Description
Technical Field
[0001] The present invention relates to the field of vibration damping technology, and in particular to a tuned mass damping honeycomb platform. Background Art
[0002] The wide application of porous lightweight materials in high-energy-consuming equipment such as automobiles, high-speed trains, aerospace vehicles, and ships will not only significantly reduce the demand for conventional energy, but also reduce harmful environmental (vibration) pollution.
[0003] With the continuous expansion of the application fields of optical systems, equipment that aggregates a large amount of research results has moved out of the laboratory and into the actual application environment. High-precision laser processing equipment, measuring equipment, and vehicle, aircraft, and missile-borne laser systems in harsh vibration environments cannot avoid the impact of mechanical vibration on imaging quality, measurement accuracy, and target tracking and aiming accuracy, thus causing damage to sensitive components inside the equipment and resulting in incalculable losses. Therefore, effectively controlling the vibration shock generated during the operation of detection equipment and the interference of external vibration is one of the key factors affecting imaging quality and measurement accuracy. Summary of the Invention
[0004] In order to improve the mechanical vibration and isolate the influence of external vibration interference on the application of sensitive components in optical equipment, the present invention provides a tuned mass damping honeycomb platform.
[0005] The tuned mass damping honeycomb platform provided by the present invention adopts the following technical solutions:
[0006] A tuned mass damping honeycomb platform includes an upper plate surface. A lower plate surface is provided at the bottom of the upper plate surface. A honeycomb core layer for compressive resistance and energy absorption is provided between the upper plate surface and the lower plate surface. Adhesive layers for rapid curing connection are provided between the honeycomb core layer and the upper plate surface and the lower plate surface respectively. The upper plate surface, the lower plate surface, the honeycomb core layer, and the adhesive layers are connected to each other to form a sandwich composite structure.
[0007] Mounting ring plates for overall fixation are provided on the side surfaces of the honeycomb core layer at both the upper plate surface and the lower plate surface. A plurality of the mounting ring plates are each provided with a downward pressure structure for driving the honeycomb core layer downward. A buffer structure for buffering the downward pressure and providing stable resilience is inserted at the bottom of each of the plurality of downward pressure structures.
[0008] The honeycomb core layer is composed of a plurality of honeycomb core individuals connected to each other to form a honeycomb shape. Inertia balls for absorbing and dissipating vibration energy are provided at both the upper and lower ends inside each of the plurality of honeycomb core individuals. Extension torsion springs are provided between the two inertia balls in each of the plurality of honeycomb core individuals to provide connection and resilience.
[0009] By adopting the above technical solution, multiple honeycomb core individuals are fixed to form a honeycomb core layer. At the same time, the formed honeycomb core layer is interconnected by the upper plate surface, the lower plate surface and the adhesive layer to form a sandwich composite structure, which improves the overall stability and increases the upper limit of vibration resistance. When the platform as a whole is subjected to vibration from the detection equipment, the inertia balls in the multiple honeycomb core individuals generate a reverse force to offset it. When the platform is subjected to external vibration force, the vibration force is transmitted to the buffer structure to be isolated, and cooperates with the downward pressure structure to withstand the slow and stable downward pressure of the external and detection equipment at the same time, and releases the vibration force, thereby improving the vibration generated during the operation of the detection equipment and isolating the vibration interference generated by the outside world, effectively improving the imaging quality and measurement accuracy.
[0010] Preferably, damping grooves are provided inwardly at both the upper and lower ends of the honeycomb core individual, and two limiting grooves are provided at the two end surfaces of the honeycomb core individual. Limiting rings are inserted in the two limiting grooves, and a plurality of connecting torsion springs fixed to the inertia ball are fixed on the opposite side of the two limiting rings.
[0011] By adopting the above technical solution, the opening of the damping groove provides space for the inertia ball to move, thereby ensuring that the inertia ball can generate sufficient reverse force. At the same time, the opening of the limit groove limits the installation of the limit ring to prevent deviation, and connects the torsion spring to the inertia ball, thereby driving the inertia ball to generate push and pull force, thereby promoting the generation of reverse force.
[0012] Preferably, the honeycomb core individuals are connected to the bottoms of the two damping grooves and are provided with a central through hole, and the stretch torsion spring is movably connected to the central through hole.
