Description

Technical Field

[0001] This utility model relates to the field of shock wave technology, specifically to a counter-shear shock wave simulation device. Background Technology

[0002] Shock waves, also known as shock waves, are defined as compression waves in gaseous, liquid, and solid media where physical quantities such as stress, pressure, density, and temperature undergo abrupt changes on the wavefront. After passing through a shock wave, the pressure, density, and temperature of the gas suddenly increase, while the flow velocity suddenly decreases. The pressure jump produces an audible popping sound. The essence of a shock wave is an instantaneous release of energy. During this process, relevant parameters within the medium, such as pressure, density, and temperature, all increase in a stepwise manner. Therefore, shock waves are characterized by wide bandwidth, high resonant frequency, and short rise time. A shock wave is a necessary condition for a testing system to accurately measure shock wave overpressure. Due to the testing effect of shock waves, shear simulation damage is often performed on them. Devices utilizing the shock wave principle are also called shear shock wave simulation devices.

[0003] Shear shock wave generators mainly simulate the shear shock waves formed by multiple explosion waves in space. They are primarily used to simulate the damage of multiple explosion waves to protective facilities and personnel in space. However, traditional shear shock wave generators only detect the object on one side, which makes it impossible to obtain the destructive effect of counter-shear shock waves. Therefore, in order to ensure the effectiveness of counter-shear damage, a counter-shear shock wave simulation device is needed to ensure the quality of equipment use.

[0004] A counter-shear shock wave simulation device is proposed to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a counter-shear shock wave simulation device to solve the problem mentioned in the background art that the current conventional shear shock wave generators detect the object on one side, which makes it impossible to obtain the destructive effect of the counter-shear shock wave. Therefore, in order to ensure the effect of counter-shear destruction, a counter-shear shock wave simulation device is needed to ensure the quality of equipment use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a counter-shear shock wave simulation device, comprising an experimental chamber, a shear wave synchronization controller, and two output slot blocks;

[0007] The experimental chamber has symmetrical hinged doors on one side of the front, and observation windows are provided above one side of each of the two doors.

[0008] Also includes:

[0009] A high-voltage controller is provided on one side of the interior of each of the two output slots, and several strength membranes are fixedly installed on the other side of the interior of each of the two output slots. The interior of the test chamber is symmetrically provided with through slots on both sides. Polystyrene foam boards are provided inside the inner walls of the test chamber and the two output slots. Adjustment components are symmetrically provided on both sides of the test chamber, and clamping components are provided at the bottom of the interior of the test chamber.

[0010] The adjustment component includes a mounting plate, and fixed blocks are symmetrically mounted on the side of the mounting plate near the output slot block. A first threaded rod is rotatably connected between the fixed blocks via bearings, and one end of the first threaded rod passes through the fixed block and is fixedly mounted with a first handwheel.

[0011] The clamping assembly includes a placement plate fixedly installed inside the lower part of the experimental chamber. The placement plate has a rotating groove inside, and a drive motor is fixedly installed on one side of the rotating groove. A bidirectional lead screw is fixedly installed at the output end of the drive motor, and the end of the bidirectional lead screw away from the drive motor is rotatably connected to the placement plate through a bearing.

[0012] Preferably, the first threaded rod is fitted with a first threaded sleeve, which is fixedly connected to the output slot block. The two output slot blocks are symmetrically provided with sliding grooves on both sides, and sliding blocks are slidably connected inside the sliding grooves.

[0013] Preferably, two sets of mounting blocks are symmetrically installed on both sides of the experimental box, and a second threaded rod is rotatably connected between the mounting blocks via bearings. One end of the second threaded rod passes through the mounting block and is fixedly mounted with a second handwheel. A second threaded sleeve is fitted around the outside of the second threaded rod.

[0014] Preferably, the bidirectional lead screw is symmetrically fitted with movable blocks on its outer side, and the movable blocks are threadedly connected to the bidirectional lead screw. A clamping block is fixedly installed on the top of each of the two movable blocks, and a hard sponge block is fixedly installed on the side of each clamping block that is close to each other.

[0015] Preferably, a rotating rod is hinged to one side of the second threaded sleeve, and the end of the rotating rod away from the second threaded sleeve is hinged to the mounting plate.

