Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel structure vibration reduction, in particular to a steel enclosure structure induction vibration reduction device. BACKGROUND

[0002] Steel structure workshop is a kind of building type which takes steel as the main structural material and adopts steel frame, steel beam, steel column and other components to form the structure, and is widely used in industrial production, warehousing, logistics, commerce and other fields.

[0003] As the main structure form of heavy and large-span industrial building, steel structure workshop often bears frequent vibration load, in order to meet the requirements of industrial production process, the open bay and span of such steel structure are large, so a large number of column bracing steel components such as roof support and column support are needed.

[0004] In the structural design, compared with the main load-bearing components such as beams and columns, the load borne by these column bracing steel components is small, and the calculation from the strength angle is often in surplus; but because the support distance is large, such components are mostly slender rods with small stiffness, and the deformation under the action of vibration load is much larger than that of the main components, so the support structure which meets the strength requirements often cannot meet the use requirements of stiffness, therefore, the sectional size of these column bracing steel components is often increased or the support is densified to reduce the deformation during the design, but both of these two ways will greatly increase the material consumption, so that the material strength of the steel structure cannot be fully utilized, causing the waste of materials, and also leading to the problem of increasing the self weight of the steel structure. SUMMARY

[0005] The purpose of the present application is to provide a steel enclosure structure induction vibration reduction device which can construct a non-uniform magnetic field between two adjacent columns, and generate instantaneous current when the column bracing steel component vibrates in the non-uniform magnetic field, so as to convert the harmful mechanical energy of vibration into heat loss through electromagnetic induction, thereby realizing the vibration reduction effect of the column bracing steel component.

[0006] In order to achieve the above purpose, the present application provides a steel enclosure structure induction vibration reduction device, which comprises a column, a column bracing steel component located between two adjacent columns, and a magnetic material fixedly connected with the column.

[0007] The magnetic materials on the two adjacent columns are one-to-one corresponding, and the magnetic pole directions of the one-to-one corresponding magnetic materials are opposite.

[0008] The two one-to-one corresponding magnetic materials are arranged in a staggered manner along the cross-sectional direction of the column.

[0009] Preferably, the magnetic material is eccentrically arranged, and only one end of the magnetic material extends beyond the boundary of the column;

[0010] Corresponding to each other, the two magnetic materials extend towards the inside and outside of the column respectively.

[0011] Preferably, the column is provided with a plurality of magnetic materials corresponding to the magnetic materials of the adjacent column.

[0012] Preferably, the column is provided in a plurality.

[0013] Preferably, corresponding magnetic materials on two adjacent columns are arranged as a group of magnetic materials.

[0014] There are at least two groups of magnetic materials on the same column.

[0015] Preferably, on the same column, the magnetic pole directions of any two magnetic materials in the same group of magnetic materials are the same.

[0016] Preferably, on the same column, the magnetic materials belonging to different groups of magnetic materials are distributed in a circumferential direction of the column.

[0017] Preferably, along the height direction of the column, the magnetic materials are distributed in a spiral manner.

[0018] Preferably, on the same column, the magnetic properties of two adjacent magnetic materials in the height direction repel each other.

[0019] According to the above technical solution, the application utilizes the principle that when a metal conductor moves irregularly in a non-uniform magnetic field, a transient induced current is generated due to electromagnetic induction, and then the conductor is subjected to the action of Ampere force, which will hinder the movement of the conductor. By constructing a non-uniform magnetic field between two adjacent columns, the vibration damping effect of the column support steel member between the two columns can be achieved.

[0020] When the column support steel member is in a uniform magnetic field environment and vibrates, the magnetic flux in the several planes enclosed by the column support steel member will change, so that a transient induced current will be generated in the vibrating column support steel member, thereby causing the column support steel member to be subjected to the action of Ampere force. According to Lenz's law, the effect of Ampere force will hinder the movement of the conductor in the magnetic field. Since in a non-uniform magnetic field environment, the Ampere forces acting on different parts of the column support steel member cannot be mutually cancelled out, but the overall effect of the Ampere forces acting on the column support steel member is to make it vibrate rapidly and attenuate. From the energy point of view, the harmful mechanical energy of the column support steel member itself is utilized, and through electromagnetic induction, these mechanical energies are converted into electric energy and then into heat dissipated in the environment.

