[0026] It should be noted that, unless otherwise specified, all devices and methods in this invention employ those known in the prior art.
[0027] Traditional methods for assessing the damage of high-explosive warheads to ground vehicle targets are usually based on empirical formulas or numerical simulations. However, these methods often require a large amount of computational resources and time when dealing with damage calculations for a large number of targets, making it difficult to meet the needs of rapid decision-making in battlefield environments.
[0028] The calculation method of this invention is based on a damage dataset of a combination of standard high-explosive fragmentation munitions and standard ground vehicle targets. It rapidly corrects the damage data of standard high-explosive fragmentation munitions striking actual ground vehicle targets based on the differences between the actual ground vehicle targets and the standard ground vehicle targets (differences in geometric structure, damage characteristics, and a combination of both). Then, based on the damage equivalence coefficient, it obtains the amount of explosive charge generated by the standard high-explosive fragmentation munitions against the actual ground vehicle targets. This calculation method provides researchers and operational planners with a rapid method for calculating the damage equivalence of explosive high-explosive fragmentation warheads against ground vehicle targets. It also allows for comparison of the damage resistance capabilities of different ground vehicle targets based on the calculation results, and can be used in target damage characteristic analysis and operational plan formulation.
[0029] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.
[0030] Example: This embodiment provides a rapid calculation method for obtaining the equivalent damage of a warhead to a ground target, where the warhead is a high-explosive fragmentation warhead and the ground target is a ground vehicle target; the method includes the following steps.
[0031] Step 1: Determine the standard targets for ground vehicles.
[0032] For each type of actual ground vehicle target, a simplified three-dimensional structure is constructed to obtain the standard ground vehicle target corresponding to each type of ground vehicle target.
[0033] In step 1, based on the types of enemy targets that are of interest in the current damage assessment field, ground vehicle targets are classified into five categories: missile launchers, artillery vehicles, radar vehicles, command vehicles, and antenna vehicles.
[0034] In this embodiment, for actual ground vehicle targets, the corresponding standard ground vehicle targets are determined based on the principles of functional and structural consistency. For example, the three-dimensional geometric structure diagram of the standard ground vehicle target corresponding to the radar vehicle in this embodiment is as follows: Figure 1 As shown.
[0035] Step 2: Determine the standard missile-target combination and read the target-level damage data.
[0036] Based on the high-explosive fragmentation warhead and the standard ground vehicle targets determined in step 1, a standard missile-target combination is determined. In the standard missile-target combination, the ammunition model is consistent with the high-explosive fragmentation warhead model, and the target model is the standard ground vehicle target model corresponding to the actual ground vehicle target. The target-level damage data of the standard missile-target combination is read.
[0037] In step 2, the target-level damage data of the standard projectile combination includes the equivalent area data of the damage effect and the amount of explosive projectiles.
[0038] Step 3: Read component-level damage data of standard projectile targets.
[0039] Based on the standard missile-target combination determined in step 2, read the component-level damage data of standard munitions hitting standard ground vehicle targets; the component-level damage data includes fragment damage data and shock wave damage data of each component of the standard ground vehicle target hit by the high-explosive fragmentation warhead.
[0040] In step 3, the fragment damage data includes the number of fragments that hit each surface of each component, the fragment velocity, and the fragment kinetic energy.
[0041] In step 3, the shock wave damage data includes the peak overpressure data of the shock wave that hits each surface of each component.
[0042] Step 4: Call the actual target parameters for ground vehicles.
[0043] The actual target parameters for ground vehicles include geometric parameters and damage characteristic parameters.
[0044] In step 4, since both standard ground vehicle targets and actual ground vehicle targets use cuboids for generalization, the geometric parameters include length, width, height, material, and thickness.
[0045] In step 4, the damage characteristic parameters include the effective fragment threshold, the lower limit of the fragment damage criterion threshold, the upper limit of the fragment damage criterion threshold, the lower limit of the shock wave damage criterion threshold, and the upper limit of the shock wave damage criterion threshold.
