Description

Technical Field

[0001] The present invention relates to the technical field of explosion load testing, and particularly relates to a test device for energy release characteristics of an active material explosion driving device. Background Art

[0002] In recent years, air defense missiles have developed rapidly and are used to intercept multiple targets. When intercepting and killing incoming targets at the terminal stage, two technical approaches, namely direct kinetic energy collision and fragmentation killing, are commonly used. Direct kinetic energy collision is like "bullet hitting bullet". Although the hitting method is simple, it has extremely high requirements for the guidance system and the engine vector control system. Fragmentation killing is widely used because of its high efficiency in high-altitude operations, strong adaptability to the operating environment, and large killing radius under the condition of equal mass. Currently, most of the fragmentation killing uses inert fragments, and the kinetic energy penetration ability is improved by increasing the mass of a single fragment. However, this will inevitably affect the total weight of the warhead or the total number of fragments, and ultimately affect the density of fragment distribution and the mobility of the weapon. Therefore, people have begun to actively search for a new type of damage element to improve the damage ability of the warhead.

[0003] Active material, a new material that simultaneously has structural strength and chemical reaction energy release characteristics. This type of material is usually composed of two or more non-explosive solids, remains inert and does not react with each other under normal circumstances, and will rapidly release a large amount of chemical energy for rapid combustion or explosion when given sufficient mechanical, electrical, or laser stimulation. The response of this material with both strength and chemical reaction under explosion driving is different from traditional impact loading, and has the characteristics of short loading time and high strength. It can be widely used in the production of damage elements such as insensitive ammunition, active liner, and active fragments [5] to improve the damage efficiency to targets. Therefore, the technical concept of active materials has become one of the most active and important research directions in the current field of high-efficiency damage technology.

[0004] Based on the above research status, taking the active material used in the ammunition warhead shell as the research object, two different materials are selected to prepare active shells with different thicknesses, and experimental research is carried out on the energy release characteristics of the active shells under explosion driving, focusing on describing the reaction characteristics of the active material shell under explosion driving, the strengthening effect of the reaction on the shock wave damage element parameters, and analyzing the factors and influence laws of the reaction behavior of the active material shell under explosion loading. It is of great significance for deeply understanding the damage effect of the active material shell under explosion driving and will greatly promote the major engineering application of active materials as a new generation of warhead shell materials.

[0005] In the field of active material research, it is crucial to deeply understand the energy release characteristics of active material explosion-driven devices, which is of key significance for the development of many related fields. However, there are many challenges in testing the energy release characteristics of active material explosion-driven devices at present; on the one hand, existing testing equipment is difficult to accurately and flexibly adjust the support height of explosion-driven devices according to different test parameter requirements. When adjusting the height, many devices have complex operations and poor stability after adjustment, unable to meet the requirements of precise testing. For example, traditional support structures may not be able to withstand huge impact forces at the moment of explosion, resulting in deviations in test results; on the other hand, it is also difficult to effectively receive and analyze the impact generated during the explosion of explosion-driven devices. There is a lack of effective means to accurately record the damage traces of shock waves and thermal damage and accurately infer the reaction of the active material shell based on this. After being subjected to impacts multiple times, the bearing components of some existing testing equipment are severely damaged, affecting the recording of damage traces and being inconvenient to replace, greatly reducing the accuracy and continuity of testing; in addition, the cooperation between the components of existing testing equipment is often not close enough to form an efficient and collaborative working system, resulting in low overall testing efficiency and difficulty in meeting diverse testing requirements. These problems limit the research progress in the field of active materials, and there is an urgent need for a testing equipment for the energy release characteristics of active material explosion-driven devices that can solve the above problems and has high adjustability, precise testing ability, convenient component replacement, and efficient collaborative working performance.

