Description

Technical Field

[0001] The invention belongs to the technical field of slope model loading test, and in particular relates to a slope model loading test device. Background Art

[0002] In the field of geotechnical engineering, slope stability research often uses physical model tests to simulate loads such as earthquakes and rainfall. Traditional vibration table test devices have significant limitations:

[0003] Drive mode defects: Mechanical vibration tables are directly driven by motors or hydraulics. The transmission structure has friction loss and clearance errors, resulting in low input force transmission efficiency, waveform distortion, and difficulty in achieving multi-point and multi-frequency vibration.

[0004] Inaccurate attenuation patterns: Seismic waves decay nonlinearly with distance in rock and soil, but existing devices cannot accurately simulate spatial attenuation characteristics. While electromagnetic drive solutions can avoid mechanical contact, the rate at which magnetic force decays with distance is much faster than the actual attenuation of seismic waves.

[0005] Boundary effect interference: Adjacent vibration units are difficult to move independently due to frictional resistance, resulting in uneven vibration transmission efficiency, which affects the authenticity of the internal stress field of the slope model;

[0006] Insufficient control capability: Existing magnetic drive devices are difficult to dynamically adjust the magnetic field gradient, and the electromagnetic field is easily disturbed by structural components, resulting in low driving force control accuracy.

[0007] Therefore, there is an urgent need for a slope model loading test device that can accurately simulate the spatial attenuation of seismic waves, reduce mechanical interference, and achieve multi-unit coordinated vibration. Summary of the Invention

[0008] The purpose of the embodiments of the present invention is to provide a slope model loading test device, aiming to solve the problems of attenuation law inaccuracy and boundary effect interference existing in the slope model loading test device.

[0009] The present invention is achieved by providing a slope model loading test device, comprising a simulation box, wherein a plurality of bottom plates are slidably and sealedly connected inside the simulation box, and an elastic component is provided on the simulation box for elastically supporting each bottom plate, wherein all the bottom plates are arranged side by side and slidably and sealedly connected to each other;

[0014] A further technical solution is that the output shaft of the motor C is also fixedly connected to a connecting frame, and the connecting frame is fixedly connected to a plurality of electromagnetic rings, the center lines of all the electromagnetic rings coincide with the central axis of the motor C, and all the electromagnetic rings are electrically connected to each micro-battery in the connecting frame through independent lines, and the magnetic field directions of all the electromagnetic rings are opposite to that of the electromagnetic group.

[0015] According to a further technical solution, the magnetic mechanism includes a fixed rod, a sliding seat, a magnetic block, a motor A and a fixed plate;

[0016] The bottom surface of the base plate is fixedly connected to a fixing rod, the fixing rod is fixedly connected to a fixing plate, a sliding groove is provided on the fixing plate, a sliding seat is slidably connected in the sliding groove, the sliding seat is fixedly connected to a magnetic block, the fixing plate is fixedly connected to a motor A, and the output shaft of the motor A is threadedly connected to the sliding seat.

[0017] According to a further technical solution, the magnetic barrier assembly includes a motor B, a sleeve, and a baffle made of a high-magnetic-permeability material;

[0018] The bottom plate is provided with a mounting groove, in which a motor B is provided. The output shaft of the motor B is threadedly connected to a sleeve, and the sleeve is fixedly connected to a high-magnetic-permeability material baffle. The fixing rod slides and penetrates the high-magnetic-permeability material baffle.

[0019] A further technical solution is that the boundary actuation assembly includes an electromagnet and a spring B. The side walls of the base plate are provided with open grooves, and a spring B is provided in the open grooves. The two ends of the spring B are fixedly connected to the fixed columns in the two adjacent open grooves. An electromagnet is provided at one end of the spring B, and the electromagnet is electrically connected to the micro battery on one side.

[0020] According to a further technical solution, a functional gradient material cushion is laid on the top of the base plate, wherein the functional gradient material cushion has a low elastic modulus and a high damping ratio at one end close to the magnetic drive mechanism, and a high elastic modulus and a low damping ratio at the other end away from the magnetic drive mechanism.

[0021] A further technical solution is that strip grooves are provided on the two contacting surfaces of two adjacent bottom plates, and strip oil bags are provided in the two adjacent strip grooves. Lubricating oil is stored in the strip oil bags, and a plurality of oil outlet holes are provided at the bottom of the strip oil bags.