[0046] Step 5: Correction of component-level damage data for standard munitions striking actual ground vehicle targets.
[0047] Based on the actual ground vehicle target parameters obtained in step 4, the differences between the actual ground vehicle target and the standard ground vehicle target are obtained; the differences include differences in geometric structure, damage characteristics, and differences in both geometric structure and damage characteristics; based on the component-level damage data of standard ammunition hitting the standard ground vehicle target obtained in step 3, the component-level damage data of standard ammunition hitting the actual ground vehicle target is corrected.
[0048] Step 5, the method for correcting discrepancies in component-level damage data includes the following steps.
[0049] Step 501, Correction of component-level damage data for geometric differences.
[0050] Step 50101: For shock wave damage elements, geometric differences do not involve the correction of damage data.
[0051] Step 50102: For fragment damage elements, geometric differences do not involve corrections to fragment velocity or fragment kinetic energy damage data; however, they do involve corrections to the number of fragments. The method for correcting the number of fragments is as follows: It is assumed that the number of fragments per unit area on the same component of actual ground vehicle targets and standard ground vehicle targets is consistent, i.e. ; In the formula: This represents the surface area of a component of a ground vehicle-type actual target when its geometry changes. This indicates the surface area of the component, which is a standard target for ground vehicles. This indicates the total number of fragments of a specific component of a vehicle that actually reaches the ground. This indicates the total number of fragments of a specific component that reaches a standard target for ground-based vehicles; This indicates the effective number of fragments of the component that actually reached the ground vehicle-type target. Indicates the effective number of fragments of the component that reach the standard target of ground vehicles; Step 502: Correction of component-level damage data for differences in damage characteristics.
[0052] Step 50201: For shock wave damage elements, differences in damage characteristics do not involve correction of damage data.
[0053] Step 50202: For the fragment damage element, the difference in damage characteristics does not involve the correction of the number of fragments, fragment velocity, or fragment kinetic energy; however, it does involve the correction of the number of effective fragments. The method for correcting the number of effective fragments is as follows: statistically analyze the mass and velocity data of each fragment that hits the component, and determine whether the fragment can penetrate the component according to the THOR formula. If it penetrates, it is considered an effective fragment; otherwise, it is an invalid fragment.
[0054] In this embodiment, the THOR formula is a fragment penetration formula known in the art.
[0055] Step 503: Correction of component-level damage data for common differences in geometry and damage characteristics.
[0056] Step 50301: For shock wave damage elements, the common differences in geometry and damage characteristics do not involve the correction of damage data.
[0057] Step 50302: For the fragment damage element, the difference in both geometry and damage characteristics involves the correction of damage data. The method for correcting the damage data is as follows: first, perform component-level damage data correction based on the difference in geometry according to step 501; then, perform component-level damage data correction based on the difference in damage characteristics according to step 502; finally, obtain the effective number of fragments that hit the component.
[0058] Step 6: Calculate the probability of damage to actual ground vehicle targets.
[0059] Based on the component-level damage data of standard ammunition hitting ground vehicle-type actual targets after step 5, according to the shock wave damage criterion and fragment damage criterion, the comprehensive damage probability of each component of the ground vehicle-type actual target is first calculated; then the overall damage probability of the ground vehicle-type actual target is calculated.
[0060] Specifically, step 6 includes the following steps.
[0061] Step 601: Calculate the probability of shock wave damage to the component based on the shock wave damage criterion. .
[0062] The damage criterion for shock waves is: ; In the formula: Indicates the probability of shock wave damage to a component; This indicates the lower limit of the shock wave damage threshold for a component to reach moderate damage. This indicates that the component has reached the upper limit of the shock wave damage threshold for moderate damage; This indicates the overpressure value of the shock wave reaching the surface of the component.
[0063] Step 602: Calculate the fragmentation probability of the component according to the fragmentation damage criterion. .
