The effectiveness assessment runs through the entire life cycle of weapons and equipment. China started late in the use of damage assessment technology. Although computer modeling and simulation technology has been used in the damage assessment of various warheads and targets, these simulations are too single, scattered, and idealized, and have not formed a complete and mature system, which is far from the actual evaluation needs.

[0020] Embodiment: This embodiment provides a system for evaluating the damage effectiveness of a warhead on a typical target. Figure 1 As shown, the system includes a database module, a projectile-target design module, a projectile-target intersection module, a target damage assessment module, and a result output module. The database module and the projectile-target design module are connected to each other, the output end of the projectile-target design module is connected to the input end of the projectile-target intersection module, the output end of the projectile-target intersection module is connected to the input end of the database module and the target damage assessment module, the output end of the target damage assessment module is connected to the input end of the result output module, and the output end of the result output module is connected to the database module.

[0021] Specifically, the database module is used to manage various types of data such as warhead ammunition and typical target related data, simulation results, evaluation results, etc., as well as database management of standard components, and supports interface database table data operations. The database module includes material database, warhead database, warhead fragment distribution test result database, target database, projectile-target relationship database and result database. The material database stores existing materials, including metals, non-metals and explosives, supports expansion functions, and new materials can be added later; the warhead database stores existing warhead structural parameters, component materials and detonation point locations; the warhead fragment distribution test result database stores the spherical target test results of the warhead; the target database stores the types, geometric features and physical parameters of existing targets; the projectile-target relationship database stores existing projectile-target relationships, such as landing angle velocity, etc.; the result database is used to store projectile-target intersection simulation results and target damage assessment results.

[0022] Specifically, the missile-target design module is used to edit the characteristic parameters of warhead ammunition, the characteristic parameters of typical targets, and the missile-target intersection parameters. The characteristic parameters of warhead ammunition include the geometric characteristics and physical parameters of the warhead. The geometric characteristics of the warhead include the warhead type, head shape, projectile length, and diameter. The physical parameters of the warhead include projectile weight, shell thickness, charge type, and equivalent TNT mass. The characteristic parameters of typical targets include the type, geometric characteristics, and physical parameters of typical targets. The geometric characteristics include the shape, size, and thickness of typical targets. The physical parameters include the material and equivalent strength of typical targets. The missile-target intersection parameters include the impact speed, hit accuracy, impact angle, and attack angle.

[0023] When designing the projectile, you can open each database to view the existing data. There are two modes for visual editing of warhead ammunition. One is the manual input mode. By manually inputting and editing the warhead ammunition model, you can view the design results of the shell and charge in real time. If the design parameters do not match, the user will be prompted. After the manual input design is completed, the current design results can be saved to the warhead database and can be directly called later; the other is the import file mode, which imports the existing warhead type data file from the warhead database; after completing the warhead ammunition design, you can also view the characteristic quantity and power field of the ammunition. The typical target visual editing process also supports two modes. One is to edit the size, thickness, material, equivalent strength and other parameters of the typical target according to the typical target geometric model information, and the other is to directly call the data file of the typical target imported into the target database. Edit the matching projectile intersection parameters between the designed warhead ammunition data and the typical target data. The projectile design module uses the database module to complete the data integration of warhead ammunition and typical targets.

[0024] Specifically, the missile-target rendezvous module is used to demonstrate the process of missile-target rendezvous, and provides a 3D animation effect simulation of the entire process of warhead ammunition striking a typical target, which mainly includes: process control of the simulation process and special effects simulation such as sound, flash and smoke during the explosion process, as well as multiple viewing angles such as the best viewpoint and user-customized viewpoint, so as to watch the missile-target rendezvous process from different angles. During the missile-target rendezvous process, it can also provide repeated strike demonstrations, enter the target for 3D roaming viewing, and real-time display of target damage.

[0025] Specifically, the target damage assessment module is mainly used to realize damage effectiveness assessment. It provides automatic calculation of evaluation results such as target damage degree, target damage index, optimal aiming point, and ammunition consumption analysis based on the assessment plan. The number of fragments generated by the warhead ranges from a few hundred to a few thousand, and the number of surface units of the target model ranges from dozens to hundreds. The machine time for the calculation of projectile-target intersection is related to the number of fragments, the number of surface units, and the machine performance. For complex projectile-target relationships, the machine time for a single calculation may reach more than 10 minutes. Therefore, for the calculation of multiple projectile-target relationships, the target damage assessment module also has a batch processing mode. After defining several projectile-target relationships, the batch processing mode can be selected to import a batch of projectile-target relationships required for calculation, saving the time of importing projectile-target relationships multiple times.

[0026] Specifically, the result output module is used to display the damage effectiveness evaluation results, mainly displaying the target damage degree, target damage index, optimal aiming point, ammunition consumption analysis and other evaluation results in the form of pie charts, bar charts and line charts. When using pie charts, bar charts and line charts, the QtCharts software is used.

[0027] Those skilled in the art should understand that the present invention can be implemented in many other specific forms without departing from the spirit and scope of the present invention. Based on the embodiments of the present invention, any changes and modifications made by ordinary technicians in the field of the present invention according to the above disclosure are within the scope of protection of the claims.