The support mechanism 4 is used to clamp and support the explosion driving device whose energy release characteristics are to be tested, and can adjust the support height of the explosion driving device according to the requirements of the test parameters;

[0037] The support mechanism 4 includes a base 401 which is used to fixedly support the groove tube 402. The top end of the base 401 is fixedly connected with the groove tube 402 which is used to support the support rod 403, and the support rod 403 can slide up and down inside the top end of the groove tube 402. The support rod 403 is slidably connected inside the top end of the groove tube 402 and is used to fix the top plate 404. The top end of the support rod 403 is fixedly connected with the top plate 404 which is used to fix the buffer spring 405. The top end of the top plate 404 is fixedly connected with the buffer spring 405 which is used to support the groove seat 406 and can buffer the impact force generated by the groove seat 406. The top end of the buffer spring 405 is fixedly connected with the groove seat 406 which is used to fix the groove block 407. The groove block 407 is fixedly connected inside the side surface of the groove seat 406 and is used to support the clamping block 408. The inner side of the groove block 407 is slidably connected with the clamping block 408 through a return spring 5014. The clamping block 408 is used to clamp the bottom end of the outer wall of the explosion driving device. A transmission member 409 is arranged on the outer wall of the groove tube 402 and is used to drive the support rod 403 to move up and down and can clamp the support rod 403 after adjusting the support height. The base 401 is fixedly connected to the top end of the side surface of the bottom plate 1.

[0038] In this embodiment, preferably, the transmission member 409 includes a first adapter 4091 which is used to support the first connecting block 4092. The first connecting block 4092 is rotatably connected to the inner side of the first adapter 4091. The first connecting block 4092 is used to drive the vertical rod 4096 to move. A connecting rod 4093 is fixedly connected to the side surface of the first connecting block 4092. The connecting rod 4093 is used to support the counterweight 4094. The counterweight 4094 is fixedly connected to the rear end of the connecting rod 4093. The counterweight 4094 is used to reset the connecting rod 4093. A first pedal 4095 is fixedly connected to the front end of the first connecting block 4092. The first pedal 4095 is used to drive the first connecting block 4092 to rotate. The vertical rod 4096 is rotatably connected to the inner side of the first connecting block 4092. The vertical rod 4096 is used to drive the second connecting block 4097 to rotate. The top end of the vertical rod 4096 is rotatably connected to the second connecting block 4097. The second connecting block 4097 is used to drive the clamping block 4098 to move. The clamping block 4098 is rotatably connected to the inner side of the rear end of the second connecting block 4097. The clamping block 4098 is used to clamp the support rod 403. And when the second connecting block 4097 drives the clamping block 4098 to move, the support rod 403 can be driven to move synchronously. A lever 4099 is fixedly connected to the top of the front end of the clamping block 4098. The lever 4099 is used to drive the clamping block 4098 to rotate, so that the clamping of the support rod 403 by the clamping block 4098 can be cancelled, and thus the support rod 403 can slide back into the inside of the groove tube 402. A spring chuck 40910 is slidably connected to the inside of the rear end of the second connecting block 4097. The spring chuck 40910 is used to clamp the front end of the clamping block 4098. A second adapter 40911 is rotatably connected to the outside of the second connecting block 4097. The second adapter 40911 is used to support the second connecting block 4097, so that the second connecting block 4097 can rotate inside the second adapter 40911. The first adapter 4091 is fixedly connected to the bottom end of the front surface of the groove tube 402. The second adapter 40911 is fixedly connected to the top end of the front surface of the groove tube 402. A third adapter 40912 is fixedly connected to the top end of the side surface of the groove tube 402. The third adapter 40912 is used to support the clamping rod 40913. The clamping rod 40913 is rotatably connected to the inside of the third adapter 40912 through a torsion spring. The clamping rod 40913 is used to clamp the card slot formed on the side surface of the support rod 403, so as to assist the clamping block 4098 to clamp the support rod 403, and further improve the stability of the support rod 403.

[0039] In this embodiment, preferably, a groove is formed at the center of the front end of the clamping block 4098. The groove is used to clamp the spring chuck 40910, so as to clamp the clamping block 4098 and fix the clamping block 4098. The rear end of the spring chuck 40910 can be clamped inside the groove.

[0040] In this embodiment, preferably, cavities are respectively formed at the top of the front surface and the side surface of the groove pipe 402. The second adapter 40911 is fixedly connected to the outside of the cavity formed on the front surface of the groove pipe 402, and the third adapter 40912 is fixedly connected to the outside of the cavity formed on the side surface of the groove pipe 402. Through the formed cavities, a moving space for the latch 4098 and the latch rod 40913 can be reserved, so that the latch 4098 and the latch rod 40913 can latch the support rod 403.

