Description

Technical Field

[0001] This invention relates to the field of virtual simulation equipment technology, and specifically to a virtual simulation device for explosive impact force. Background Technology

[0002] In blasting engineering fields such as mining and building demolition, ensuring safety, precision, and professionalism during the blasting process is crucial. However, traditional on-site simulation training is hampered by high costs, the inherent dangers of explosives leading to safety risks, and environmental pollution after blasting. It struggles to simulate complex and unpredictable blasting scenarios and unexpected situations. But with breakthroughs in computer graphics, physics engines, and human-computer interaction technologies, virtual simulation technology offers a more efficient and cost-effective means of blasting training.

[0003] However, virtual simulation technology relies on the accurate establishment of digital models. These models depend on assumptions such as the complete release of explosive energy and constant environmental parameters. Different explosion effects can be obtained by increasing these assumptions. However, as the assumptions increase, the modeling difficulty, experimental parameters, and computational power requirements of the digital model also increase. Furthermore, it is difficult to determine the specific cause when the model fails.

[0004] Compared to digital model virtual simulation, simulation experiments using physical devices enhance the perception and cognition of experimenters. This allows them to simulate physical phenomena such as material deformation, stress distribution, and energy transfer under impact forces, helping them to deeply understand the characteristics and effects of impact forces. It also facilitates the calibration and optimization of simulation models, improving the accuracy and reliability of the simulation. Therefore, this invention provides a virtual simulation device for blasting impact forces, which simulates the changes in impact force applied in different directions based on the impact method. Simultaneously, it measures the impact force changes during secondary detonation in the explosion process, improving the impact force testing of complex explosion processes. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a virtual simulation device for blasting impact force, which simulates the changes in impact force applied in different directions based on the impact method, and simultaneously measures the impact force changes during secondary detonation in the explosion process, thereby improving the impact force testing of complex explosion processes.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a virtual simulation device for blasting impact force, comprising a processor for displaying and calculating a digital model, the processor being electrically connected to a measuring mechanism for physically measuring the magnitude of the impact force; the processor is used to establish impact force output models of each blasting point in the X, Y, and Z directions in the digital model respectively;

[0007] The measuring mechanism includes a detection plate corresponding to each impact force output model, and the detection plate includes a first pressure measuring plate, a second pressure measuring plate and a third pressure measuring plate;

[0008] Pressure relief tanks are fixedly connected to the bottom of the first pressure measuring plate, the second pressure measuring plate, and the third pressure measuring plate, and the pressure relief tanks are filled with buffer solution; an impact mechanism for applying impact force is provided above the first pressure measuring plate, the second pressure measuring plate, and the third pressure measuring plate.

[0009] The first pressure measuring plate, the second pressure measuring plate, and the third pressure measuring plate are used to measure the impact force data corresponding to the pressure applied by the impact mechanism. The processor inputs the impact force data into the digital model for recording and display.

[0010] Furthermore, the diameter of the pressure relief tank is larger than the diameter of the first pressure measuring plate, the second pressure measuring plate, and the third pressure measuring plate.

[0011] Furthermore, it also includes a bracket fixedly connected to the first pressure measuring plate, the second pressure measuring plate and the third pressure measuring plate, with the impact mechanism located above the bracket;

[0012] The impact mechanism includes a clamping block and a fixing rod. The clamping block is filled with a striking block. Adjacent clamping blocks are connected to the power component through the fixing rod.

[0013] The clamping block has a conical fixed cavity. The diameter of the fixed cavity at the end away from the striking block is smaller than the diameter at the end of the fixed cavity near the striking block. The clamping block has several locking blocks in a gap fit. The locking blocks are arranged in a ring around the striking block. A retaining ring is provided on the side of the locking block away from the striking block. The retaining ring is located between the locking block and the clamping block.

