[0032] Combine the following Figure 1-Figure 10 The vibration testing apparatus provided by the present invention is described.

[0033] Reference Figures 1 to 3 A vibration testing device provided by an embodiment of the present invention includes a vibration table 100, a vibration chamber 200, a control device 400 and a plurality of monitoring and adjustment devices 500. The vibration table 100 has a vibration function cavity 110 inside, and a vibration generator 140 is arranged inside the vibration function cavity 110; the vibration bin 200 is fixedly or detachably connected to the top of the vibration table 100, and a vibration test cavity 219 is arranged inside the vibration bin 200; the control device 400 is fixedly or detachably arranged inside the vibration test cavity 219, and the control device 400 includes a limit seat 410 and a sliding push component 420, the limit seat 410 is connected to the vibration generator 140, and the sliding push component 420 is arranged on the limit seat 410; a plurality of monitoring and adjusting devices 500 are spaced and detachably arranged inside the vibration test cavity 219, and the monitoring and adjusting devices 500 are electrically connected to the sliding push component 420; wherein the monitoring and adjusting devices 500 are used to detect and adjust the position of the sample, and transmit the position information of the sample to the sliding push component 420, and the sliding push component 420 is used to cooperate with the monitoring and adjusting device 500 to adjust the position of the sample to within the target range.

[0034] Specifically, when the vibration generator 140 is started, a preset vibration mode will be generated in the vibration test chamber 219, and the sample may be displaced under the effect of the vibration. During the vibration process, the monitoring and adjustment device 500 distributed in the vibration test chamber 219 will collect the position data of the sample in real time, analyze the position information of the sample, and then adjust the position of the sample; at the same time, the monitoring and adjustment device 500 can also transmit this position information to the sliding push component 420, and the sliding push component 420 calculates according to the received position information and cooperates with the monitoring and adjustment device 500 to adjust the sample to the expected position.

[0035] In the above structure, the vibration table 100 is the base of the whole system, which contains a vibration function cavity 110 inside, and the vibration function cavity 110 is provided with a vibration generator 140. The vibration generator 140 is a key component for generating vibration, which can simulate the vibration in the real environment during the experiment. The vibration bin 200 is installed on the vibration table 100, and has a vibration test cavity 219 inside. The vibration test cavity 219 is used to place the samples to be tested, and it is also the working place of the monitoring and adjustment device 500 and the control device 400. Multiple monitoring and adjustment devices 500 are distributed in the vibration test cavity 219 at intervals up and down, which can not only detect the position change of the sample, but also adjust the position of the sample.

[0036] At the same time, the monitoring and adjusting device 500 is electrically connected to the sliding push assembly 420, and the detected position information can be fed back to the sliding push assembly 420 in a timely manner. After receiving the position information detected by the monitoring and adjusting device 500, the sliding push assembly 420 adjusts the position of the sample to prevent its position from deviating too much during the vibration process. The control device 400 is located inside the vibration test chamber 219, and is mainly composed of a limit seat 410 and a sliding push assembly 420. The limit seat 410 can be directly connected to the vibration generator 140, and the sliding push assembly 420 is installed on the limit seat 410. The limit seat 410 is used to carry the sample, and transmit the vibration to the limit seat 410 through the vibration generator 140, thereby simulating the vibration of the sample.

[0037] The present invention sets up a closed-loop control system, and simulates the vibration of the sample through the vibration generator 140. In addition, the real-time monitoring of the position of the sample is realized through the monitoring and adjusting device 500, and the control device 400 and the monitoring and adjusting device 500 cooperate with each other to adjust the position of the sample, thereby being able to accurately control the position of the sample, reduce the deviation caused by vibration, ensure that the position of the sample in the entire experimental process remains within the set target range, avoid the influence of the experimental data due to the sample being out of position, and ensure the consistency and accuracy of the experimental data.

[0038] Reference Figure 6 In some embodiments of the present invention, the monitoring and adjusting device 500 includes a carrying ring 510 and a monitoring and adjusting component 520. The carrying ring 510 is provided with a first airflow channel, the first airflow channel is connected to one end of a second airflow channel provided in the vibration chamber 200, and the other end of the second airflow channel is connected to a high-pressure air pump 216; there are multiple monitoring and adjusting components 520, and the multiple monitoring and adjusting components 520 are detachably installed on the inner wall of the carrying ring 510 at intervals, and the multiple monitoring and adjusting components 520 are surrounded by the periphery of the sample. Among them, the monitoring and adjusting component 520 includes an airflow nozzle 523, the airflow nozzle 523 is connected to the first airflow channel, and the airflow nozzle 523 adjusts the position of the sample through airflow.