[0041] In this embodiment, preferably, a plurality of card slots are evenly formed on the front surface and the side surface of the support rod 403. The rear end of the latch 4098 is latched inside the card slot formed on the front surface of the support rod 403, and the other end of the latch rod 40913 is latched inside the card slot formed on the side surface of the support rod 403.

[0042] In summary, when it is necessary to test the energy release characteristics of the active material explosion driving device, the prepared explosion driving device is placed inside the top of the groove base 406. Through the cooperation of the clamping block 408, the outer wall bottom end of the explosion driving device can be clamped, so as to facilitate its fixing and support. After clamping the active material shell filled with explosive, it is necessary to adjust the support height of the active material explosion driving device according to the test requirements. At this time, step on the first pedal 4095 in the transmission member 409. When stepping on the first pedal 4095 downward, the first pedal 4095 will drive the connecting block 4092 to rotate around the inner side of the adapter 4091 as the axis, so as to drive the vertical rod 4096 to move through the connecting block 4092. When the whole vertical rod 4096 slides downward, it can drive the connecting block 4097 rotatably connected to the outer side of the top end of the vertical rod 4096 to rotate downward, so as to drive the clamping block 4098 to slide upward through the connecting block 4097. Since the clamping block 4098 is clamped in the card slot opened at the front end of the outer wall of the support rod 403, when the connecting block 4097 drives the clamping block 4098 to slide upward, the support rod 403 will be driven to slide upward at the same time. After the support rod 403 slides upward, under the action of the torsion spring, the clamping rod 40913 will clamp the card slot opened on the side surface of the outer wall of the support rod 403, so as to clamp the support rod 403 that has risen a certain distance. Then cancel stepping on the first pedal 4095. Through the mutual cooperation of the counterweight 4094 and the connecting rod 4093, the connecting block 4092 can be pressed up again. When the rear end of the connecting block 4092 tilts up, the vertical rod 4096 will move upward again, so as to drive the rear end of the connecting block 4097 to tilt up, so that the clamping block 4098 originally clamped in a card slot opened at the front end of the outer wall of the support rod 403 slides downward, so that the clamping block 4098 is clamped into another card slot located at its bottom end, which is convenient for stepping on the first pedal 4095 again and through the mutual cooperation between the connecting block 4092, the vertical rod 4096, the connecting block 4097 and the clamping block 4098, so as to drive the support rod 403 to rise again. By repeatedly stepping on the first pedal 4095, the support height of the support rod 403 can be continuously adjusted, so that the explosion driving device clamped inside the groove base 406 can be supported to a corresponding height, so as to adjust the support height of the explosion driving device according to different experimental parameter requirements. When it is necessary to restore the support height supported by the support rod 403, press down the handle on the side of the clamping rod 40913, and at the same time pull the lever 4099 forward. When the lever 4099 is pulled forward, it will drive the clamping block 4098 to rotate at the same time, so as to cancel the clamping of the clamping block 4098 and the side surface of the clamping rod 40913 on the support rod 403, so that the support rod 403 can retract back into the groove tube 402 again, and then reset the support height of the support rod 403, which is convenient for adjusting the support height of the support rod 403 again.

[0043] Example Two

[0044] Please refer to Figure 1 and Figures 6-9 As shown, on the basis of Example One, a testing mechanism 5 is provided on the outer wall of the slide rail 2. The testing mechanism 5 is used to support the bearing plate 508 and can adjust the position of the bearing plate 508. In order to study the chemical reaction behavior of the active material shell under explosion drive, the impact generated when the explosion drive device explodes can be received through the testing mechanism 5. By identifying the traces on the bearing plate 508, the reaction situation of the active material shell can be inferred. The testing mechanism 5 includes a clamping member 501. The clamping member 501 is used to support the whole testing mechanism 5 and can drive the whole of it to slide on the outer wall of the slide rail 2. On one side of the top of the clamping member 501, there is a square tube 502. The square tube 502 is used to receive the insertion rod 503, and the insertion rod 503 can be inserted into or pulled out of the inside of the square tube 502. The insertion rod 503 is slidably connected to the inner side of the top of the square tube 502. The insertion rod 503 is used to fixedly support the vertical plate 506.