[0022] According to a further technical solution, the elastic component includes a support plate and a spring A. The support plate is fixedly connected to the side wall of the simulation box by bolts, and multiple springs A are provided between the upper and lower end surfaces of the support plate and the inner cavity end surface of the bottom plate.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] A slope model is placed in the simulation box, and a continuously rotating magnetic drive mechanism applies periodic magnetic force to the magnetic structure. This, in turn, with the cooperation of elastic components, causes all base plates to vibrate, thereby simulating earthquakes. Adjusting the speed of the magnetic drive mechanism adjusts the rate of change of the magnetic force, and thus the vibration frequency of the base plates. Using a magnetic drive avoids the friction and gap problems associated with traditional mechanical connections, reducing energy loss and interference.

[0025] When motor C drives the electromagnetic group to rotate, the electromagnetic group continuously rotates toward the direction of the magnetic field at one end of the simulation box. The rotation centerline of the output shaft of motor C coincides with the central axis of the electromagnetic group itself, so that the magnetic field remains symmetrical during rotation. The magnetic lines of force change evenly along the circumference, causing the direction of the magnetic force acting on the magnetic mechanism to change periodically, thereby driving the magnetic mechanism to perform reciprocating vertical motion. Under the elastic force of the elastic component, the bottom plate performs vertical reciprocating motion.

[0026] When the high-permeability material baffles are close together, they can shunt the magnetic flux lines and weaken the magnetic force behind them. As each high-permeability material baffle moves away from the magnetic drive mechanism, the vertical height of each high-permeability material baffle gradually increases, and the corresponding distance becomes farther and farther. By setting each high-permeability material baffle in a vertical gradient, the magnetic force attenuation slope can be controlled.

[0027] Under the connecting action of spring B, adjacent base plates can be subjected to mutual lateral pulling force. When the two base plates move relative to each other, adjusting the magnetic force of the electromagnet can cause the magnetic attraction force of spring B to change. As the base plate moves away from the magnetic drive mechanism, increasing the magnetic attraction force of the electromagnet in the base plate can increase the lateral pulling force between the adjacent base plates, improve the transmission efficiency of the vibration force between the adjacent base plates, and compensate for the insufficient driving force caused by magnetic force attenuation.

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0038] like Figure 1-Figure 7FIG. 1 shows a slope model loading test device according to an embodiment of the present invention, comprising a simulation box 1, wherein a plurality of bottom plates 2 are slidably and sealedly connected to the inside of the simulation box 1. An elastic component 3 is provided on the simulation box 1 for elastically supporting each bottom plate 2. All the bottom plates 2 are arranged side by side and slidably and sealedly connected to each other.

[0039] The bottom of each base plate 2 is provided with a magnetic mechanism 5, which is capable of horizontal movement. A magnetic drive mechanism 8 is provided on one side of the simulation box 1. The magnetic drive mechanism 8 is horizontally arranged on the lower side of the base plate 2. The magnetic drive mechanism 8 can apply a periodic magnetic force to the magnetic mechanism 5 by continuously rotating, so that each magnetic mechanism 5 drives the corresponding base plate 2 to vibrate back and forth. A vertically movable magnetic barrier component 6 is also provided at the bottom of each base plate 2. The magnetic barrier component 6 can shunt the magnetic lines of force.

[0040] A boundary actuation assembly 4 is provided between two adjacent bottom plates 2 , and the boundary actuation assembly 4 can drive the adjacent bottom plates 2 to move relative to each other.

[0041] In this embodiment, a slope model is placed in a simulation box 1. A continuously rotating magnetic drive mechanism 8 applies a periodic magnetic force to the magnetic mechanism 5, which, in conjunction with the elastic component 3, causes all base plates 2 to vibrate, thereby simulating an earthquake. Adjusting the rotational speed of the magnetic drive mechanism 8 regulates the rate of change of the magnetic force, thereby adjusting the vibration frequency of the base plates 2. The use of magnetic drive avoids the friction and backlash issues associated with traditional mechanical connections, reducing energy loss and interference.

[0042] Theoretically, multiple independent bottom plates 2 can form a vibration input field at the bottom of the simulation box 1, which is closer to the attenuation characteristics of real seismic waves in space.

[0043] However, since the attenuation rate of magnetic force with distance is faster than the actual attenuation rate of seismic waves with distance, in this embodiment, the distance between each magnetic mechanism 5 and the magnetic drive mechanism 8 is adjusted by horizontally moving the magnetic mechanism 5, thereby regulating the size of the magnetic force between each magnetic mechanism 5 and the magnetic drive mechanism 8, and the magnetic attenuation slope is controlled by adjusting the height of the magnetic barrier assembly 6, thereby regulating the magnetic field distribution so that the attenuation of the effective driving force is close to the target seismic wave attenuation law.

