing a shock wave overpressure formula for the explosion of each explosive based on the distance from the center of each explosive to the target, the mass of each explosive and the shock wave overpressure formula for the explosion of a single explosive.

[0040] In an exemplary embodiment, the shock wave overpressure formula of the explosion of the i-th explosive is:

[0041]

[0042] Among them, ΔP mi is the shock wave overpressure of the explosion of the i-th explosive, i = 1, 2...n, n is the number of explosives, b i W is the mass of the i-th explosive, b i is the mass ratio of the i-th explosive, 0≤b i ≤1, b1+b2+…+b n =1, let b1≤b2≤…≤b n , then W=(b1+b2+…+b n )W.

[0043] Step 204, based on the shock wave overpressure formula of each explosive explosion, determine the shock wave overpressure superposition coupling formula after multiple explosives are simultaneously detonated:

[0044]

[0045] Among them, ΔP m' is the superposition coupling value of the shock wave overpressure after multiple explosives are detonated simultaneously, is the first mass ratio parameter, is the second mass ratio parameter.

[0046] Step 205, based on the shock wave overpressure superposition coupling formula, with the goal of maximizing the shock wave overpressure superposition coupling value after the simultaneous detonation of multiple explosives, the Lagrange multiplier method is used to solve the optimal mass ratio of each explosive.

[0047] In an exemplary embodiment, find i≤1, i=1, 2…n, b1+b2+…+b n =1, satisfying and The maximum value solution. Step 205 includes the following steps (1) to (5):

[0048] (1) Based on the first mass ratio parameter term and the Lagrangian multiplier factor, the first Lagrangian multiplier function is constructed: Among them, F1(b1,b2,...,b n ,λ) is the first Lagrange multiplier function, and λ is the Lagrange multiplier factor.

[0049] (2) Based on the second mass ratio parameter term and the Lagrangian multiplier factor, the second Lagrangian multiplier function is constructed: Among them, F2(b1,b2,...,b n ,λ) is the second Lagrange multiplier function.

[0050] (3) According to the first Lagrangian multiplier function, each mass ratio in the first mass ratio parameter item and the Lagrangian multiplier factor are differentiated to obtain a first set of equations: in, is the equation about b1 in the first system of equations, is the first set of equations about b n The equation, F' 1,λ is the equation about λ in the first system of equations.

[0051] (4) According to the second Lagrangian multiplier function, each mass ratio in the second mass ratio parameter term and the Lagrangian multiplier factor are differentiated to obtain a second set of equations: in, is the equation about b1 in the second system of equations, is the second set of equations about b n The equation, F' 2,λ is the equation about λ in the second set of equations.

[0052] (5) Solving the first set of equations and the second set of equations respectively to obtain the optimal mass ratio of each portion of explosive.

[0053] In this embodiment, after solving the first and second equations, The maximum value solution is satisfy The maximum solution of

[0054] It can be seen from this that after the explosive with explosive equivalent W is divided into n parts, in order to maximize the overpressure value after the shock wave superposition coupling of each part of explosive, the optimal mass ratio is That is, n portions of explosives are divided into equal parts.

[0055] The present application provides a method for calculating the explosive mass ratio for the best shock wave overpressure superposition effect when multiple explosives are detonated simultaneously when the mass of explosives is fixed. Based on the classical calculation formula for explosion shock wave overpressure, a shock wave superposition coupling formula after multiple explosives are detonated simultaneously at the same distance is obtained, and the Lagrange multiplier method is used to theoretically give the optimal mass ratio when the superposition effect is maximum. This can provide a certain reference for blasting demolition design and has certain economic benefits in the engineering field.

[0056] In order to verify the effectiveness of this application, two implementation cases are provided below.

[0057] Implementation case 1: shock wave overpressure superposition coupling calculation with explosive mass ratio of 0.3:0.7.

[0058] 1) Determine the shock wave overpressure formula for a single explosive explosion with explosive equivalent W and distance from the center of the explosive to the target R. The combination coefficients a1, a2, and a3 are 0.084, 0.27, and 0.7, respectively.

[0059]

[0060] 2) After determining that the explosive with explosive equivalent W is divided into two parts, 0.3W and 0.7W, the shock wave overpressure formula of each part of explosive explosion is:

[0061]

[0062] 3) Determine the shock wave overpressure superposition coupling formula after two explosives of mass 0.3W and 0.7W are detonated simultaneously:

[0063]

[0064] Implementation case 2: shock wave overpressure superposition coupling calculation with explosive mass ratio of 0.5:0.5.

[0065] 1) Determine the shock wave overpressure formula for a single explosion with explosive equivalent W and distance from the center of the explosive to the target R. The combination coefficients a1, a2, and a3 are 0.084, 0.27, and 0.7, respectively.

[0066]

[0067] 2) After determining that the explosive with explosive equivalent W is divided into two parts of 0.5W and 0.5W, the shock wave overpressure formula of each part of explosive explosion is:

[0068]

[0069] 3) Determine the shock wave overpressure superposition coupling formula after two explosives of mass 0.5W and 0.5W are detonated simultaneously:

[0070]

[0071] From the shock wave overpressure superposition coupling formula of the above two cases, it can be seen that the explosion shock wave overpressure after the explosive is divided into two equal parts is greater than the overpressure value with a mass ratio of 0.3:0.7, which means that the explosion shock wave effect of equally divided explosives is better than that of unequally divided explosives.

[0072] In order to make the above theoretical case clearer, the following simulation scheme is made according to the above best implementation case: Q235B steel is used to make square steel tubes, the size of the square steel tubes is 70mm×70mm×70mm, and the wall thickness of the steel tubes is 3.75mm. Take a total charge of 0.9kg, two equal explosives (0.45kg each), and two unequal explosives (0.27kg and 0.63kg). Each explosive is made into a cube, arranged horizontally along the axis of the square steel tube and located directly above it. The net distance between each explosive is 5mm, and the distance from the center of the explosive to the explosion surface of the square steel tube is 500mm. The spatial layout diagram is as follows Figure 3 and Figure 4 The numerical simulation calculations were carried out by using LS-DYNA finite element software and the simultaneous detonation method, and the vertical deflection time history curves at the maximum deformation of the back explosion surface of the steel pipe under each working condition were extracted. The time history curves of two equal explosives and two unequal explosives are shown in Figure 5 As shown, it can be seen that the deflection of the steel pipe under the two equally divided explosives is larger than that under the two unequally divided explosives. This shows that the equally divided explosives have better explosion effects than the unequally divided explosives, and have more significant effects on the target, which can achieve better economic results in the engineering field.

[0073] The present application also provides an application scenario, which applies the above-mentioned method for solving the optimal mass ratio of the shock wave effect of explosive detonation. Specifically: The method for solving the optimal mass ratio of the shock wave effect of explosive detonation provided in this embodiment can be applied in the blasting demolition scenario. During blasting demolition, the total equivalent of the explosives is first obtained, and the optimal mass ratio of each portion of explosives is determined by using the method for solving the optimal mass ratio of the shock wave effect of explosive detonation provided in this application. The explosives are divided into multiple portions based on the optimal mass, and are placed around the blasting target respectively, and the distance between each portion of explosives and the blasting target is the same, and the blasting target is demolished by blasting, thereby improving the effect of blasting demolition.