[0016] Preferably, the interior of the placement plate has symmetrically provided limiting grooves above the rotating groove, and the moving block is slidably connected to the limiting grooves.

[0017] Preferably, the two sets of sliding blocks are rotatably connected to the two through slots via bearings.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this counter-shear shock wave simulation device can perform counter-shear shock wave destruction, avoiding the problem that traditional equipment cannot achieve the destructive effect of counter-shear shock waves, increasing the quality and effectiveness of the equipment, and facilitating its use on different products, thus increasing its adaptability. The specific details are as follows:

[0019] 1. Shock waves are output to the strength membranes within the output slots via a shear wave synchronous controller. The relative misalignment of the two output slots creates a punching effect on the product, ensuring the quality of the processed products. Furthermore, the polystyrene foam board absorbs the generated waves, preventing impact on the surrounding environment and people, thus increasing the safety of the equipment. Adjustment components are symmetrically arranged on both sides of the test chamber. Rotating the first handwheel drives the first threaded rod between the fixed blocks, moving the first threaded sleeve, which in turn moves the output slot. Simultaneously, the sliding block slides in the sliding groove, allowing adjustment of the shock wave position according to the product's size. Rotating the second handwheel drives the second threaded rod between the mounting blocks, moving the second threaded sleeve and causing the rotating rod to rotate. The end of the rotating rod away from the second threaded sleeve is hinged to the mounting plate, causing the mounting plate to rotate and the sliding block to rotate in the through slot, allowing adjustment of the shock wave emission angle. The adjustment components allow for adjustment of the shock wave emission tube's angle and position according to the product's size, facilitating use on different products and increasing the equipment's adaptability.

[0020] 2. A clamping assembly is installed at the bottom of the interior of the experimental chamber. When the product is placed on top of the placement plate, the drive motor is started to rotate the bidirectional lead screw in the rotating groove. The bidirectional lead screw is threadedly connected to the moving blocks, which can drive the two moving blocks to move closer at the same time, causing the clamping blocks to move. While moving, the moving blocks slide in the limiting groove to prevent them from rotating with the bidirectional lead screw. This causes the hard sponge blocks on the clamping blocks to clamp the product, thus fixing the product on the placement plate. The clamping assembly ensures that the product being simulated and tested is fixed during the use of the equipment, thereby ensuring the quality of the product simulation process.

[0028] Please see Figure 1-5This utility model provides a technical solution: a counter-shear shock wave simulation device, including an experimental chamber 1, a shear wave synchronous controller 101, and two output slot blocks 104. A chamber door 102 is symmetrically hinged to one side of the front of the experimental chamber 1, and an observation window 103 is provided above one side of each of the two chamber doors 102. The device also includes: a high-voltage controller 106 is provided on one side of the interior of each of the two output slot blocks 104, and several strength membranes 107 are fixedly installed on the other side of the interior of each of the two output slot blocks 104. Through slots 108 are symmetrically opened on both sides of the interior of the experimental chamber 1. Polystyrene foam boards 105 are provided inside the inner walls of the experimental chamber 1 and the two output slot blocks 104. Adjustment components 2 are symmetrically arranged on both sides of the experimental chamber 1, and a clamping component 3 is provided at the bottom of the interior of the experimental chamber 1. The adjustment component 2 includes a mounting plate 201, and the mounting plate 201... A fixing block 202 is symmetrically installed on one side near the output slot block 104, and a first threaded rod 203 is rotatably connected between the fixing blocks 202 via bearings. One end of the first threaded rod 203 passes through the fixing block 202 and is fixedly installed with a first handwheel 205. The clamping assembly 3 includes a placement plate 301 fixedly installed inside the lower part of the experimental chamber 1. A rotating groove 302 is opened inside the placement plate 301, and a drive motor 304 is fixedly installed on one side inside the rotating groove 302. A bidirectional lead screw 303 is fixedly installed at the output end of the drive motor 304. The end of the bidirectional lead screw 303 away from the drive motor 304 is rotatably connected to the placement plate 301 via a bearing. The angle and position of the shock wave emitting tube can be adjusted according to the position and size of the product by adjusting the assembly 2, which is convenient for use with different products and increases the adaptability of the equipment.