[0021] Since the column support steel member itself is a good conductor and has good grounding protection, no electric charge is accumulated. Thus, the method for constructing the non-uniform magnetic field environment can realize the suppression of the vibration of the column support steel member 3, and the whole process has no additional energy consumption, which is safe, economical, green and environmentally friendly.

[0022] The steel enclosure induction vibration damping device needs to design the distribution state of the magnetic material based on the distribution of the steel structure on site, and the non-uniform magnetic field between the two columns 2 is formed by reasonably setting the position of the magnetic material. When the column support steel member vibrates, the magnetic flux in the several planes enclosed by the column support steel member changes, and then the instantaneous current is generated, and the ampere force that prevents the vibration is formed.

[0023] The magnetic materials on the adjacent two columns are arranged one-to-one, and the opposite two faces of the one-to-one two magnetic materials are respectively set as N pole and S pole, that is, the magnetic pole directions of the one-to-one two magnetic materials are opposite. The magnetic induction lines are generated between the one-to-one two magnetic materials, and the direction of the magnetic induction lines is from the N pole to the S pole, and the magnetic induction lines pass through the area between the two columns. Preferably, the heights of the one-to-one two magnetic materials are consistent, and then the magnetic induction lines are distributed along the horizontal direction.

[0024] By arranging the two one-to-one magnetic materials in a staggered manner, a non-uniform magnetic field in which the magnetic induction lines are not parallel to the plane of the column support steel member can be formed between the two columns. The vibration of the column support steel member can be regarded as a translation or rotation around the axis along the normal direction of the plane of the column support steel member. When the column support steel member generates displacement in the non-uniform magnetic field between the two columns, the magnetic flux of the several closed planes enclosed by the column support steel member will change. Since the closed planes of these good conductors are all composed of good conductors, these closed planes will spontaneously form a loop with the surrounding steel structure. Thus, the column support steel member will be subjected to multiple ampere forces that prevent its vibration during the vibration process. According to the Lenz law, the effect of these ampere forces will hinder the change of the magnetic flux of the several closed planes enclosed by the column support steel member, and then hinder the vibration of the column support steel member. In addition, along the length direction of the column support steel member, the sizes and directions of these ampere forces at different positions of the column support steel member are not completely the same, but the total effect of the performance is to hinder the relative motion. Therefore, under the joint action of these ampere forces, the vibration of the column support steel member will rapidly attenuate until it returns to the equilibrium state.

[0036] The specific embodiments of the application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the application, and are not intended to limit the application.

[0037] In the present application, unless otherwise specified, the orientation words included in the terms such as "adjacent, opposite, staggered, circumferential, vertical, between" only represent the orientation of the term in the conventional use state or the common name understood by those skilled in the art, and should not be considered as a limitation of the term.

[0038] A steel enclosure induction vibration reduction device includes a column 2, an inter-column support steel member 3 between two adjacent columns 2, and a magnetic material 1 fixedly connected to the column 2.

[0039] The magnetic material 1 on the two adjacent columns 2 is arranged one-to-one, and the magnetic pole direction of the one-to-one magnetic material 1 is opposite.

[0040] The two one-to-one magnetic materials 1 are arranged in a staggered manner along the cross-sectional direction of the column 2.

[0041] Through the implementation of the above technical solution, by using the principle that when a metal conductor moves irregularly in a non-uniform magnetic field, a transient induced current is generated due to electromagnetic induction, and then the conductor is affected by the Ampere force, which will hinder the movement of the conductor, by constructing a non-uniform magnetic field between the two adjacent columns 2, the vibration damping effect of the column support steel member 3 between the two columns 2 can be achieved.

[0042] When the column support steel member 3 is in a uniform magnetic field environment and vibrates, the magnetic flux in the several planes enclosed by the column support steel member 3 will change, so that a transient induced current will be generated in the vibrating column support steel member 3, thereby causing the column support steel member 3 to be affected by the Ampere force. According to Lenz's law, the effect of the Ampere force will hinder the movement of the conductor in the magnetic field. Since in a non-uniform magnetic field environment, the Ampere forces at different positions of the column support steel member 3 cannot be balanced, but the overall effect of the Ampere forces on the column support steel member 3 is to make its vibration decay rapidly. From the perspective of energy, the harmful mechanical energy of the vibration of the column support steel member 3 is converted into electrical energy through electromagnetic induction, and then the electrical energy is converted into heat and dissipated in the environment.