[0014] Furthermore, the impact mechanism also includes a combustion chamber, which is located at the position of the bracket corresponding to the detection plate. A compression block is slidably fitted inside the combustion chamber. A cavity is provided between the bottom of the compression block and the top of the combustion chamber. An injection tube is connected to the cavity, and the end of the injection tube away from the cavity passes through the combustion chamber.

[0015] The diameter of the top of the compression block is larger than the diameter of the top of the combustion chamber. The cavity is equipped with a firing pin and a friction wheel. The firing pin is fixedly connected to the center of the compression block, and the friction wheel is fixedly connected to the combustion chamber.

[0016] Furthermore, the support has a material placement chamber for replacing the test plate, and a baffle is connected to one side of the material placement chamber, which slides in conjunction with the support.

[0017] Furthermore, a lateral pressure sensor is fixedly connected to the bracket, and the lateral pressure sensor is located between the first pressure measuring plate, the second pressure measuring plate, and the third pressure measuring plate;

[0018] The lateral pressure sensor is used to acquire the oscillation force applied to the lateral pressure sensor by the first pressure measuring plate, the second pressure measuring plate and the third pressure measuring plate in real time. The processor is used to mark the oscillation force in the digital model, and then compare the consistency of adjacent oscillation forces. If they are consistent, a normal tapping command is displayed; if they are inconsistent, an abnormal tapping command is displayed.

[0019] Furthermore, a pigment layer is provided below the detection plate, and the pigment layer is arranged on the side of the pressure relief tank closest to the detection plate.

[0020] Furthermore, the pressure relief tank is equipped with several exchange pipes, which are used to transport gel layers of materials with different densities, and the colors of adjacent gel layers are inconsistent.

[0021] Furthermore, a transparent glass layer for separation is placed between adjacent gel layers.

[0022] Furthermore, it also includes a camera located on one side of the bracket. The camera is used to capture the display images inside the pressure relief tank in real time, and the processor is also used to obtain the display distance corresponding to each pressure relief tank based on the display images.

[0023] Based on the impact force data measured by the first pressure measuring plate, the second pressure measuring plate, and the third pressure measuring plate during the current time period, the display distance corresponding to the removal of the first pressure measuring plate, the second pressure measuring plate, and the third pressure measuring plate is marked according to the impact force data.

[0024] The above approach has the following beneficial effects:

[0025] 1. In this solution, during the vertical pressure application of the first pressure measuring plate, the second pressure measuring plate, and the third pressure measuring plate by the impact mechanism, the impact force generated by the impact mechanism is applied vertically, reducing the misalignment caused by gravity factors during the movement of the impact mechanism, thereby reducing the potential damage caused by misalignment force generated on the impact mechanism under gravity interference.

[0026] 2. In this scheme, during the impact of the impact mechanism on the first pressure measuring plate, the second pressure measuring plate, and the third pressure measuring plate, a huge impact force is applied to the buffer solution to form microbubbles, so that the magnitude of the impact force can be directly observed by the number of bubbles; at the same time, the impact force is dispersed by the water body to reduce the impact force on the surrounding area and improve the stability of the device.

[0027] 3. In this scheme, during the simultaneous impact of the impact mechanism on the first, second, and third pressure measuring plates, the impact force data is recorded and displayed separately through the impact force output model. The impact force data is automatically saved and processed, facilitating comparison of the deformation between the digital model and the first, second, and third pressure measuring plates under different experimental conditions. This allows for a more intuitive determination of the physical impact of the explosive impact force on the first, second, and third pressure measuring plates in different orientations, thereby improving the reliability of the simulation data.

[0028] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] The following detailed description illustrates the specific implementation method:

[0040] Example 1:

[0041] As attached Figures 1 to 6 As shown: A virtual simulation device for blasting impact force includes a processor (not shown) for displaying and calculating digital models. The processor is electrically connected to a measuring mechanism for physically measuring the magnitude of the impact force. The processor is used to establish impact force output models of each blasting point in the X, Y, and Z directions in the digital model.