[0064] The criteria for fragment damage are: ; In the formula: Indicates the probability of fragment damage to a component; This indicates the lower limit of the effective number of fragments required to achieve moderate damage to a component. This indicates the upper limit of the effective number of fragments that indicate a component has reached moderate damage. This indicates the number of effective fragments that reach the surface of the component.
[0065] Step 603: Determine that shock wave damage and fragmentation damage are independent events, based on the shock wave damage probability. and fragmentation damage probability The overall damage probability of the component was calculated. .
[0066] Step 604: Determine that the damage logic relationship between the components of ground vehicle targets is "OR", and determine the probability of damage caused by the high-explosive fragmentation warhead to the ground vehicle target as a whole. ; In the formula: Indicates the probability of damage to ground vehicle targets; This indicates the total number of components for ground vehicle targets. Indicates the ground vehicle class target number The overall probability of damage to each component.
[0067] Step 7, Calculation of the damage radius.
[0068] For each target rendezvous distance, steps 5 and 6 are repeated to perform damage calculations at different rendezvous azimuth angles. First, component-level damage data for standard ammunition striking ground vehicle-type targets is corrected. Then, the damage probability to ground vehicle-type targets is calculated, ultimately yielding the damage probability of standard ammunition striking ground vehicle-type targets at a specific distance and rendezvous angle. The average damage probability from all rendezvous angles is calculated to obtain the average damage probability of ammunition striking ground vehicle-type targets at a specific distance, thus constructing the damage radius of standard ammunition striking ground vehicle-type targets.
[0069] In this embodiment, considering the influence of the target's attitude on the rendezvous result, in order to accurately construct the munition damage radius, a specific distance is considered. The probability of damage to the target is calculated under 360 different operating conditions, with the target's azimuth angle ranging from 0° to 360°, in 1° increments. Then, an average distance was obtained. Probability of damage at the location The calculation formula is: .
[0070] The damage radius obtained in this embodiment is as follows: Figure 2 As shown.
[0071] Step 8: Two-dimensional spatial mesh generation and damage probability calculation for missile-target intersection.
[0072] In the damage power circle calculated in step 7, a two-dimensional spatial grid area is delineated based on the changing trend of the damage probability of standard ammunition to actual ground vehicle targets. The size, center coordinates and area of each small grid are determined, and the damage probability of actual ground vehicle targets when the standard ammunition explodes at the center of each small grid is calculated based on the damage power circle interpolation.
[0073] In step 8, the specific process of interpolation calculation is as follows: Assume the distance from the actual target center of the ground vehicle class to the center of the small grid is... The radius of the standard ammunition's effective radius is At that time, the probability of damage to actual ground vehicle targets is The radius of the standard ammunition's effective radius is At that time, the probability of damage to actual ground vehicle targets is ,and ≤ ≤ The distance from the actual target center of the ground vehicle class to the center of the small grid is then... Probability of damage to actual ground vehicle targets .
[0074] In this embodiment, the damage probability of high-explosive fragmentation munitions on a target is calculated based on the damage radius as follows: Figure 3 As shown.
[0075] The two-dimensional damage probability matrix obtained in this embodiment is as follows: Figure 4 As shown, from Figure 4 As can be seen, the probability of munitions damaging the target gradually decreases as the distance from the ground increases.
[0076] Step 9: Calculate the equivalent area of the damage effect.
[0077] Based on the damage probability of the standard ammunition detonating at the center of each small grid obtained in step 8 (i.e., the actual damage probability of ground vehicle-type targets), Figure 4 The damage probability matrix shown is used to multiply the area of each small grid cell in the two-dimensional space by the damage probability, and then sum them up to obtain the equivalent area of the damage effect of the high-explosive warhead on actual ground vehicle targets. .
[0078] Based on the damage probability of the standard ammunition when it explodes at the center of each small grid obtained in step 8, the equivalent area of the damage effect of the standard ammunition hitting the standard ground vehicle target in the Cartesian coordinate system is calculated. ; In the formula: This represents the probability of damage to a small grid. The x-coordinate of the center of the small grid; The ordinate represents the center of the small grid. This represents the area of the small grid.
