Description

Technical Field

[0001] This application relates to a testing device applicable to the fields of dynamic testing or ammunition power testing. Background Technology

[0002] In the field of traditional small-mass impact testing, the main focus is on test objects with relatively small masses, such as fragments. The testing requires assessing the changes in the test object's motion, mass loss, and deformation of both the test object and the target plate before and after impacting a target plate under different angles and velocities. Traditional testing equipment can only impact the target plate at a fixed angle and cannot effectively control the impact position of the test object on the target plate. This results in uncontrollability in the testing and a significant waste of resources. Summary of the Invention

[0003] In view of this, embodiments of this application aim to provide a testing device, the device comprising:

[0004] The test frame is used to support the sheller and the target plate;

[0005] The ejector has a first through hole for a test subject fired from a ballistic gun to pass through, so that the test subject is fired at the target plate;

[0006] A target plate is disposed on one side of the shell-removing device for the test subject to fire at, and for fixing the test subject at the firing position corresponding to the test subject firing at the target plate.

[0007] A first adjustment component is disposed on the test frame and corresponds to the shell remover. It is used to adjust the height of the first through hole on the shell remover so that the first through hole is at the same horizontal line as the muzzle of the ballistic gun.

[0008] The second adjustment component is disposed on the test frame and corresponds to the target plate, and is used to adjust the impact position of the target plate relative to the test object.

[0011] The second adjustment structure, connected to the first adjustment structure, is used to adjust the height of the first adjustment structure to adjust the impact height of the target plate relative to the test body.

[0012] In the above scheme, the first adjustment component is also used to adjust the aperture parameter of the first through hole so that the diameter of the first through hole is greater than the diameter of the test body and less than the diameter of the spring corresponding to the test body.

[0014] A recycling device is located on one side of the test frame and is used to recycle the test subject.

[0015] In the above solution, the device further includes:

[0016] The third adjustment component is connected to the recycling device and is used to adjust the placement of the recycling device relative to the test frame.

[0017] In the above scheme, the recycling device includes:

[0018] The housing has a cavity for containing a recovery liquid, which is used to buffer the impact velocity of the test subject in order to recover the test subject.

[0026] An image acquisition device is installed on one side of the test frame and is used to acquire frame images during the process of the test object impacting the target plate.

[0027] In the above solution, the device further includes:

[0028] The processing device, connected to the image acquisition device, is used to determine the movement distance and movement path of the test object within a preset time based on the frame image, and to determine the launch speed of the test object during the impact of the test object on the target plate based on the movement distance and the movement path.

[0029] The testing equipment provided in this application, by setting a first adjustment component and a second adjustment component on the test frame, can adjust the position and angle of the shell remover and the target plate relative to the test body.

[0038] It should be noted that the terms "first," "second," and "third" used in the embodiments of this application are merely used to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted. It should be understood that the objects distinguished by "first," "second," and "third" can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.

[0039] Figure 1 This is a schematic diagram of the structural composition of the testing equipment in this application. Figure 1 , Figure 2 This is a schematic diagram of the structural composition of the testing equipment in this application. Figure 2 , Figure 3 This is a schematic diagram of the structural composition of the testing equipment in this application. Figure 3 ;like Figures 1 to 3 As shown, the device includes: a test frame 10, a sheller 20, a target plate 30, a first adjustment component 40, and a second adjustment component 50. The test frame 10 is formed of a rigid material and is used to support the sheller 20 and the target plate 30. The test frame 10 has multiple triangular support parts to improve the stability of the test frame 10. The discarding device 20 has a first through hole 201 for separating the test subject from the sabot fired from the ballistic gun, and allowing the test subject to pass through the first through hole 201 to be fired at the target plate 30. The target plate 30 is disposed on one side of the discarding device 20 for the test subject to be fired at, and fixes the test subject at the firing position corresponding to the test subject firing at the target plate 30. A first adjustment component 40 is disposed on the test frame 10, corresponding to the discarding device 20, for adjusting the height of the first through hole 201 on the discarding device 20 so that the first through hole 201 is at the same horizontal line as the muzzle of the ballistic gun. A second adjustment component 50 is disposed on the test frame 10, corresponding to the target plate 30, for adjusting the impact position of the target plate 30 relative to the test subject.

[0040] Here, the ballistic gun can be considered part of the testing equipment or independent of it; no specific limitation is made here.

[0041] Here, the type of test subject is not limited. It can be a test subject fired from a ballistic gun, such as a bullet or a small object such as fragments of the warhead on a bullet.

[0042] In this application, the test frame 10 may have multiple second through holes 101; the shell remover 20, the target plate 30, the first adjustment component 40, and the second adjustment component 50 are all fixed to the test frame 10 by bolts (or fasteners or other components) passing through the second through holes 101. By providing multiple second through holes 101 on the test frame, the multi-angle impact requirements of the test object can be met.

[0043] In this application, a pulley 102 may also be provided on the test frame 10. The pulley 102 can be used to adjust the current position of the test frame 10 so that the test object can more accurately hit the target plate on the test frame 10.