The diagonal brace 505 is used to support the square tube 502 and enhance the support strength of the square tube 502. The top of the insertion rod 503 is fixedly connected with a vertical plate 506. The vertical plate 506 is used to support the card frame 507. The side of the vertical plate 506 is fixedly connected with a card frame 507. The card frame 507 is used to clamp the bearing plate 508. The bearing plate 508 is clamped inside the card frame 507. The bearing plate 508 is used to receive the impact generated when the explosion drive device explodes, so as to record the shock wave damage and thermal damage generated by it.

The bottom ends of the outer walls of the plurality of guiding slide rods 5012 are slidably connected to the tooth engaging seat 5013. A return spring 5014 is fixedly connected to the outer side of the top of the tooth engaging seat 5013. The return spring 5014 is used to squeeze the tooth engaging seat 5013 so that it can be tightly clamped to the top end of the rack 3, and then the sliding seat 5011 is clamped. An arc-shaped connecting rod 5015 is fixedly connected to the center of the top end of the tooth engaging seat 5013. The arc-shaped connecting rod 5015 is used to drive the tooth engaging seat 5013 to move, so that the tooth engaging seat 5013 can cancel the mutual clamping with the rack 3. A support head 5016 is fixedly connected to the center of the front end of the outer wall of the sliding seat 5011. The support head 5016 is used to support the middle section of the outer wall of the arc-shaped connecting rod 5015, enabling the arc-shaped connecting rod 5015 to rotate around the inner side of the top end of the support head 5016. A second pedal 5017 is fixedly connected to the front end of the arc-shaped connecting rod 5015. The second pedal 5017 is used to drive the front end of the arc-shaped connecting rod 5015 to move, and thus drive the tooth engaging seat 5013 to move through the arc-shaped connecting rod 5015. The middle section of the outer wall of the arc-shaped connecting rod 5015 is rotatably connected to the inner side of the top end of the support head 5016.

[0046] In this embodiment, preferably, the sliding seat 5011 is slidably connected to the top end of the outer wall of the slide rail 2. The bottom end of the tooth engaging seat 5013 is clamped to the top end of the rack 3. The square tube 502 is fixedly connected to one side of the top end of the sliding seat 5011. The bottom end of the diagonal brace 505 is fixedly connected to the other side of the top end of the sliding seat 5011. The bottom end of the outer wall of the arc-shaped connecting rod 5015 penetrates through the center of the top end of the sliding seat 5011.