[0039] Specifically, when the vibration experiment begins, the vibration generator 140 generates a predetermined vibration mode in the vibration test chamber 219 to simulate the vibration conditions in actual working conditions. The sample is placed in the vibration test chamber 219, and as the vibration occurs, the sample may be displaced. At this time, the multiple monitoring and adjustment components 520 in the monitoring and adjustment device 500 begin to play a role. Each monitoring and adjustment component 520 includes an air flow nozzle 523, which is connected to the first air flow channel inside the carrying ring 510. The first air flow channel inside the carrying ring 510 is connected to the second air flow channel in the vibration chamber 200, and the second air flow channel is connected to the high-pressure air pump 216.

[0040] When working, turn on the high-pressure air pump 216, and the high-pressure air pump 216 sends the high-pressure gas into the first air flow channel through the second air flow channel, and then sprays it out by the air flow nozzle 523. The air flow nozzle 523 enables the air flow to act on the sample accurately, and adjusts the position of the sample through the directional air flow force. If a large deviation occurs, the control device 400 is used at the same time to achieve the offset range limitation effect and avoid problems such as rollover. It should be noted that the high-pressure air pump 216 continuously sprays a stable airflow for the same sample during the entire working process. When the sample needs to be replaced, the size of the airflow can be adjusted according to the actual situation of the sample.

[0041] Reference Figure 6 In some embodiments of the present invention, the monitoring and adjusting component 520 further includes a feedback adjustment plate 521, a pressure sensor 522 and a sliding push component 524. The feedback adjustment plate 521 is slidably arranged on the airflow nozzle 523, that is, the airflow nozzle 523 penetrates the feedback adjustment plate 521. The feedback adjustment plate 521 is used to withstand the rebound airflow after the sample is applied, and the size of the rebound airflow is visualized as the displacement of the feedback adjustment plate 521; the pressure sensor 522 can be installed on the mounting ring 510 by bolts, and the pressure sensor 522 is used to detect the pressure of the feedback adjustment plate 521; the sliding push component 524 is fixed or detachably arranged on the inner wall of the mounting ring 510, and the sliding push component 524 is electrically connected to the pressure sensor 522, and is used to adjust the position of the sample.

[0042] In the above structure, when the airflow nozzle 523 sprays airflow to the sample, the airflow will exert a certain force on the sample, causing its position to change. At the same time, the airflow will rebound after hitting the sample, and this part of the rebound airflow will act on the feedback adjustment plate 521. The feedback adjustment plate 521 is subjected to the pressure of the rebound airflow and will be displaced. The magnitude of the displacement depends on the strength of the rebound airflow, and the strength of the rebound airflow depends on the actual position deviation of the sample. If the position deviation of the sample is large (that is, the closer the sample is to the airflow outlet), it will cause a larger rebound airflow, thereby causing a larger displacement of the feedback adjustment plate 521. Under the action of the larger rebound airflow, the feedback adjustment plate 521 begins to move in the direction of the pressure sensor 522 until it contacts the pressure sensor 522. Under the further action of the rebound airflow, the feedback adjustment plate 521 will squeeze the pressure sensor 522, and the pressure sensor 522 detects the pressure change of the feedback adjustment plate 521. Therefore, the output signal of the pressure sensor 522 reflects the strength of the rebound airflow, and then reflects the degree of deviation of the sample position. The greater the pressure, the stronger the rebound airflow, and the greater the displacement deviation of the sample.

[0043] Reference Figure 6In some embodiments of the present invention, the sliding push component 524 includes a controller 5241, a push telescopic rod 5242 and a return spring 5243. The controller 5241 is welded or bolted to the inner wall of the carrying ring 510; the push telescopic rod 5242 is electrically connected to the controller 5241, one end of the push telescopic rod 5242 is fixedly installed on the inner wall of the carrying ring 510, and the other end passes through the feedback adjustment plate 521; the return spring 5243 is sleeved on the push telescopic rod 5242, one end of the return spring 5243 is in contact with the carrying ring 510, and the other end is in contact with the feedback adjustment plate 521.