[0013] By adopting the above technical solution, the opening of the middle through hole provides a movable space for the connection of the extension torsion spring, so that the extension torsion spring is connected to the two inertia balls at the same time, thereby increasing the reverse force generated by the inertia balls and improving the vibration reduction effect.
[0014] Preferably, sealing sleeves are fixedly mounted on both upper and lower ends of the honeycomb core, the side surfaces of the two sealing sleeves abut against the inner wall of the damping groove, and the bottoms of the two sealing sleeves abut against the top of the limiting ring.
[0015] By adopting the above technical solution, the sealing sleeve seals the damping groove to prevent external debris from entering the honeycomb core and causing damage, and at the same time applies downward pressure to the limiting ring to fix the limiting ring in the damping groove.
[0016] Preferably, the pressing-down structure includes four-corner fixing plates fixed between every two of the plurality of mounting ring plates. Abutting blocks protrude between every two adjacent mounting ring plates on the plurality of four-corner fixing plates. A plurality of pressing-down cones protrude from the bottom of the plurality of four-corner fixing plates. Trapezoidal grooves are arranged between the plurality of pressing-down cones. Two expansion plates are rotatably arranged at the bottom of the one in the center of the plurality of pressing-down cones. Compression torsion springs are connected between the two expansion plates.
[0017] By adopting the above technical solution, the abutting blocks abut against the two mounting ring plates, thereby forming a mutual acting force to improve stability. The movement of the four-corner fixing plates drives the pressing-down cones to press down, thereby releasing the vibration force received by the whole platform. The expansion plates move downward synchronously to contact the semi-solid material for expansion, increasing the contact area and improving the transmission of pressure. The compression torsion spring provides a resilience force at the expansion opening of the expansion plates, thereby ensuring that the expansion plates return to the normal position.
[0018] Preferably, a limiting hole for penetration is opened on one side of the top of the four-corner fixing plate, and the limiting hole penetrates through the bottom of the four-corner fixing plate to form a connection.
[0019] By adopting the above technical solution, the opening of the limiting hole limits the lifting movement of the four-corner fixing plate, so that the four-corner fixing plate can only move longitudinally along the buffer block, preventing additional offset and improving stability.
[0020] Preferably, the buffer structure includes buffer blocks arranged at the bottom of the four-corner fixing plates and inserted movably. Pressing-down grooves are opened at the tops of the buffer blocks. Bottom grooves are opened at one side of every two adjacent mounting ring plates at the bottoms of the pressing-down grooves. Boosting ports communicating with the pressing-down grooves are opened through the side walls on both sides of the bottom grooves.
[0021] By adopting the above technical solution, the pressing-down grooves are opened on the surfaces of the buffer blocks, thereby reserving space for the pressing-down of the four-corner fixing plates. At the same time, semi-solid materials for isolating and buffering vibration are stored in the pressing-down grooves, thereby improving the vibration damping effect. The boosting ports compress the moving path of the semi-solid materials, thereby generating a pushing force to provide power for reversely pushing the four-corner fixing plates subsequently.
[0022] Preferably, telescopic covers are sleeved and connected to the surfaces of the two boosting ports. Reaction blocks are fixed to the tops of the telescopic covers. Docking cavities communicating with the boosting ports are opened inside the reaction blocks. Side grooves communicating with the docking cavities are opened on both sides of the outer surfaces of the reaction blocks. Inflatable sacs are fixed to the surfaces of the two side grooves.
[0023] By adopting the above technical solution, the telescopic covers connect the reaction blocks with the pressing-down grooves, so that the semi-solid materials in the boosting ports enter the docking cavities. While ensuring the rising of the reaction blocks, the inflatable sacs are inflated, and then a thrust is provided for the four-corner fixing plates.
[0024] Preferably, a limiting rod is fixedly arranged at a position on the bottom of the pressing groove between the two bottom grooves. The top of the limiting rod is movably inserted through the limiting hole. A perfusion hole is formed through the top of the limiting rod, and the bottom of the perfusion hole penetrates through the side surface of the limiting rod to communicate with the pressing groove.