[0044] In this application, the first adjustment component 40 is further used to adjust the aperture parameter of the first through hole 201, so that the diameter of the first through hole 201 is larger than the diameter of the test body and smaller than the diameter of the sabot corresponding to the test body. This allows for the satisfaction of testing requirements for different test bodies, enabling test bodies of different sizes to pass smoothly and impact the target plate 30, while the sabot can impact the discarding sabot and separate from the test body. Here, selecting a sabot that matches the size of the test body achieves good gas sealing within the ballistic gun, resulting in a more stable and controllable firing rate.

[0045] Here, the specific structure of the first adjustment component 40 is not limited, as long as it can adjust the height and diameter of the first through hole 201 on the sheller 20. For example, when the first adjustment component 40 can adjust the height of the first through hole 201 on the sheller 20, the first adjustment component 40 can be a shim. When the first adjustment component 40 can adjust the diameter of the first through hole 201 on the sheller 20, the first adjustment component 40 can be a knob.

[0046] In this application, the second adjustment component 50 includes: a first adjustment structure 501 and a second adjustment structure 502, wherein one end of the first adjustment structure 501 is connected to the test frame 10 and the other end is connected to the target plate 30, and is used to adjust the impact angle of the target plate 30 relative to the test body; one end of the second adjustment structure 502 is fixedly connected to the test frame 10 and the other end is connected to the first adjustment structure 501, and is used to adjust the height of the first adjustment structure 501 so as to adjust the impact height of the target plate 30 relative to the test body.

[0047] Here, the specific structure of the second adjustment component 50 is not limited, as long as it can adjust the impact position of the target plate 30 relative to the test object. Figure 1 As shown, the first adjustment structure 501 and the second adjustment structure 502 can be gaskets.

[0048] In this application, the device also includes a recovery device 60, disposed on one side of the test frame 10, for recovering the test subject. For example, the recovery device 60 can be disposed near the target plate 30 so as to accurately recover the test subject on the target plate.

[0049] Here, the device may also include a third adjustment component (not shown in the figure), connected to the recovery device 60, for adjusting the placement of the recovery device 60 relative to the test frame 10. For example, the third adjustment component may be a slide rail, pulley, or other displacement device.

[0050] like Figure 1As shown, the recovery device 60 can specifically be a water tank, including a tank body 601 and a fourth adjustment component (not shown in the figure). The tank body 601 has a accommodating cavity 602 for accommodating the recovery liquid, which is used to buffer the impact velocity of the test subject in order to recover the test subject. The fourth adjustment component is disposed on the tank body 601 for adjusting the capacity of the recovery liquid in the tank body 601.

[0051] Here, the specific structure of the fourth regulating component is not limited; for example, it can be a control valve or other component that can control the amount of liquid in the tank.

[0052] This application enables the non-destructive recycling of test subjects by setting up a recycling device, thereby reducing secondary damage to the test subjects.

[0053] In this application, the device may further include a gun holder 70 and a ballistic gun 80, wherein the gun holder 70 is disposed on one side of the test frame 10 for supporting the ballistic gun 80; the ballistic gun 80 has a muzzle 801, which corresponds to the extractor 20 and the target plate 30 for launching the test object.

[0054] Here, the ballistic gun 80 can also control the firing speed of the test subject, which can meet the firing requirements of test subjects with different speeds.

[0055] In one example, the distance between the ballistic gun 80 and the discarding device 20 can be 600mm, and the height above the ground can be 1155mm.

[0056] like Figures 1 to 3 As shown, the device also includes an image acquisition device 90, which is disposed on one side of the test frame and is used to acquire frame images of the test object before and after impacting the target plate 30 during launch, so as to obtain the state changes of the test object before and after impacting the target plate.

[0057] Here, the image acquisition device 90 can specifically be a high-speed camera designed for capturing fast-moving objects.

[0058] In this application, the device also includes a processing unit (not shown in the figure), which can be connected to the image acquisition device 90, for determining the movement distance and movement path of the test object within a preset time based on the frame image, and for determining the launch speed of the test object during the impact of the test object on the target plate 30 based on the movement distance and the movement path.

[0059] The testing equipment provided in this application, by setting up a test frame with multiple adjustment components, allows for lateral and longitudinal angle adjustments to the target plate and decapsulator of the test phase. This enables the test subject to impact the target plate at different angles, while also improving the reusability of the same target plate and reducing the cost of replacing it. The adjustment method of this application is simple and convenient, requiring no learning curve.

[0060] Figure 4 This is a schematic diagram of the motion state of the test object before and after impacting the target plate in this application, as shown below. Figure 4 As shown, the velocity of the test object before and after impact with the target plate can be obtained by measuring the distance traveled by the test object towards the target plate within a certain time. The angle between the trajectory of the test object before and after impact with the target plate can be determined by measuring the distance traveled by the test object before and after impact with the target plate. and The angle between the motion path of the test object before and after impacting the target plate and the normal of the target plate can be obtained. and In a certain test state during the experiment, as shown Figure 5 As shown. The test object's state before and after impacting the target plate.

[0061] Compared with traditional impact testing equipment, the testing equipment provided in this application can realize multi-angle and multi-directional testing of the test object on the same target plate, making the testing process more precise and controllable, and significantly improving the effective utilization rate of the target plate and the multi-angle testing requirements of the test object.

[0062] The above description is merely a specific implementation of this application, but the scope of protection of this application is not limited thereto.