[0044] In the above structure, after the controller 5241 receives the signal from the pressure sensor 522, it determines the position deviation of the sample according to the pressure change, and adjusts the position of the sample by controlling the movement of the push telescopic rod 5242. When the controller 5241 issues an adjustment instruction, the push telescopic rod 5242 will move as needed, thereby pushing the sample back to the initial position. When the sample returns to the initial position, the push telescopic rod 5242 shrinks to its original state in preparation for the next adjustment. At the same time, when the sample returns to the initial position, the force of the rebound airflow on the feedback adjustment plate 521 is reduced. At this time, the return spring 5243 helps the feedback adjustment plate 521 to return to its initial state in preparation for the next adjustment. Through such a design, the sliding push component 524 can respond quickly when the position of the sample is offset, and ensure that the sample always remains in the predetermined position through precise airflow and mechanical adjustment.

[0045] Specifically, two sliding push components 524 may be correspondingly provided on each feedback adjustment plate 521, and the two sliding push components 524 are symmetrically arranged on the feedback adjustment plate 521. One end of the push telescopic rod 5242 is fixedly connected to the carrying ring 510, and the other end passes through the feedback adjustment plate 521 and is slidably connected to the feedback adjustment plate 521. A push pad is also provided at the other end of the push telescopic rod 5242, and the sample is adjusted by the push pad. In this embodiment, by providing two sliding push components 524, the feedback adjustment plate 521 can be kept balanced during the movement.

[0046] Reference Figures 4 to 7In some embodiments of the present invention, a plurality of communication function seats 511 are provided at intervals on the outer side of the carrying ring 510. Specifically, the communication function seats 511 may be three, four, five, etc., and the number thereof is not limited. When providing the communication function seats 511, the plurality of communication function seats 511 need to be arranged evenly at intervals. A connecting air cavity 514 is provided inside the connecting functional seat 511, and multiple connecting air cavities 514 are connected through a connecting duct 518; multiple functional mounting seats 512 are provided at intervals on the inner side of the mounting ring 510, and mutually connected conduction cavities 516 and gas transmission channels 517 are provided inside the functional mounting seats 512, and the gas transmission channels 517 are connected to the airflow nozzle 523, and the conduction cavity 516 is connected to the connecting air cavity 514 through the transmission channel 515; the mounting ring 510 is detachably arranged inside the vibration test chamber 219 through at least two connecting seats 513, and a connecting seat channel is provided inside the connecting seat 513, and the connecting seat channel is connected to the second airflow channel; wherein, the connecting air cavity 514, the transmission channel 515, the conduction cavity 516, the gas transmission channel 517 and the connecting seat channel constitute a first airflow channel.

[0047] It should be noted that there can be two, four, six, etc. connection seats 513, and the number is not limited and can be adjusted according to actual conditions. When there are two connection seats 513, the two connection seats 513 are respectively arranged on opposite sides of the carrying ring 510, that is, the two connection seats 513 are located at both ends of the line segment passing through the carrying ring 510. This arrangement can ensure that the carrying ring 510 is more evenly stressed under the connection of the two connection seats 513, making the connection of the carrying ring 510 more stable.

[0048] In some possible embodiments, the connection seat 513 includes a support and communication end cap 5131, which is limited on the inner wall of the vibration test chamber 219, and the inner wall of the vibration test chamber 219 is provided with a plurality of vents, and the airflow enters the support and communication end cap 5131 through the connecting pipe 218 and the vents in sequence, and the other side of the support and communication end cap 5131 is connected with the connecting plate 5132, the docking support pipe 5133 and the connecting support pipe 5134 in sequence, and finally the connecting support pipe 5134 is connected with the connecting air chamber 514. The connection seat 513 not only plays the role of connecting the carrying ring 510, but also can guide the airflow into the inside of the carrying ring 510.

[0049] Specifically, the carrying ring 510 serves as a carrier of the monitoring and adjusting device 500, and a plurality of communication function seats 511 are arranged at intervals on the outer side thereof. A communication air cavity 514 is arranged inside each communication function seat 511, and these communication air cavities 514 are interconnected through a communication conduit 518. In this way, all the communication air cavities 514 form a continuous air flow channel network, thereby providing a directional flow direction for the air flow, and further controlling the air flow to be ejected from a predetermined position.