[0044] like Figure 2 As shown, as a preferred embodiment of the present invention, the magnetic drive mechanism 8 includes a motor C81 and an electromagnetic group 82;

[0045] The side wall of the simulation box 1 is fixedly connected to the installation box 7, and the inner end surface of the installation box 7 is fixedly connected to the motor C81. The output shaft of the motor C81 is fixedly connected to the electromagnetic group 82. The rotation center line of the output shaft of the motor C81 coincides with the central axis of the electromagnetic group 82 itself. The electromagnetic group 82 is composed of a plurality of electromagnets that fit together. The magnetic poles of all electromagnets are set in the same direction. For example, the N poles of all electromagnets are all on the left and the S poles are all on the right. The output shaft of the motor C81 is hollow inside, and the electromagnetic group 82 is electrically connected to the battery inside the motor C81.

[0046] In this embodiment, when the motor C81 drives the electromagnetic group 82 to rotate, the electromagnetic group 82 continuously rotates toward the direction of the magnetic field at one end of the simulation box 1, and the rotation center line of the output shaft of the motor C81 coincides with the central axis of the electromagnetic group 82 itself, so that the magnetic field remains symmetrical during the rotation process, and the magnetic lines of force change evenly along the circumference, resulting in a periodic change in the direction of the magnetic force acting on the magnetic mechanism 5, thereby driving the magnetic mechanism 5 to perform reciprocating vertical motion. With the cooperation of the elastic force of the elastic component 3, the base plate 2 performs vertical reciprocating motion.

[0047] In this embodiment, the rotating electromagnetic group 82 is used as the core driving source, and the vibration frequency can be directly controlled by the rotation speed of the motor C81.

[0048] like Figure 2 As shown, as a preferred embodiment of the present invention, the output shaft of the motor C81 is also fixedly connected to a connecting frame 83, and the connecting frame 83 is fixedly connected to a plurality of electromagnetic rings 84. The center lines of all electromagnetic rings 84 coincide with the central axis of the motor C81. All electromagnetic rings 84 are electrically connected to each micro-battery in the connecting frame 83 through independent lines, and the magnetic field directions of all electromagnetic rings 84 are opposite to that of the electromagnetic group 82.

[0049] In this embodiment, multiple electromagnetic rings 84 are coaxially added outside the electromagnetic group 82. The preset reverse magnetic field of the electromagnetic rings 84 can weaken the near-field magnetic force. Adjusting the coil current on each electromagnetic ring 84 can dynamically correct the magnetic field gradient, so that the magnetic force attenuation curve is more consistent with the actual seismic wave attenuation curve.

[0050] like Figure 4 As shown in FIG. 5 , as a preferred embodiment of the present invention, the magnetic mechanism 5 includes a fixed rod 51 , a sliding seat 52 , a magnetic block 53 , a motor A 54 and a fixed plate 55 ;

[0051] The bottom surface of the base plate 2 is fixedly connected with a fixing rod 51, and the fixing rod 51 is fixedly connected with a fixing plate 55. A sliding groove is provided on the fixing plate 55, and a sliding seat 52 is slidably connected in the sliding groove. The sliding seat 52 is fixedly connected with a magnetic block 53, and the fixing plate 55 is fixedly connected with a motor A54. The output shaft of the motor A54 is threadedly connected to the sliding seat 52.

[0052] In this embodiment, the motor A54 is made of aluminum alloy. Starting the motor A54 drives the sliding seat 52 to move horizontally, and the sliding seat 52 drives the magnetic block 53 to move horizontally, thereby adjusting the distance between the magnetic block 53 and the magnetic drive mechanism 8. As the distance between the magnetic block 53 and the magnetic drive mechanism 8 changes, the magnetic force exerted on the magnetic block 53 changes, so that the magnetic force attenuation trend exerted on each base plate 2 is more consistent with the thrust attenuation trend generated by the seismic wave, thereby improving the stability of the slope model loading test results.

[0053] like Figure 5 As shown in FIG. 1 , as a preferred embodiment of the present invention, the magnetic barrier assembly 6 includes a motor B61 , a sleeve 62 and a high-permeability magnetic material barrier 63 ;

[0054] The base plate 2 is provided with a mounting groove, in which a motor B61 is provided. The output shaft of the motor B61 is threadedly connected to a sleeve 62 , and the sleeve 62 is fixedly connected to a high-magnetic-permeability material baffle 63 . The fixing rod 51 slides and passes through the high-magnetic-permeability material baffle 63 .

