Description

Technical Field

[0001] The present invention relates to the technical field of performance evaluation of military and police protective equipment, in particular to the field of facial protective equipment, and specifically refers to a target system for evaluating the impact resistance performance of facial protective equipment. Background Art

[0002] In the military and police field, the performance of facial protection equipment is directly related to the life safety and mission execution capabilities of personnel. With the emergence of new weapons in modern warfare and law enforcement operations, and the increase of non-traditional security threats, the potential risk of facial injury is also increasing. These risks include high-speed shrapnel, explosion shock waves, close-range explosives, chemical splashes, etc., each of which poses different challenges to protective equipment. Therefore, it is crucial to conduct accurate and comprehensive impact resistance performance evaluation of military and police facial protection equipment.

[0003] The existing military and police facial protection equipment assessment technology has the following shortcomings:

[0004] Low structural simulation: Traditional target systems fail to fully consider the complex physiological structure of the face during design, such as the hierarchical structure of skin, soft tissue and bones and their absorption and dispersion of impact energy, resulting in a large difference between the evaluation results and the protective effect under actual combat conditions;

[0005] Outdated sensor technology: The number and location distribution of sensors in the existing target system are unreasonable, which cannot fully capture the dynamic response of key parts of the face under impact, limiting the understanding of local damage mechanisms;

[0006] Rigid fixation of targets: lack of a flexible target fixation platform, the angle and position of the target cannot be adjusted according to test requirements, affecting the comprehensiveness and flexibility of the evaluation;

[0007] Limited data processing capabilities: The integration of data acquisition systems and analysis software is not high, making it difficult to achieve fast and accurate data analysis, affecting the efficiency and depth of the assessment.

[0008] The assessment of facial injuries caused by weapons and equipment is another important aspect. On modern battlefields, facial injuries caused by weapons such as explosives, high-speed fragments and projectiles are one of the common types of combat injuries. In order to reduce such injuries, it is necessary to conduct in-depth research on the impact effects of weapons on the head and face, and effective assessment tools are the basis of this research. However, existing assessment methods often find it difficult to accurately simulate the actual scenarios of weapon impact, especially in terms of the transient response of impact force and the assessment of facial tissue damage.

[0009] In view of the above background, there is an urgent need for a new target system for evaluating the impact resistance of facial protective equipment. It should have a highly realistic facial structure model, intelligent sensor layout, flexible target fixing platform, and efficient data collection and analysis capabilities to meet the high requirements of the military and police field for facial protective equipment and weapon injury assessment. This system can not only improve the accuracy of the assessment, but also accelerate the development of new protective technologies and provide more reliable protection for frontline personnel.

The system mainly includes three core parts: facial target assembly, data acquisition and processing module, and target fixing platform.

[0072] 1. Facial target component 10

[0073] The facial target assembly 10 is the core of this technical solution. It simulates the skin, soft tissue, bones and other structures of the human face, and is embedded with a sensor system to capture mechanical data during the impact process. Specifically, it includes:

[0074] Bionic soft tissue layer 12: It contains soft tissue layers such as skin, fat and muscle, and is made of SEBS or silicone material with a specific proportion, aiming to simulate the softness, elasticity, wear resistance and shock absorption ability of human epidermis. The material of this layer is carefully selected, processed and arranged to ensure stable physical properties during long-term testing.

[0075] Bionic skull structure 20: It is composed of a brain skull, a facial skull and a brain-neck connection component. The bionic bone material is made of specific nylon glass fiber, alloy or other materials to simulate the mechanical response characteristics of the skull;

[0086] Data storage unit: used to store received data for subsequent analysis and processing.

[0087] Data Analysis Unit: Advanced algorithms and models are used to process and analyze data to generate detailed reports on the impact resistance of facial protective equipment. The software can automatically identify abnormal data and trends, providing valuable reference information for evaluators.

[0088] The technical solution will be further described in detail below:

[0089] 1. System composition and construction

[0090] 1. Detailed construction of facial target component 10

[0091] Bionic skin layer 11: Bionic skin is made of SEBS (styrene-ethylene-butylene-styrene block copolymer) or silicone, with a concentration of 30%-50% SEBS, or 30A silicone, mixed through a special process. The thickness of this layer is about 2mm, and the surface is specially treated to simulate the texture and friction coefficient of human skin to ensure authenticity during the test.

[0092] Bionic soft tissue layer 12: located below the bionic skin layer, with a thickness of about 3 mm, using SEBS gel with a SEBS concentration of 12.5%-20%, and a solvent of mineral oil, simulating soft tissues such as fat and muscle to provide better elasticity and impact absorption.

[0093] Facial sensor system 30: Seven high-precision sensors are embedded in the bionic skull, including four pressure sensors and three impact force sensors. These sensors are located at key locations of the frontal bone, eyes (one on each side), cheekbones (one on each side), nasal bones, and jaws. The sensor collection surface is customized according to the height of the facial bone protrusions to ensure accurate capture of the force conditions of each part. The sensors are connected to the data acquisition and processing system through fine wiring.

[0094] Headform base 40: Made of high-strength aluminum alloy, it is precision-processed by CNC and anodized on the surface to improve wear resistance and corrosion resistance. The base is designed with precise sensor mounting slots and fixtures to ensure the accuracy and stability of sensor installation. The base bottom is designed with a standard mounting interface for easy connection with the target fixing platform.

[0095] 2. Data acquisition and processing module 60

[0096] The system includes a real-time data transmission unit, a data storage unit and a data analysis unit. The real-time data transmission unit is connected to the facial sensor system wirelessly or wired to ensure high-speed and stable data transmission. The data storage unit uses a high-capacity SSD hard drive to store a large amount of test data. The data analysis software has powerful data processing and analysis capabilities, can automatically identify sensor signals, calculate key parameters such as impact force and pressure, and generate detailed test reports.

[0097] 3. Target fixation platform 50

[0098] The platform adopts a solid steel structure frame and is covered with non-slip material. The platform has built-in precision electric motors and microprocessor control systems, and multi-axis adjustment (including horizontal movement, vertical lifting, pitch and yaw adjustment) can be achieved through the control panel or remote control. The adjustment accuracy can reach 0.1 degrees, ensuring the precise positioning of the target at different test angles. The platform is also equipped with a locking mechanism to ensure the stability of the target during the test.

Start the test program and use the specified impact device to perform an impact test on the protective equipment. At the same time, the data acquisition and processing module 60 records and processes the sensor data in real time.