[0043] Since the column support steel member 3 itself is a good conductor and has good grounding protection, it will not accumulate electric charge. Therefore, this method of constructing a non-uniform magnetic field environment can achieve the suppression of the vibration of the column support steel member 3, and the entire process does not have any additional energy consumption, which is safe, economical, green and environmentally friendly.

[0044] The steel enclosure structure induction vibration damping device needs to design the distribution state of the magnetic material 1 based on the distribution of the steel structure on site. By reasonably setting the position of the magnetic material 1, the column support steel member 3 is located in a non-uniform magnetic field between two columns 2, so that when the column support steel member 3 vibrates, the magnetic flux in the several planes enclosed by the column support steel member 3 changes, thereby generating a transient current and forming an Ampere force that prevents the vibration of the column support steel member 3.

[0045] The magnetic material 1 on the two adjacent columns 2 is arranged one-to-one, and the magnetic pole direction of the one-to-one magnetic material 1 is opposite.

[0046] By arranging two one-to-one corresponding magnetic materials 1 in a staggered manner, a non-uniform magnetic field can be formed between the two columns 2, in which the magnetic lines of force are not parallel to the plane in which the column support steel member 3 is located. The vibration of the column support steel member 3 can be considered as a translation or rotation around the normal direction of the plane in which the column support steel member 3 is located. When the column support steel member 3 is displaced in the non-uniform magnetic field between the two columns 2, the magnetic flux of the closed plane enclosed by the column support steel member 3 will change. Since the closed plane of these good conductors is composed of good conductors, these closed surfaces will spontaneously form a loop with the surrounding steel structure. Therefore, the column support steel member 3 will be subjected to multiple Ampere forces that prevent it from vibrating during the vibration process. According to Lenz's law, the effect of these Ampere forces will hinder the change of the magnetic flux of the closed plane enclosed by the column support steel member 3, thereby hindering the vibration of the column support steel member 3. In addition, along the length direction of the column support steel member 3, the size and direction of these Ampere forces at different positions of the column support steel member 3 are not completely the same, but the overall effect is to hinder relative motion. Therefore, under the joint action of these Ampere forces, the vibration of the column support steel member 3 will rapidly attenuate until it returns to an equilibrium state.

[0047] In this embodiment, preferably, the magnetic material 1 is eccentrically arranged, and the magnetic material 1 has and only one end extending beyond the boundary of the column 2.

[0048] The two one-to-one corresponding magnetic materials 1 respectively extend inward and outward of the column 2.

[0049] Since the magnetic poles of the two magnetic materials 1 are opposite, i.e., the two opposite surfaces of the two magnetic materials 1 are respectively set as N-pole and S-pole, by eccentrically arranging the magnetic material 1, a non-uniform magnetic field can be effectively constructed. When the two one-to-one corresponding magnetic materials 1 respectively extend inward and outward of the column 2, as shown in Figure 4 the magnetic lines of force between the two magnetic materials 1 will not be parallel to the column support steel member 3, so that the magnetic induction intensity (magnetic flux density) at different positions will be different. At the same time, when the rod vibrates, the movement speed of the middle part of the rod will be greater than that of the end part due to the constraint of the edge, so that a potential difference will be generated at different positions, and then an induced current and an Ampere force will be generated. According to Lenz's law, the overall effect of the Ampere force in the column support steel member 3 will hinder the vibration of the column support steel member 3.

[0050] By setting the magnetic material 1 to extend beyond the boundary of the column 2, not only can a non-uniform magnetic field be constructed between two adjacent columns 2, but the range of the non-uniform magnetic field can also be expanded, so that the non-uniform magnetic field can cover the area outside the boundary of the column 2. When the inter-column bracing steel member 3 vibrates to a position beyond the boundary of the column 2, it can still be affected by the Ampere force, and the force is sufficient to quickly restore the inter-column bracing steel member 3 that has vibrated out of the boundary of the steel structure to the equilibrium position.