[0042] The measuring mechanism includes a detection plate corresponding to each impact force output model. The detection plate includes a first pressure measuring plate 11, a second pressure measuring plate 12, and a third pressure measuring plate 13. The first pressure measuring plate 11 corresponds to the impact force output model in the X direction, the second pressure measuring plate 12 corresponds to the impact force output model in the Y direction, and the third pressure measuring plate 13 corresponds to the impact force output model in the Z direction.

[0043] A pressure relief tank 2 is fixedly connected below the first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13. The pressure relief tank 2 is filled with a buffer solution 22. The diameter of the pressure relief tank 2 is larger than the diameter of the first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13. An impact mechanism for applying impact force is provided above the first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13.

[0044] It also includes a bracket 1 fixedly connected to the first pressure measuring plate 11, the second pressure measuring plate 12 and the third pressure measuring plate 13, and the impact mechanism is located above the bracket 1; the impact mechanism includes a clamping block 3 and a fixing rod, and a striking block 31 is filled in the clamping block 3; adjacent clamping blocks 3 are connected to the power component through the fixing rod.

[0045] In this embodiment, the power component is a pendulum mechanism. The pendulum mechanism, which moves back and forth, strikes the fixed rod. The horizontal sliding grooves on both sides of the fixed rod further restrict the movement of the fixed rod and the clamping block 3, enabling the striking block 31 on the clamping block 3 to vertically impact the detection plate on the support 1 along a straight line. In another embodiment, the power component is a pneumatic actuator. The pneumatic actuator has a high-pressure gas chamber for storing compressed gas. The high-pressure gas chamber is connected to a release chamber. A piston is slidably fitted in the release chamber. The piston is fixedly connected to the clamping block 3. By releasing the compressed gas in the release chamber, the piston is quickly pushed to move the clamping block 3, so as to push the striking block 31 on the clamping block 3 to vertically impact the detection plate on the support 1 along a straight line, thereby reducing the potential damage caused by misalignment force during the contact between the striking block 31 and the detection plate.

[0046] The clamping block 3 has a conical fixed cavity 33 inside. The diameter of the fixed cavity 33 at the end away from the striking block 31 is smaller than the diameter of the fixed cavity 33 at the end near the striking block 31. Several clamping blocks 32 are fitted inside the clamping block 3 with a gap. The clamping blocks 32 are arranged in a ring around the striking block 31. A retaining ring is provided on the side of the retaining block 32 away from the striking block 31. The retaining ring is located between the retaining block 32 and the clamping block 3.

[0047] The support 1 has a material placement chamber for replacing the test plate. A baffle 14 is connected to one side of the material placement chamber, and the baffle 14 is slidably engaged with the support 1. By sliding the baffle 14 with the support 1, the material placement chamber is filled by replacing different material plates. In this embodiment, the impact force applied by the striking block 31 is detected by a pressure sensor placed between the material plates to understand the attenuation effect of different materials on the impact force. The impact force is displayed by the bubble display in the buffer solution 22 and the impact force data of the pressure sensor to determine the influence of the impact force.

[0048] The first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13 are used to measure the impact force data corresponding to the pressure applied by the impact mechanism. The processor inputs the impact force data into the digital model for recording and display.

[0049] The specific implementation process is as follows:

[0050] During the installation of the striking block 31, the striking block 31 is first placed in the center of the fixing cavity 33. The striking block 31 is then surrounded by the clamping block 32. The retaining ring is then inserted into the side of the clamping block 32 away from the striking block 31, so that the retaining ring pushes the clamping block 32 to engage and fix the striking block 31. When the striking block 31 needs to be removed later, the retaining ring in the fixing cavity 33 is pushed out in the opposite direction to loosen the retaining ring's fixing effect on the clamping block 32 and the striking block 31, so as to facilitate the disassembly and installation of the striking block 31.