[0025] By adopting the above technical solution, the limiting rod is inserted out of the limiting hole, so as to keep the longitudinal movement of the buffer block and the four-corner fixing plate, and avoid loosening during connection.
[0026] Preferably, a sealing plug is inserted at the position of the perfusion hole at the top of the limiting rod, and the side surface of the bottom of the sealing plug is in pressing contact with the inner wall of the perfusion hole to form a seal.
[0027] By adopting the above technical solution, the sealing plug seals the perfusion hole. Pull out the sealing plug, and the semi-solidified material in the pressing groove can be supplemented through the perfusion hole, and at the same time, the air pressure in the pressing groove is released.
[0028] In summary, the present invention includes at least one of the following beneficial technical effects:
[0029] 1. The vibration generated by the detection device is transmitted to the honeycomb core layer, so that each honeycomb core receives the vibration. Thus, the connecting torsion spring exerts a pushing and pulling force on the inertial ball, and the inertial ball receives the pushing and pulling force and shakes in the direction opposite to the vibration frequency, so as to reduce the vibration. At the same time, as the four-corner fixing plate is pressed into the buffer block, the vibration force is released during the movement process, effectively improving the overall shaking caused by the vibration generated by the detection device and avoiding damage to sensitive components.
[0030] 2. With the help of external vibration transmitted to the buffer block, the four-corner fixing plate is driven to press down, thereby squeezing the semi-solidified material in the pressing groove, so that the recoil block pushes up the four-corner fixing plate to offset the downward pressure, and at the same time releases the vibration force. At the same time, during the transmission process of the vibration force, it is blocked by the semi-solidified material, and the vibration force is locked in the buffer structure part as a whole, avoiding problems with image quality and measurement accuracy caused by vibration to the platform part.

[0045] The following further elaborates on the present invention in conjunction with the attached Figures 1 - 8 for a more detailed description of the present invention.
[0046] The embodiment of the present invention discloses a tuned mass damping honeycomb platform.
[0047] Refer to Figure 1 、 Figure 2 、 Figure 3A tuned mass damping honeycomb platform comprises an upper plate surface 1, the lower end surface of the upper plate surface 1 being connected to a lower plate surface 8, and the surfaces of the upper plate surface 1 and the lower plate surface 8 facing each other are coated with an adhesive layer 2, and the adhesive layer 2 uses KJ-6363F09 fast-curing AB adhesive, which has the function of absorbing stress while maintaining a good bonding effect, thereby reducing the risk of cracking caused by thermal expansion and contraction or vibration of the material, and the two adhesive layers 2 are bonded and fixed to the surfaces of the opposite sides thereof, and the honeycomb core layer 3 is composed of a plurality of honeycomb core individuals 31 fixedly connected, and each honeycomb core individual 31 is configured as a hexagonal block with a thickness of 0.25 mm and an area of 3.2 cm², and the upper plate surface 1, the lower plate surface 8, the honeycomb core layer 3 and the adhesive layer 2 are superimposed and connected to each other, thereby forming a three-layer sandwich structure with good cushioning and shock absorption effect;
[0048] The four side surfaces of the honeycomb core layer 3 are fixed with mounting ring plates 4, and the four adjacent mounting ring plates 4 are screwed with downward pressing structures 5. The downward pressing structure 5 is L-shaped as a whole to connect two adjacent mounting ring plates 4, thereby forming the overall stability of the four mounting ring plates 4.
[0049] It should be noted that the upper plate surface 1 and the honeycomb core individual 31 are both set to 430 series high magnetic permeability nickel alloy stainless steel material with a small thermal deformation coefficient, and the lower plate surface 8 is set to a steel plate material with high rigidity and vibration isolation effect. At the same time, multiple M6 threaded holes with an aperture of 25mm*25mm can be opened on the surface of the upper plate surface 1 to facilitate the installation of various types of translation stages and adjustment frames.
[0050] Reference Figure 3 、 Figure 4 , multiple honeycomb core individuals 31 have damping grooves 32 opened inward at both upper and lower ends, and a through hole 38 is opened in the center of the two damping grooves 32 in the honeycomb core individual 31 to connect the two damping grooves 32. The two end surfaces of the multiple honeycomb core individuals 31 are located on one side of the damping groove 32 and have limiting grooves 33 opened inward. The limiting grooves 33 are T-shaped and distributed around the damping groove 32. A limiting ring 35 is longitudinally inserted in the limiting groove 33. The outer surface of the limiting ring 35 is protruding with a T-shaped block that is engaged with the limiting groove 33, so that the limiting ring 35 can move up and down along the limiting groove 33.