[0050] A plurality of functional mounting seats 512 are arranged at intervals inside the mounting ring 510, and each functional mounting seat 512 is provided with a conductive cavity 516 and a gas transmission channel 517 that are interconnected. The gas transmission channel 517 is connected to the air flow nozzle 523, and the conductive cavity 516 is connected to the connecting air cavity 514 through the transmission channel 515. In this arrangement, when the high-pressure airflow enters the conductive cavity 516 from the connecting air cavity 514 through the transmission channel 515, it reaches the air flow nozzle 523 through the gas transmission channel 517 and is finally ejected.

[0051] The carrying ring 510 is installed inside the vibration test chamber 219 through the connecting seat 513. The connecting seat 513 is provided with a connecting seat channel, which is connected to the second air flow channel inside the vibration chamber 200. The second air flow channel is connected to the high-pressure air pump 216. Therefore, when the high-pressure air pump 216 is started, the high-pressure gas will pass through the second air flow channel, the connecting seat channel, the connecting air cavity 514, the transmission channel 515, the conduction cavity 516, and the gas transmission channel 517 in sequence, and finally be ejected by the air flow nozzle 523, acting on the loaded sample to adjust it back to the predetermined position.

[0052] In this embodiment, the transmission channel 515 connects the connecting air cavity 514 with the conduction cavity 516 inside the functional mounting seat 512, and the airflow can be evenly distributed to each conduction cavity 516. The conduction cavity 516 is connected to the gas delivery channel 517, and the gas delivery channel 517 is finally connected to the airflow nozzle 523. This design ensures that each airflow nozzle 523 can obtain sufficient airflow, so that the airflow force is evenly applied in all directions around the sample, so that the sample can maintain a stable position. In addition, the design of the connection seat channel enables the carrying ring 510 to be firmly installed inside the vibration test chamber 219, enhancing the overall stability of the system. The channel inside the connection seat 513 is connected to the second airflow channel, ensuring the continuity and stability of the airflow transmission.

[0053] Reference Figure 2 and Figure 4 In some embodiments of the present invention, an air flow conduction groove 211 is provided outside the vibration table 100, and an air flow conduction channel 212 is provided inside the air flow conduction groove 211. The air flow conduction channel 212 is connected to the high-pressure air pump 216 through the air flow inlet 213; a noise absorption chamber 214 is provided inside the vibration chamber 200, and a connecting pipe 218 is provided inside the noise absorption chamber 214. One end of the connecting pipe 218 is connected to the air flow conduction channel 212, and the other end is connected to the connecting seat 513; wherein the air flow conduction channel 212, the air flow inlet 213 and the connecting pipe 218 constitute a second air flow channel. In a possible embodiment, a noise reduction hole 215 is provided on the inner wall of the vibration test chamber 219.

[0054] During the vibration experiment, in order to ensure that the loaded sample can maintain a stable position, the entire system not only relies on the efficient transmission of the first airflow channel, but also requires the support of the second airflow channel to ensure the continuous supply of airflow and the stability of the system. In this embodiment, an airflow conduction groove 211 is provided on the outside of the vibration table 100, and an airflow conduction channel 212 is provided inside the airflow conduction groove 211. The airflow conduction channel 212 is connected to the high-pressure air pump 216 through the airflow inlet 213, which means that the high-pressure gas generated by the high-pressure air pump 216 can enter the airflow conduction channel 212 through the airflow inlet 213. This design ensures that the high-pressure gas can be smoothly transmitted from the high-pressure air pump 216 to the inside of the vibration chamber 200, reduces the loss of airflow during the transmission process, and ensures that the airflow ejected from the airflow nozzle has sufficient pressure and stability.

[0055] A noise absorption chamber 214 is provided inside the vibration chamber 200. The noise absorption chamber 214 enables the system to reduce noise interference while maintaining efficient airflow transmission, providing a quieter experimental environment. A connecting pipe 218 is provided inside the noise absorption chamber 214. One end of the connecting pipe 218 is connected to the airflow conduction channel 212, and the other end is connected to the connecting seat. In this way, the high-pressure gas in the airflow conduction channel 212 can smoothly enter the connecting seat 513 through the connecting pipe 218, and then enter the first airflow channel inside the mounting ring through the connecting seat channel, and finally be ejected through the airflow nozzle to act on the loaded sample, ensuring the continuity of airflow transmission.