[0051] In this embodiment, preferably, the column 2 is provided with a plurality of magnetic materials 1 corresponding to the magnetic materials 1 of the adjacent column 2.

[0052] As shown in Figure 1 , the magnetic poles of the magnetic materials 1 corresponding to the adjacent two columns 2 are opposite and have the same height, so as to generate a horizontal magnetic field between the two columns 2. The same column 2 is provided with a plurality of magnetic materials 1 corresponding to the magnetic materials 1 of the adjacent column 2, which are located at different height positions respectively, so that a magnetic field can exist along the height direction of the column 2, and the inter-column bracing steel member 3 can be affected by the non-uniform magnetic field at all positions along the length direction during vibration.

[0053] Preferably, the magnetic materials 1 are arranged periodically and spaced apart along the height direction of the column 2, so that the magnetic field between the two columns 2 is stronger near the magnetic material 1 and weaker away from the magnetic material 1. By arranging the magnetic materials 1 periodically and spaced apart along the height direction, a non-uniform magnetic field with regular distribution of magnetic field strength along the height direction of the column 2 can be constructed between the adjacent two columns 2.

[0054] More preferably, the magnetic materials 1 are arranged more densely near the middle position of the height direction of the column 2 and more sparsely near the two ends of the column 2. By gradually reducing the density of the magnetic materials 1 from the middle to the two ends, the magnetic field between the adjacent two columns 2 is stronger near the middle height of the column 2 and weaker at the two ends. During vibration of the inter-column bracing steel member 3, the vibration amplitude at the middle position is greater than at the two ends, so that the vibration of the middle part of the inter-column bracing steel member 3 can be more effectively suppressed in the non-uniform magnetic field environment with stronger middle magnetic field and weaker end magnetic field.

[0055] Moreover, by arranging two corresponding magnetic materials 1 at the same height as the end of the inter-column bracing steel member 3, the end vibration of the inter-column bracing steel member 3 can be effectively suppressed, thereby achieving rapid suppression of the vibration of the inter-column bracing steel member 3.

[0056] In this embodiment, preferably, the column 2 is provided in a plurality.

[0057] In the steel structure of a factory, many columns 2 are usually provided, and any two adjacent columns 2 can be provided with a plurality of magnetic materials facing each other.

[0058] In this embodiment, preferably, the one-to-one corresponding magnetic materials 1 on two adjacent pillars 2 are set as a group of magnetic materials;

[0059] There are at least two groups of magnetic materials on the same column 2.

[0060] When there are multiple pillars 2 and magnetic materials 1 are arranged one by one between any two adjacent pillars 2 , there are at least two groups of magnetic materials 1 on the same pillar 2 .

[0061] like Figure 2 As shown, when a pillar 2 is located at a corner, it is adjacent to only two other pillars 2, and therefore, two sets of magnetic materials are provided on the pillar 2. When a pillar 2 is located at any other position except a corner, it is adjacent to three other pillars 2, and therefore, these pillars are generally provided with three sets of magnetic materials.

[0062] In this embodiment, preferably, on the same column 2 , the magnetic pole directions of any two magnetic materials 1 in the same group of magnetic materials are set to be the same.

[0063] The magnetic field created by the magnetic material on two adjacent columns 2 has the same magnetic flux lines, so that the inter-column supporting steel member 3 can obtain the maximum change in magnetic flux during vibration. This prevents the magnetic flux lines of different directions from increasing and decreasing during vibration, which would affect the vibration reduction effect.

[0064] In this embodiment, preferably, on the same pillar 2 , magnetic materials 1 belonging to different groups of magnetic materials are staggered and distributed along the circumference of the pillar 2 .

[0065] Since multiple groups of magnetic materials are provided on the pillar 2 , and each group of magnetic materials is opposite to different other pillars 2 , different groups of magnetic materials 1 are located on different vertical surfaces of the pillar 2 .

[0066] In this embodiment, preferably, the magnetic material 1 is distributed in a spiral shape along the height direction of the pillar 2 .