[0047] In summary, when studying the chemical reaction behavior of the active material housing under explosion drive, the test mechanism 5 of the slide rail 2 plays a key role. Its working principle focuses on the support, position adjustment of the bearing plate 508, and the reception and analysis of explosion shocks. The basic support and movement of the test mechanism 5 rely on the clamping member 501; the slide seat 5011 in the clamping member 501 can slide on the outer wall of the slide rail 2, providing a basis for the movement of the entire test mechanism 5; a plurality of guiding slide bars 5012 evenly distributed at the front and rear ends inside the slide seat 5011 not only limit the movement track of the tooth holder 5013 but also provide support for it, enabling it to slide up and down within the slide seat 5011; the return spring 5014 connected to the outer side of the top of the tooth holder 5013 continuously exerts extrusion on the tooth holder 5013, making the tooth holder 5013 tightly clamped at the top of the rack 3, realizing the fixation of the slide seat 5011; when it is necessary to move the slide seat 5011, the second pedal 5017 is operated to drive the arc-shaped connecting rod 5015 to rotate. The arc-shaped connecting rod 5015 is rotatably connected to the support head 5016. Its front end is fixedly connected to the second pedal 5017, and the middle section is supported by the support head 5016; the rotating arc-shaped connecting rod 5015 drives the tooth holder 5013 to move, making it disengage from the clamping with the rack 3, and the slide seat 5011 can then slide on the slide rail 2 to the designated position. When the second pedal 5017 is released again, the return spring 5014 makes the tooth holder 5013 re-clamp the rack 3 to fix the slide seat 5011. After the slide seat 5011 is fixed, components such as the square tube 502 and the insertion rod 503 start to play their roles; the square tube 502 is fixedly connected to one side of the top of the slide seat 5011 and is used to receive the insertion rod 503. The insertion rod 503 can be inserted into or pulled out of the square tube 502. By rotating the fastening bolt 504 inside the top of the front surface of the square tube 502, the insertion rod 503 can be locked or loosened, thereby adjusting the position of the insertion rod 503 in the square tube 502; the diagonal support rod 505 fixedly connected to the top of the side of the square tube 502 plays an auxiliary support role for the square tube 502, enhancing the support strength of the square tube 502 and ensuring its stability. After adjusting the position of the insertion rod 503, the vertical plate 506 fixedly connected to the top of the insertion rod 503 starts to play a supporting role; the clamping frame 507 fixedly connected to the side of the vertical plate 506 is used to clamp the bearing plate 508. The bearing plate 508 is one of the key components of the entire test mechanism 5 and is used to receive the shock generated when the explosion driving device explodes; when the explosion occurs, the bearing plate 508 is impacted, and relevant traces of shock wave damage and thermal damage are recorded.Subsequently, by identifying these traces on the bearing plate 508, the reaction of the active material housing under explosion driving can be inferred. Through the close cooperation of various components of the entire slide rail 2 test mechanism 5, from the clamping member 501 to achieve the movement and fixation of the mechanism, to the adjustment of the height position of the bearing plate 508 by components such as the square tube 502 and the insertion rod 503, and then to the bearing and trace recording of the explosion impact by the bearing plate 508, it provides an effective means for studying the chemical reaction behavior of the active material housing under explosion driving, enabling scientific researchers to deeply understand the reaction characteristics of the active material housing through the analysis of these data and traces. At the same time, since the bearing plate 508 is clamped inside the card frame 507, when the bearing plate 508 is damaged multiple times and affects its recording of the damage traces of the explosion impact it bears, the bearing plate 508 can be replaced conveniently and quickly to maintain the accuracy of the damage trace recording of the bearing plate 508.;

[0048] Embodiment 3

[0049] Please refer to Figures 1-9 As shown, by combining Embodiment 1 and Embodiment 2, this embodiment is obtained. This device is mainly used to test the energy release characteristics of the active material explosion driving device. Its core consists of a support mechanism 4 and a test mechanism 5, which cooperate to complete the test task. The main body of the device is built on the base plate 1, providing a stable support and installation foundation for each component;

[0050] The support mechanism 4 is responsible for clamping and supporting the explosion driving device and can adjust the support height according to the test parameters. Its structure includes a base 401, a groove tube 402, a support rod 403, a top plate 404, a buffer spring 405, a groove seat 406, a groove block 407, a clamping block 408, and a transmission member 409;

[0051] The base 401 is firmly connected to the side of the base plate 1 and supports the groove tube 402. The support rod 403 can slide up and down inside the groove tube 402. The top of the support rod 403 is connected to the top plate 404. The buffer spring 405 on the top plate 404 is connected to the groove seat 406. The groove block 407 on the side of the groove seat 406 is connected to the clamping block 408 through a return spring 5014 for clamping the explosion driving device;

[0052] The transmission member 409 is the key to adjusting the support height, and it includes the first adapter 4091, the first connecting block 4092, the connecting rod 4093, the counterweight 4094, the first pedal 4095, the vertical rod 4096, the second connecting block 4097, the clamping block 4098, the lever 4099, the spring chuck 40910, the second adapter 40911 and the third adapter 40912. When the height needs to be adjusted, step on the first pedal 4095 to drive the first connecting block 4092 to rotate around the first adapter 4091, thereby moving the vertical rod 4096. The vertical rod 4096 drives the second connecting block 4097 to rotate, and the second connecting block 4097 pushes the clamping block 4098 to slide upward. Since the clamping block 4098 is clamped with the card slot at the front end of the outer wall of the support rod 403, the rising of the clamping block 4098 will drive the support rod 403 to rise synchronously. At this time, under the action of the torsion spring, the clamping rod 40913 clamps the card slot on the side of the support rod 403 to assist in fixing the support rod 403. After releasing the first pedal 4095, the cooperation of the counterweight 4094 and the connecting rod 4093 resets the first connecting block 4092. The vertical rod 4096 moves upward, the rear end of the second connecting block 4097 tilts up, and the clamping block 4098 slides down to the next card slot. Repeatedly stepping on the first pedal 4095 can continuously adjust the height of the support rod 403 to meet different test requirements. If you want to restore the height of the support rod 403, press the handle on the side of the clamping rod 40913 and pull the lever 4099 to release the clamping of the support rod 403 by the clamping block 4098 and the clamping rod 40913, and the support rod 403 will retract into the trough pipe 402;