[0051] On the opposite side surfaces of the two limiting rings 35, a plurality of connecting torsion springs 37 are fixedly arranged around. At the ends of the plurality of connecting torsion springs 37 far from the limiting rings 35, inertia balls 36 are fixedly connected. On the opposite sides of the two inertia balls 36, extension torsion springs 39 are fixedly arranged. The extension torsion springs 39 are movably inserted through the middle through holes 38 to maintain the connection of the two inertia balls 36 and provide a resilient pulling force. The plurality of connecting torsion springs 37 and the extension torsion springs 39 are all set in an extended state. The calculation formula of the torsion spring force is F = kx, where F represents the torsion spring force, k represents the torsion spring constant (the elastic force generated by the torsion spring under force per unit length), and x represents the torsion spring compression amount (the displacement distance of the torsion spring from the original state to the compressed state). And the connecting torsion springs 37 and the extension torsion springs 39 can calculate the elastic force through this formula.
[0052] It should be noted that sealing sleeves 34 are adhesively arranged on the surfaces at both ends of the plurality of honeycomb core individuals 31. The sealing sleeves 34 entirely cover the surfaces of the honeycomb core individuals 31 to seal the damping grooves 32. At the same time, the bottom of the sealing sleeves 34 protrudes into the damping grooves 32, and T-shaped protrusions are arranged at the positions where the protruding parts are located in the limiting grooves 33. When the sealing sleeves 34 are pressed into the damping grooves 32, the T-shaped blocks of the limiting rings 35 are extruded to keep the limiting rings 35 fixed.
[0053] Refer to Figure 2 、 Figure 5 、 Figure 7 As shown in
[0054] The pressing structure 5 includes a four-corner fixing plate 51 fixedly arranged between two adjacent mounting ring plates 4. On one side of the four-corner fixing plate 51 at the included angle of the two mounting ring plates 4, a butting block 52 protrudes. The two side surfaces of the butting block 52 are in contact with the mounting ring plates 4. Cooperating with the four four-corner fixing plates 51, they are all threadedly connected to the mounting ring plates 4 through screws to improve the stability effect. At the positions of the two mounting ring plates 4 on the lower end surface of the four-corner fixing plate 51, a plurality of pressing cones 53 protrude. The pressing cones 53 are composed of cones with three trapezoidal surfaces, and trapezoidal grooves 54 in the shape of trapezoids are arranged between each pair of cones, so as to facilitate increasing the thrust received by the four-corner fixing plate 51.
[0055] Refer to Figure 6 、 Figure 7 、 Figure 8, the buffer structure 6 includes buffer blocks 61 inserted and arranged at the bottom of the four-corner fixing plates 51. The width of the buffer blocks 61 is greater than that of the four-corner fixing plates 51, and a downward pressure groove 62 with the same width and shape as the four-corner fixing plates 51 is inwardly formed on the upper end surface of the buffer blocks 61. Taking the insertion of the four-corner fixing plates 51 into the downward pressure groove 62 as the alignment point, a bottom groove 65 is formed at the position of the middle cone of the downward pressure cone 53. The bottom groove 65 is aligned and inserted with the middle cone of the downward pressure cone 53. The bottom of the bottom groove 65 extends in a T shape to both sides, and a pressure boosting port 66 is formed through the downward pressure groove 62 at the extending end. And telescopic covers 68 are fixedly arranged at the positions of the two pressure boosting ports 66 at the bottom of the downward pressure groove 62. The telescopic covers 68 can be extended under the action of thrust;
[0056] The other end of the telescopic cover 68 away from the pressure boosting port 66 is fixedly provided with a recoil block 67. The two recoil blocks 67 are integrally trapezoidal and are fitted with the shape of the trapezoidal groove 54. Side grooves 610 are inwardly formed on both side surfaces of the recoil block 67 facing the trapezoidal groove 54. Inflatable capsules 611 are hermetically connected in the two side grooves 610. The inflatable capsules 611 are made of rubber material and can be inflated and bulged under the action of thrust. At the same time, a docking cavity 69 is formed at the position where the lower end surface of the recoil block 67 is aligned with the pressure boosting port 66. The top of the docking cavity 69 penetrates through the recoil block 67 and is respectively communicated with the two side grooves 610.