[0056] Reference Figures 8 to 10 In some embodiments of the present invention, a vibration conduction plate 217 is provided at the bottom of the vibration test chamber 219 , and the control device 400 is provided on the vibration conduction plate 217 . The control device 400 is connected to the vibration generator 140 through the vibration conduction plate 217 .

[0057] The control device 400 includes a limit seat 410 and a sliding push assembly 420. The limit seat 410 is embedded in the center of the vibration conduction plate 217 and is used to position the sample. The sliding push assembly 420 is arranged on the limit seat 410 and is used to adjust the position of the sample. A range sink 415 is provided on one side of the limit seat 410, and a wiring serial port slot 414 is provided on the other side. A limit hole 411 is provided at the center of the bottom of the range sink 415, and the limit hole 411 is connected to the wiring serial port slot 414. A plurality of slide grooves 413 are arranged at intervals at the bottom edge area of ​​the range sink 415, and a plurality of through holes 412 are provided on the side wall of the limit hole 411, and the through holes 412 are connected to the slide grooves 413 in a one-to-one correspondence.

[0058] The sliding push assembly 420 includes a control platform 421, which is embedded in the limiting hole 411. A plurality of electric control telescopic rods 422 are arranged on the periphery of the control platform 421. The electric control telescopic rods 422 are electrically connected to the pressure sensor 522. The electric control telescopic rods 422 are slidably arranged in the slide groove 413 in a one-to-one correspondence. A clamping slider 423 is arranged at one end of the electric control telescopic rod 422 away from the control platform 421. The clamping slider 423 is slidably matched with the slide groove 413. An adjustment clamping plate 424 is arranged on the top of the clamping slider 423. The adjustment clamping plate 424 is used to adjust the position of the sample. A wiring serial port 425 is arranged at the bottom of the control platform 421. The wiring serial port 425 is limited to the wiring serial port slot 414. It should be noted that the electric control telescopic rods 422 and the push telescopic rods 5242 are arranged in a one-to-one correspondence, and the corresponding electric control telescopic rods 422 and the push telescopic rods 5242 are adjusted synchronously. The corresponding electric telescopic rod 422 and push telescopic rod 5242 are electrically connected to the same pressure sensor 522, that is, when the pressure sensor 522 receives a signal, the corresponding electric telescopic rod 422 and push telescopic rod 5242 are adjusted at the same time. Secondly, when the electric telescopic rod 422 and push telescopic rod 5242 are adjusted to the right position, they will retract to the original state to wait for the next adjustment.

[0059] During the vibration test, in order to ensure that the loaded sample can be accurately maintained at the predetermined position, a control device 400 is provided on the vibration conduction plate 217 at the bottom of the vibration test chamber 219. By connecting the vibration conduction plate 217 with the vibration generator 140, it can be ensured that the vibration can be effectively transmitted to the sample. When the vibration generator 140 is started, the vibration is transmitted to the limit seat 410 through the vibration conduction plate 217, and then transmitted to the sample. When the displacement deviation is large, the electric control telescopic rod 422 performs a telescopic action according to the instruction issued by the pressure sensor 522, and drives the adjustment clamp 424 to adjust the position of the sample by sliding the clamping slider 423 in the slide 413. The telescopic action of the electric control telescopic rod 422 is realized by the connection between the through hole 412 on the side wall of the limit hole 411 and the slide 413, ensuring that the adjustment clamp 424 can accurately adjust the position of the sample. With this arrangement, the control device 400 can adjust the bottom of the sample in real time during the vibration process, and the monitoring and adjustment component 520 adjusts the top and middle position of the sample, so as to avoid the sample from tipping over.

[0060] Reference Figure 1 In some embodiments of the present invention, the vibration chamber 200 includes an experimental chamber body 210 and a cover plate 220, and the vibration test chamber 219 is located inside the experimental chamber body 210; the cover plate 220 is limited to the top of the experimental chamber body 210 by a plurality of locking assemblies 300.