[0053] The test mechanism 5 is installed on the slide rail 2, and its main function is to support the bearing plate 508 and adjust its position to receive the impact generated when the explosive driving device explodes, so as to infer the reaction of the active material shell. The test mechanism 5 includes the clamping member 501, the square pipe 502, the inserting rod 503, the fastening bolt 504, the inclined strut 505, the vertical plate 506, the clamping frame 507 and the bearing plate 508;

[0054] The clamping member 501 is the basis for the movement and fixation of the test mechanism 5. It is composed of the slide seat 5011, the guiding slide rod 5012, the tooth seat 5013, the return spring 5014, the arc-shaped connecting rod 5015, the support head 5016 and the second pedal 5017. The slide seat 5011 can slide on the slide rail 2. The guiding slide rod 5012 inside it limits the movement track of the tooth seat 5013 and provides support. The return spring 5014 on the top of the tooth seat 5013 makes it tightly clamped at the top of the rack 3. Fix the slide seat 5011. When it is necessary to move the slide seat 5011, step on the second pedal 5017 to drive the arc-shaped connecting rod 5015 to rotate around the support head 5016, so that the tooth seat 5013 is disengaged from the clamping with the rack 3, and the slide seat 5011 can slide on the slide rail 2. After reaching the designated position, release the second pedal 5017, and the return spring 5014 makes the tooth seat 5013 tightly clamp the rack 3 again to fix the slide seat 5011;

[0055] After the slide 5011 is fixed, the square tube 502, the plug rod 503 and other components begin to play a role. The square tube 502 is fixed to one side of the top of the slide 5011 to receive the plug rod 503. The plug rod 503 can be inserted or pulled out of the square tube 502. The plug rod 503 can be locked or loosened by rotating the fastening bolt 504 to adjust the position of the plug rod 503. The diagonal support rod 505 on the side of the square tube 502 enhances the supporting strength of the square tube 502. After the position of the plug rod 503 is adjusted The vertical plate 506 at the top of the plug rod 503 supports the card frame 507 on the side. The card frame 507 is used to clamp the bearing plate 508. The bearing plate 508 is a key component of the test mechanism 5, which is used to bear the impact generated by the explosion, record the shock wave damage and thermal damage traces, and then infer the reaction of the active material shell by identifying these traces. In addition, the bearing plate 508 is clamped in the card frame 507, which is convenient for replacement when it is damaged multiple times and affects the trace recording, so as to ensure the accuracy of the test;

[0056] When testing the energy release characteristics of the active material explosion drive device, firstly, the prepared explosion drive device is placed on the top of the slot seat 406 and fixedly supported by the clamping action of the clamp block 408. Then, according to the test requirements, the support height of the explosion drive device is adjusted by using the transmission member 409 of the support mechanism 4 to meet the requirements of different experimental parameters.

[0057] After the support height adjustment is completed, the slide 5011 is moved to a suitable position and fixed by using the clamping member 501 of the test mechanism 5, and then the height of the bearing plate 508 is determined by adjusting the position of the insertion rod 503 in the square tube 502, and then the bearing plate 508 is clamped in the clamping frame 507;

[0058] When the explosion-driven device explodes, the impact generated is received by the carrier plate 508, which records the shock wave damage and thermal damage traces. Finally, the researchers infer the chemical reaction behavior of the active material shell under the explosion drive by identifying the traces on the carrier plate 508, thereby gaining a deep understanding of the energy release characteristics of the active material.

[0059] Through the coordinated work of the support mechanism 4 and the test mechanism 5, the device can efficiently and accurately complete the test of the energy release characteristics of the active material explosion drive device, providing strong data support and experimental guarantee for related research. The close cooperation of various components and the adjustable and replaceable design features make the equipment have good adaptability and reliability, meeting the diverse testing needs. Whether in basic research or practical applications, this test equipment plays an important role and promotes the research and development in the field of active materials.