[0051] Meanwhile, due to the diameter difference between the depth of the fixed cavity 33 and the surface, during the contact between the striking block 31 and the detection plate on the bracket 1, the reaction force applied by the detection plate to the striking block 31 pushes the striking block 31 to move deeper into the fixed cavity 33. As the diameter of the depth of the fixed cavity 33 decreases to improve the locking and fixing effect on the striking block 31, the stability of the striking block 31 is further improved.

[0052] The diameter difference between the first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13 and the pressure relief tank 2 facilitates the transfer of all the impact forces received by the first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13 to the surface of the buffer solution 22 inside the pressure relief tank 2, thereby facilitating the observation of changes in the bubbles within the buffer solution 22.

[0053] During the vertical pressure application process of the impact mechanism on the first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13, the impact force generated by the impact mechanism is applied vertically, reducing the misalignment caused by gravity during the movement of the impact mechanism. This reduces the potential damage caused by misalignment forces generated under gravitational interference.

[0054] When the first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13 are impacted, they impact the buffer solution 22 in the pressure relief tank 2 at high speed, exerting a huge impact force on the buffer solution 22. Taking pure water as an example, in the impact area, the water is quickly displaced by the impact force, and the local pressure drops sharply to below the saturated vapor pressure of water, causing dissolved gases or water vapor in the water to precipitate rapidly, forming tiny bubbles. The magnitude of the impact force can be directly observed by the number of bubbles. At the same time, the impact force is dispersed by the water to reduce the impact on the surrounding area and improve the stability of the device.

[0055] The processor records and displays the impact force data through the impact force output model, and automatically saves the impact force data. This facilitates comparison of the deformation between the digital model and the first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13 under different experimental conditions. This allows for a more intuitive determination of the physical impact of the explosion impact force on the first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13 in different orientations, thereby improving the reliability of the simulation data.

[0056] Example 2:

[0057] The difference from Embodiment 1 is that the impact mechanism also includes a combustion chamber 4, which is located at the position of the support 1 corresponding to the detection plate. In this embodiment, the combustion chamber 4 is welded to the support 1. In another embodiment, it is fixed to the support 1 by a clip on the support 1 so that the combustion chamber 4 can be disassembled and installed according to experimental needs. A pressure block 41 is slidably fitted inside the combustion chamber 4. A cavity is provided between the bottom of the pressure block 41 and the top of the combustion chamber 4. The cavity is connected to an injection tube, and the end of the injection tube away from the cavity passes through the combustion chamber 4.

[0058] The diameter of the top of the compression block 41 is larger than the diameter of the top of the combustion chamber 4. The cavity is provided with a firing pin 42 and a friction wheel 43. The firing pin 42 is fixedly connected to the center of the compression block 41, and the friction wheel 43 is fixedly connected to the combustion chamber 4. In this embodiment, the firing pin 42 is made of a rare earth metal alloy such as cerium-iron alloy. The firing pin 42 and the friction wheel 43 made of steel alloy generate heat through friction, so as to generate an electric spark to ignite the diesel gas in the combustion chamber 4, simulating the impact force of a secondary explosion.

[0059] The specific implementation process is as follows: The combustion chamber 4 is attached to the surface of the support 1, and diesel or gasoline is injected into the combustion chamber 4 in advance through the injection tube to form an oil-gas mixture; during the process of the striking block 31 striking the detection plate on the support 1, the pressing block 41 on the support 1 is first brought into contact, so that the pressing block 41 quickly squeezes the oil-gas mixture in the combustion chamber 4, so that the oil-gas mixture fully fills the interior of the combustion chamber 4.

[0060] When the pressure block 41 moves to its lowest point, the striking block 31 transmits impact force to the detection plate on the support 1 through the pressure block 41, which is in direct contact with the combustion chamber 4. The pressure block 41 pushes the firing pin 42 to make friction contact with the friction wheel 43, so that the firing pin 42 and the friction wheel 43 generate an electric spark to ignite the fuel gas mixture, thereby simulating the secondary contact detonation effect in existing explosives. Then, by observing the bubble generation in the buffer solution 22 in the pressure relief tank 2 and the display processing of the digital model, the impact force data monitoring under more complex conditions can be determined.