[0061] The locking assembly 300 includes a support frame 310, a cylinder 320 and a locking rod 330. The support frame 310 is arranged on the vibration table 100 and extends in the direction of the cover plate 220. The cylinder 320 is fixed to one end of the support frame 310 close to the vibration table 100. One end of the locking rod 330 is connected to the cylinder 320, and the other end is rotatably arranged at one end of the support frame 310 close to the cover plate 220. The cylinder 320 is used to drive the locking rod 330 to switch between a locking position and an unlocking position. In the locking position, the locking rod 330 limits the cover plate 220 to the vibration chamber 200; in the unlocking position, the locking rod 330 releases the limit on the cover plate 220. In some possible embodiments, four supporting base frames 130 are arranged at the bottom of the vibration table 100, and a docking seat 120 is arranged between the vibration table 100 and the supporting base frames 130.

[0062] During the vibration experiment, in order to ensure the safety and stability of the experimental chamber, the vibration chamber 200 includes an experimental chamber body 210 and a cover plate 220, and the vibration test chamber is located inside the experimental chamber body 210. In order to ensure that the cover plate 220 can be firmly fixed on the experimental chamber body 210 during the experiment, the locking assembly 300 is designed as a locking and unlocking system. When the cover plate 220 needs to be fixed on the top of the experimental chamber body 210, the cylinder 320 drives the locking rod 330 to move to the locking position.

[0063] In the locked position, the locking rod 330 limits the cover plate 220 to the vibration chamber 200, ensuring that the cover plate 220 will not loosen or shift during the vibration process. The locking rod 330 is connected to the support frame 310 through its rotating end, and can be rotated under the drive of the cylinder 320 to achieve the locking function. In the unlocked position, the locking rod 330 releases the limit on the cover plate 220, so that the cover plate 220 can be easily removed or opened from the experimental chamber body 210, so as to place or remove the sample.

[0064] Specifically, the top end of the locking rod 330 is rotatably mounted on the top end of the support frame 310, and the bottom end of the locking rod 330 is hinged to the piston of the cylinder 320. When the cover plate 220 needs to be fixed, the cylinder 320 only needs to be started, and the cylinder 320 pushes the piston to move upward, so that the locking rod 330 rotates downward around the connection with the support frame 310, so that it abuts against the cover plate 220, and then fixes the cover plate 220. When the cover plate 220 needs to be removed, the reverse operation is only required. Multiple locking assemblies 300 can be arranged in an array on both sides of the vibration bin 200.

[0065] The working principle of the present invention is provided below: When conducting the test, the spallation target sample to be tested is placed in the experimental loading barrel and then placed in the range sink 415, and then the vibration generator 140 is started to vibrate with multiple frequencies and modes, and the vibration is transmitted to the spallation target sample to be tested through the vibration conduction plate 217. During the vibration process, the high-pressure air pump 216 is started to output the airflow through the nozzle on the airflow nozzle 523, so that the airflow jet distributed in the circular array is output vertically to the experimental loading barrel. In this way, the force on the experimental loading barrel can be more uniform and large deviations can be avoided during the vibration lifting process of the experimental loading barrel. At the same time, the range sink 415 can achieve the offset range limitation effect and avoid problems such as rollover.

[0066] The present invention can, on the one hand, ensure uniform force on the sample and avoid large deviations during vibration lifting and lowering by monitoring the output of the airflow. On the other hand, through the interaction of the airflow, when the displacement deviation of the sample is large, the spacing change causes the corresponding groups of feedback adjustment plates 521 to slip due to the interaction of the airflow output, and the end closer to the sample will slide outward under the action of the airflow push pressure, thereby squeezing the pressure sensor 522, causing the pressure sensor value to change. The pressure sensor 522 passes the pressure value signal to the controller 5241 and starts the return adjustment function. The controller 5241 controls the corresponding push telescopic rod 5242 to start, and pushes the experimental loading barrel through the push pad at the end of the push telescopic rod 5242. In this process, the movement of the sliding push component 524 should be coordinated with the corresponding sliding push component 420 to start. Specifically, by adjusting the electric telescopic rods 422 by the control platform 421, the electric telescopic rods 422 are retracted, which can drive the adjustment clamps 424 to slide, so that the adjustment clamps 424 cooperate with the push pads in the sliding push components 524 to achieve push-to-position adjustment, thereby avoiding the vibration error problem caused by offset.
