The Application of Senther Technology Products in the Light Weapons Testing and Testing Industry

1. Industry background in the field of light weapon testing and testing

Guns are the second life of soldiers, and their performance directly affects the effectiveness of combat. From blueprint design to equipping troops, performance testing is an important link that determines whether a gun can smoothly move from the factory to the battlefield. From handguns to artillery, any new weapon or equipment that needs to enter our army's combat sequence must undergo a series of detailed and complex experiments and finalization in order to obtain a "life permit"Imagine, if a gun can fire ten thousand bullets in normal times and "give up" under harsh conditions, how can soldiers use such a gun with confidence? For this reason, in recent years, the military representative office and testing and testing center have continuously increased the inspection standards for guns, whether the dropping of guns during marching will affect their effectiveness, whether the safety mechanism of guns is secure after long-term combat, and whether the safety will be reduced after multiple disassembly and decomposition. These "physical inspection" projects have become more and more perfect.

So, what kind of testing and evaluation should light weapons undergo before they can be installed? What does an extreme testing environment look like?

In recent years, in order to meet the new requirements of our military's equipment construction, based on the completion of the Army's light weapon testing and appraisal tasks, this target range has actively expanded the scope of testing technology services according to the special needs of the Navy, Army Aviation and other branches of the military for light weapon testing.More than 10 scientific research projects, including environmental adaptability and electromagnetic compatibility, have been completed by the range technology personnel. A laboratory capable of simulating 8 extreme climates has been built, and a batch of advanced testing equipment, such as optical comprehensive testing systems, have settled in the range.

2. The main purpose and problems to be solved in the testing and testing of light weapons

(1) Fatigue testing of each structural component of the firearm on a vibration and impact test bench before assembly; verifying the ability of each component to resist fatigue;

(2) Fatigue verification of high vibration on a vibration table after the assembly of firearms; impact verification test of simulated high-altitude drop after the assembly of light weapons;

(3) Conduct a strong impact test at a temperature of 45 degrees Celsius to verify the stability of light weapons suitable for high-temperature environments;

(4) Shooting verification tests at temperatures below 45 degrees Celsius; verifying the performance feasibility of light weapons in low-temperature environments;

(5) Simulate reliability tests under heavy dust conditions, where a large amount of smoke and dust is produced under the attack of tanks and planes. In this case, it is necessary to verify the reliability and stable performance of light weapons in working in dusty environments;

(6) Shooting tests in rainy environments to verify the normal firing and use of firearms under fully wet conditions;

(7) Finally, conduct live fire testing and shooting verification experiments, analyze the lethality of light weapons based on the impact feedback on your fast dummy body;

(8) Verification testing of bullets of different calibers with matching firearms, combined with data collection and feedback from dummies, impact decks, and targets, to verify the performance of bullets in terms of impact force, penetration force, wind resistance, etc;

3. Different types of sensors involved in light weapon testing experiments

(1) Attitude acceleration sensor, installed inside the verification warhead, analyzes the changes in acceleration and deceleration, analyzes the data of structural wind resistance, confirms the accuracy of hitting the target, and improves and optimizes the design parameters of the warhead, projectile body, and propellant capacity through experimental data;

(2) Impact acceleration sensor, installed inside the verification warhead, analyzes the acceleration information when impacting the target and dummy body; Analyze penetration, lethality, accuracy, etc;

(3) A miniature three-axis vibration sensor is used to test the structural fatigue performance of each structural component of firearms on a fatigue test bench, with high vibration and high frequency. Its function is to verify the durability performance of each component;

(4) A water droplet type single axis vibration sensor is used to test the structural fatigue performance of each small structural component of firearms on a fatigue test bench, with high vibration and high frequency. Its function is to verify the durability performance of each component;

(5) The recoil impact acceleration sensor tests the feedback of the recoil impact acceleration value of the gun stock during bullet firing, verifies the impact force on the human body, optimizes structural design, and increases lethality while making users more comfortable and reliable;

(6) Multidimensional firearm fatigue verification sensors are used to test the overall long-term stability performance of firearms under different high and low temperatures, sand and dust, rain and other environments after assembly, ensuring that there are no incidents of "leaving behind" or "dropping chains" in the hands of soldiers.

5. Finally, using the internet, a journalist asked the stationed military representative of a certain unit a question to end it; What kind of gun can make officers and soldiers use it with peace of mind? The stationed military representative humorously replied, "A gun that doesn't 'drop its chain' on the battlefield. If it doesn't 'drop its chain', it means the gun's performance is stable.". Whether the shooting life of a gun can meet the standard is an important indicator that affects its stability in use, and it is also an essential "physical examination" item for the gun in the testing and testing center..