[0061] Example 3:

[0062] The difference from Embodiment 2 is that a lateral pressure sensor is fixedly connected to the bracket 1, and the lateral pressure sensor is located between the first pressure measuring plate 11, the second pressure measuring plate 12 and the third pressure measuring plate 13.

[0063] The lateral pressure sensor is used to acquire the oscillation force applied to the lateral pressure sensor by the first pressure measuring plate 11, the second pressure measuring plate 12 and the third pressure measuring plate 13 in real time. The processor is used to mark the oscillation force in the digital model and then compare the consistency of adjacent oscillation forces. If they are consistent, a normal tapping command is displayed; if they are inconsistent, an abnormal tapping command is displayed.

[0064] For example, the lateral vibration force when the impact force contacts the detection plate is detected and processed by the lateral pressure sensor to determine the magnitude of the actual vibration force. At the same time, since the striking block 31 strikes the detection plate vertically, the vibration force data should be consistent when the materials of adjacent detection plates are the same. However, if the vibration force data is inconsistent, it indicates that the impact force during the contact process between the striking block 31 and the detection plate is dispersed and inconsistent. In this case, a corresponding reminder is given to ensure the accuracy of data acquisition in subsequent experiments.

[0065] Example 4:

[0066] The difference from Embodiment 3 is that, in another embodiment, the first pressure measuring plate 11, the second pressure measuring plate 12 and the third pressure measuring plate 13 are replaced with steel plates with good impact force transmission effect, and the steel plates are used as detection plates. A pigment layer is provided under the detection plates, and the pigment layer is arranged on the side of the pressure relief tank 2 close to the detection plates.

[0067] The pressure relief tank 2 is also equipped with several exchange pipes 21, which are used to transport gel layers of materials with different densities. The colors of adjacent gel layers are different. A transparent glass layer is placed between adjacent gel layers to separate them, thereby reducing the natural sedimentation between different gel layers and improving the isolation between them.

[0068] The specific implementation process is as follows: The impact force is directly transmitted to the buffer solution 22 inside the pressure relief tank 2 through the steel plate. During the process of the impact force being compressed and diffused inside the buffer solution 22, the diffusion effect of the pigment layer is carried by the buffer solution 22, so as to make the diffusion and marking effect of the pigment layer inside the buffer solution 22 more intuitively determine the conduction and diffusion effect of different impact force magnitudes.

[0069] When the steel plate transmits the impact force to the inside of the pressure relief tank 2, the isolation effect of different materials on the explosive impact force is simulated by gel layers of different densities. This is applicable to situations such as mine blasting simulation and the development of explosive protective clothing. During the transmission of impact force, replaceable gel layers are used to simulate the segmentation effect of different materials equivalently or by substitution. The buffering change of the color diffusion effect during the change of impact force between adjacent gel layers allows for a more intuitive observation of the attenuation of the explosive impact force on continuous materials.

[0070] Example 5:

[0071] The difference from Embodiment 4 is that it also includes a camera located on one side of the bracket 1. The camera is used to capture the display image inside the pressure relief tank 2 in real time, and the processor is also used to obtain the display distance corresponding to each pressure relief tank 2 based on the display image.

[0072] Based on the impact force data measured by the first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13 during the current time period, the display distance corresponding to the removal of the first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13 is marked according to the impact force data.

[0073] For example, the impact force data measured by the first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13 are used as a basic reference. Then, the distance measured and displayed by removing the first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13 is used to determine the attenuation impact force change and diffusion of the first pressure measuring plate 11, the second pressure measuring plate 12, and the third pressure measuring plate 13.

[0074] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