[0055] In this embodiment, the motor B61 is started. Under the limiting action of the fixed rod 51, the output shaft of the motor B61 pushes the sleeve 62 and the high-magnetic-permeability material baffle 63 to move vertically through threaded transmission. When the high-magnetic-permeability material baffle 63 is close to the magnetic block 53, it can divert the magnetic flux lines and weaken the magnetic force on the rear bottom plate 2; as each high-magnetic-permeability material baffle 63 moves away from the magnetic drive mechanism 8, the vertical height of each high-magnetic-permeability material baffle 63 gradually increases, so that the distance between the high-magnetic-permeability material baffle 63 and the corresponding magnetic block 53 becomes farther and farther. By setting each high-magnetic-permeability material baffle 63 in a vertical gradient, the magnetic force attenuation slope can be controlled.

[0056] On the one hand, adjusting the height of the high-magnetic-permeability material baffle 63 can change the attenuation slope of the magnetic force generated by the magnetic drive mechanism 8, so that the magnetic force attenuation law of the magnetic drive mechanism 8 is more consistent with the law of seismic wave propagation. On the other hand, the high-magnetic-permeability material baffle 63 can shield the magnetic force acting on each component in the base plate 2, thereby realizing the single magnetic force effect of the magnetic drive mechanism 8 on the magnetic block 53, and thereby realizing precise control of the thrust acting on the base plate 2.

[0057] like Figure 6 As shown, as a preferred embodiment of the present invention, the boundary actuation component 4 includes an electromagnet 41 and a spring B42, the side walls of the base plate 2 are provided with open grooves, and a spring B42 is provided in the open grooves, and the two ends of the spring B42 are fixedly connected to the fixed columns in the two adjacent open grooves, and one end of the spring B42 is provided with an electromagnet 41, and the electromagnet 41 is electrically connected to the micro battery on one side.

[0058] In this embodiment, under the connecting action of the spring B42, the adjacent base plates 2 can be subjected to mutual lateral pulling forces. When the two base plates 2 move relative to each other, adjusting the magnetic force of the electromagnet 41 can cause the spring B42 to be subjected to changes in magnetic attraction. As the base plate 2 moves away from the magnetic drive mechanism 8, increasing the magnetic attraction force of the electromagnet 41 in the base plate 2 can increase the lateral pulling force between the adjacent base plates 2, thereby improving the transmission efficiency of the vibration force between the adjacent base plates 2 and compensating for the insufficient driving force caused by the attenuation of the magnetic force.

[0059] As a preferred embodiment of the present invention, a functional gradient material cushion layer is laid on the top of the base plate 2, and the functional gradient material cushion layer has a low elastic modulus and a high damping ratio at one end close to the magnetic drive mechanism 8, and a high elastic modulus and a low damping ratio at the other end away from the magnetic drive mechanism 8.

[0060] In this embodiment, the gradient setting of the cushion layer can offset the non-uniformity of the driving force, so that the distribution of the vibration energy transmitted into the soil meets the target attenuation.

[0061] like Figure 3 As shown, as a preferred embodiment of the present invention, strip grooves 9 are provided on the two contacting surfaces of two adjacent bottom plates 2, and strip oil bags 10 are provided in the two adjacent strip grooves 9. Lubricating oil is stored in the strip oil bags 10, and a plurality of oil outlet holes are provided at the bottom of the strip oil bags 10.

[0062] In this embodiment, when adjacent base plates 2 move relative to each other, the side walls of the two strip grooves 9 on the base plate 2 will squeeze the strip oil bags 10 therein, causing the lubricating oil to flow out of the strip oil bags 10. The lubricating oil can reduce the friction between the adjacent base plates 2, allowing the base plates 2 to move independently under the push of the magnetic drive mechanism 8, thereby improving the simulation accuracy of seismic waves.

[0063] like Figure 7 As shown, as a preferred embodiment of the present invention, the elastic component 3 includes a support plate 31 and a spring A32. The support plate 31 is fixedly connected to the side wall of the simulation box 1 by bolts, and multiple springs A32 are arranged between the upper and lower end surfaces of the support plate 31 and the inner cavity end surface of the bottom plate 2.

[0064] In this embodiment, a plurality of springs A32 elastically support the bottom plate 2 , and under the magnetic force of the magnetic drive mechanism 8 , the bottom plate 2 can vibrate continuously, thereby simulating seismic waves.

[0065] In the present invention, the electromagnetic ring 84 and the high magnetic permeability material barrier 63 can reconstruct the magnetic field distribution, the functional gradient material cushion layer and the boundary actuation component 4 can regulate the vibration propagation, and through the cooperation of the elastic component 3, the boundary actuation component 4, the magnetic mechanism 5, the magnetic barrier component 6 and the magnetic drive mechanism 8, the physical limitations of magnetic attenuation can be broken through, and the simulation accuracy of the spatial attenuation of the vibration field can be significantly improved.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