[0057] It should be noted that a limiting rod 63 is protrudingly arranged at the position of the limiting hole 57 on the bottom surface of the downward pressure groove 62. The shape of the limiting rod 63 is fitted with the limiting hole 57, so that the limiting rod 63 is longitudinally inserted into the limiting hole 57. At the same time, a perfusion hole 64 is formed in the middle of the limiting rod 63. The perfusion hole 64 is docked with an external input device for inputting semi-solidified material into the downward pressure groove 62. The perfusion hole 64 communicates the top and bottom of the limiting rod 63, so that the downward pressure groove 62 can be communicated with the outside through the perfusion hole 64. A sealing plug 7 is plugged at the top of the perfusion hole 64 to keep the perfusion hole 64 sealed.
[0058] The implementation principle of a tuned mass damping honeycomb platform in an embodiment of the present invention is as follows: When using this device, a person fixes the device to be detected on the surface of the upper plate surface 1. The device is placed on the surface of the upper plate surface 1 and applies pressure to the platform by its own weight. The pressure is transmitted from the mounting ring plate 4 to the four-corner fixing plates 51, so that the four-corner fixing plates 51 are integrally pressed downward along the groove of the downward pressure groove ⑥. At this time, the downward pressure groove 62 is filled with semi-solidified material. As the four-corner fixing plates 51 are pressed in, mutual forces are generated by squeezing the semi-solidified material, so that the expansion plates 55 are unfolded to both sides, thereby increasing the contact area with the semi-solidified material. During the contact process, the semi-solidified material provides initial buffering to the four-corner fixing plates 51 by the expansion plates 55;
[0059] Subsequently, as the expansion plate 55 continues to press downwards, part of the semi-solid material is pressed into the docking cavity 69 through the pressure boosting port 66, thereby lifting the recoil block 67. The recoil block 67 is lifted upwards and contacts the trapezoidal groove 54. In cooperation with the semi-solid material, the expansion bladder 611 is filled through the side groove 610. The two sides of the recoil block 67 contact the trapezoidal groove 54 again, generating a secondary buffer for the four-corner fixing plate 51.
[0060] When the semi-solid material fully receives the weight impact of the detection device, the semi-solid material slowly flows back into the bottom groove 65 through the pressure boosting port 66, thereby causing the recoil block 67 to slowly descend until the supporting force provided by the semi-solid material balances the weight of the detection device.
[0061] Subsequently, the detection device performs the detection work. As the detection device generates vibrations during operation, the vibrations are first transmitted from the upper plate surface 1 to the honeycomb core layer 3, and are shared by multiple honeycomb core individuals 31, thereby greatly reducing the vibrations. When the honeycomb core individuals 31 receive vibrations and are about to generate synchronous vibrations, the inertial balls 36 are affected by the vibrations and thus perform synchronous vibrations. As the inertial balls 36 vibrate, push-pull forces are applied to multiple connecting torsion springs 37. Subsequently, after the vibrations of the current frequency end, the connecting torsion springs 37 rebound and apply reverse push-pull forces to the inertial balls 36, so that when the next frequency vibration is transmitted, it abuts against the reverse push-pull forces, thereby forming an effect of reducing vibrations for the second time;
[0062] At this time, the entire platform is in a state of being pressed against the surface of the semi-solid material. While the vibration force generated from the outside is isolated and weakened by the semi-solid material, with each vibration generated, the expansion plate 55 applies a downward pressure equal to the vibration force to the semi-solid material, thereby causing the recoil block 67 and the expansion bladder 611 to apply synchronous rebound forces to the trapezoidal groove 54. The four-corner fixing plate 51 maintains the stability of the platform, thereby providing a good and precise detection environment for the detection device.
[0063] The above are only optional embodiments of the present disclosure and are not used to limit the present disclosure. For those skilled in the art, various changes and modifications can be made to the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.
