Problems solved by technology

[0003] Since the surface of the ceramic composite armor plate is severely damaged after being hit by a projectile, the existing technology does not solve the problem of determining the impact point of the ceramic composite armor, and cannot establish the correspondence between the ballistic performance test results and the ceramic regions with different protective performance. It is also impossible to classify and evaluate the ballistic performance of different ceramic regions

Embodiment 1

[0035] The technical solution involved in the present invention is described in detail by taking the ballistic experiment system with a shooting distance of 5m (B) that meets the requirements of GB / T 32497-2016 as an example. The test bullet is a 7.62mm armor-piercing incendiary bomb of Type 53. The tough thin steel plate is used as the target plate for verification.

[0036] The structure of the test device is attached figure 1 As shown, including the ballistic gun and the trigger screen, cut-off screen, first fixed frame, second fixed frame, and target frame arranged on the ballistic line in sequence, the trigger screen and the cut-off screen are all connected with the timer; A support frame 7 with a horizontal slide rail 6 is arranged between them. The horizontal slide rail 6 is parallel to the ballistic line. The two fixed frames are installed on the slide rails in sequence. 6 Move, the centers of the two vector papers are placed on the expected ballistic line, and paral...

Embodiment 2

[0044] The structure and test conditions of the ballistic test system are the same as those in Example 1. The distance A between the first vector paper and the gun muzzle is 3.5m, and the second fixing frame is a foldable resettable structure.

[0045] After installing the positioning test target board during the test, put down the second fixed frame (with the second vector recording paper) and move the second vector recording paper away from the ballistic line to shoot and measure the first test projectile. The second fixed frame (with the second vector recording paper) is reset, and the second fixed frame is put down after the test target board is installed to shoot and measure the second test projectile. Repeating this can use one standard projectile to carry out multiple projectile tests. The following table lists the test results of the three test rounds.

Embodiment 3

[0048] The structure and test conditions of the ballistic test system are the same as those in Example 1. A position-adjustable laser locator is installed above the first fixed frame, and the distance A between the first vector paper and the muzzle is 2.5m.

[0049] During the test, record the ballistic parameters of the reference projectile, and adjust the laser locator to locate the bullet hole b on the second vector paper and lock it, remove the second vector paper, use the laser locator to locate the target shooting point, adjust the installation position of the target plate, and install After the target plate, the test projectile is shot and measured, so that one standard projectile can be used for multiple projectile tests by repeating this. The following table lists the test results of the three test rounds.

Abstract

The invention belongs to the technical field of testing. By setting a pair of ballistic line vector recording devices with appropriate intervals in parallel in the conventional ballistic test system, using the principle of similarity ratio, taking the first bullet as the reference, and using the impact point and deviation value of the first bullet to accurately locate the impact point of the test bullet on the target plate . The ballistic test device related to the present invention is a ballistic test system including a ballistic gun, a speed measuring device, and a target frame, and also includes a pair of vector recording papers arranged in parallel between the speed measuring device and the target frame (9), and the second vector The recording (5) paper is close to the bomb receiving surface of the target board; the vector paper is parallel to the target surface of the velocity measuring device trigger screen (10) and cut-off screen (11). The device has the advantages of simple structure, strong designability, good reliability, simple operation and easy control of the method for measuring the impact point, high positioning accuracy of the impact point, and is suitable for sub-area protection performance evaluation of easily broken or irregular bullet holes.

Description

technical field [0001] The invention belongs to the technical field of testing, and relates to a device and a method for testing ballistic terminal effects. Background technique [0002] The ceramic composite armor structure includes a crack arrest layer, a ceramic layer, an adhesive layer and a backing plate. The ceramic layer is generally formed by splicing multiple pieces of ceramics. The splicing structure of the ceramic layer forms different protection areas in the plane: the ceramic center area, the seam area and the corner area. Research shows that, for ceramic composite armor, there is a large difference in the ballistic performance of different protection areas. Therefore, it is very important to test the ballistic performance of different regions for the performance evaluation of ceramic composite armor. [0003] Since the surface of the ceramic composite armor plate is severely damaged after being hit by a projectile, the existing technology does not solve the ...