[0029] A first threaded sleeve 204 is fitted around the first threaded rod 203, and the first threaded sleeve 204 is fixedly connected to the output slot block 104. Sliding grooves 206 are symmetrically opened on both sides of the two output slot blocks 104, and sliding blocks 207 are slidably connected inside the sliding grooves 206, so that the movement of the first threaded sleeve 204 can drive the output slot blocks 104 to move. Two sets of mounting blocks 208 are symmetrically installed on both sides of the experimental chamber 1, and a second threaded rod 209 is rotatably connected between the mounting blocks 208 via bearings. One end of the second threaded rod 209 passes through the mounting block 208 and is fixedly mounted with a second handwheel 211. A second threaded sleeve 210 is fitted around the second threaded rod 209, which can adjust the emission angle of the shock wave. Moving blocks 305 are symmetrically fitted around the double-acting screw 303, and the moving blocks 305 are threadedly connected to the double-acting screw 303. The tops of both moving blocks 305 are fixed. The device is equipped with clamping blocks 307, and hard sponge blocks 308 are fixedly installed on the side of the two clamping blocks 307 that are close to each other. The clamping assembly 3 can ensure that the simulated test product is fixed during the use of the equipment, thus ensuring the quality of the product during the simulation process. A rotating rod 212 is hinged to one side of the second threaded sleeve 210, and the end of the rotating rod 212 away from the second threaded sleeve 210 is hinged to the mounting plate 201, so that the movement of the second threaded sleeve 210 can drive the rotating plate to rotate. The interior of the placement plate 301 is symmetrically provided with limiting grooves 306 above the rotating groove 302, and the moving block 305 is slidably connected to the limiting groove 306 to limit the moving block 305 and prevent the moving block 305 from rotating together with the bidirectional lead screw 303. The two sets of sliding blocks 207 are rotatably connected to the two through grooves 108 through bearings, so that the output groove block 104 can both move and rotate inside the through groove 108.

[0030] Working principle: Before using this counter-shear shock wave simulation device, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 5As shown, a shock wave is output between the strength membranes 107 within the output slot 104 via the shear wave synchronization controller 101. The relative misalignment of the two output slots 104 creates a punching effect on the product, ensuring the quality of the processed products. Furthermore, the polystyrene foam board 105 absorbs the generated wave, preventing impact on the surrounding environment and people, thus increasing the safety of the equipment during use. Adjustment components 2 are symmetrically arranged on both sides of the experimental chamber 1. Rotating the first handwheel 205 causes the first threaded rod 203 to rotate between the fixed blocks 202, which in turn moves the first threaded sleeve 204, thereby moving the output slot 104. Simultaneously, the output slot 104 slides... The moving block 207 slides in the sliding groove 206, thereby adjusting the position of the shock wave according to the size of the product. Rotating the second handwheel 211 drives the second threaded rod 209 to rotate between the mounting blocks 208, which in turn drives the second threaded sleeve 210 to move, thereby driving the rotating rod 212 to rotate. The end of the rotating rod 212 away from the second threaded sleeve 210 is hinged to the mounting plate 201, thereby driving the mounting plate 201 to rotate, causing the sliding block 207 to rotate in the through groove 108, thereby adjusting the emission angle of the shock wave. By adjusting the component 2, the angle and position of the shock wave emitting tube can be adjusted according to the size of the product, which is convenient for use with different products and increases the adaptability of the equipment.

[0031] A clamping assembly 3 is installed at the bottom of the interior of the experimental chamber 1. When the product is placed on top of the placement plate 301, the drive motor 304 is started to drive the bidirectional lead screw 303 to rotate in the rotating groove 302. The bidirectional lead screw 303 is threadedly connected to the moving block 305, which can drive the two moving blocks 305 to move closer at the same time, so that the clamping block 307 moves. While moving, the moving block 305 slides in the limiting groove 306 to prevent the moving block 305 from rotating with the bidirectional lead screw 303. This causes the hard sponge block 308 on the clamping block 307 to clamp the product, which can fix the product on the placement plate 301. The clamping assembly 3 can ensure that the product being simulated and tested is fixed during the use of the equipment, thus ensuring the quality of the product simulation process.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