[0067] In order to avoid mutual influence between different groups of magnetic materials 1, on the same column 2, other groups of magnetic materials between two adjacent magnetic materials 1 belonging to the same group of magnetic materials are arranged at intervals. Preferably, other groups of magnetic materials between two adjacent magnetic materials 1 belonging to the same group of magnetic materials are evenly distributed between the two adjacent magnetic materials 1 of the same group.

[0068] In one embodiment, the distance between any two adjacent magnetic materials 1 in the same group of magnetic materials 1 located on the same column 2 is equal, so the multiple magnetic materials located on the same column 2 are periodically repeated along the height direction. Since these magnetic materials 1 belonging to different groups are staggered along the circumference of the column 2, these magnetic materials 1 are distributed in a spiral shape along the height direction of the column 2, and the pitch is consistent.

[0069] In another embodiment, the magnetic materials 1 in the same group of magnetic materials 1 located on the same column 2 are densely distributed near the middle height of the column 2, while the magnetic materials 1 are sparsely distributed near the two ends of the column 2. Similarly, since the magnetic materials 1 belonging to different groups are staggered along the circumference of the column 2, these magnetic materials 1 on the column 2 are spirally distributed along the height direction of the column 2, and the pitch gradually increases from the middle to the two ends.

[0070] In this embodiment, preferably, the magnetism of two magnetic materials 1 adjacent to each other along the height direction on the same column 2 repel each other.

[0071] like Figure 6 As shown, on the same column 2 , the magnetic forces of two magnetic materials 1 adjacent to each other in the height direction repel each other, so that fewer magnetic flux lines pass through the column 2 , and accordingly, more magnetic flux lines are distributed between the two columns 2 .

[0072] Based on the principle that when a metal conductor moves irregularly in a non-uniform magnetic field, an instantaneous induced current will be generated due to electromagnetic induction, and then it will be affected by the Ampere force, and the Ampere force will prevent the magnetic flux in the conductor frame from changing, a non-uniform magnetic field is constructed between two adjacent columns 2. When the inter-column supporting steel structure 3 is in the non-uniform magnetic field environment and vibrates, the magnetic flux in several conductor frames passing through the inter-column supporting steel structure 3 will change. Therefore, an instantaneous induced current will be generated in the vibrating inter-column supporting steel structure 3, and multiple positions on the inter-column supporting steel structure 3 will be affected by multiple Ampere forces in different directions. According to Lenz's law, the effect of these Ampere forces will hinder the movement of the conductor in the magnetic field. Therefore, the effect of these Ampere forces on the inter-column supporting steel structure 3 is to rapidly attenuate its vibration.

[0073] From the energy point of view, the harmful mechanical energy of the vibration of the inter-column supporting steel member 3 is utilized, and through electromagnetic induction, this mechanical energy is converted into electrical energy and then converted into heat and dissipated into the environment.

[0074] Preferably, the steel enclosure structure induction vibration reduction device uses ordinary ferrite hard magnetic material as the magnetic material 1.

[0075] The magnetic permeability of common ferrite hard magnetic material such as ferrite magnetic tile is μ≈5000μ0, and the magnetic induction intensity generated by the periphery thereof is B≈0.05-0.5T (Tesla). The frequency of mechanical vibration of a heavy industrial plant is generally high, and the instantaneous speed of vibration is generally 0.7-1.0mm / s. Taking a 5-meter long common steel structure H-shaped steel HW300x300 member as an example, L=5.0m, the cross-sectional area S=134.8cm 2 The motional electromotive force generated by the member in a magnetic field is about E=BLV≈3.5x10-2-3.5x10-3V, the resistivity of common rod steel member is about ρ=9.78x10-8Ωm, and the resistance of the rod member can be calculated as R=ρL / S≈0.36x10-4Ω. The Ampere force generated is about F=B2·L2·V / R≈1.73-173.6N. Since the member is in a complex non-uniform magnetic field, the actual all Ampere forces are forces in different directions, and the resultant force acts to hinder vibration, and the result of the action of the resultant force is to rapidly attenuate the vibration and achieve the purpose of vibration reduction.

[0076] Based on the above calculation, it can be seen that, since the resistance of the column support steel member 3 is very small, the common ferrite hard magnetic material can be used to construct a non-uniform magnetic field, and the maximum force generated is about 200N. Therefore, the common ferrite hard magnetic material can achieve sufficient vibration reduction effect.

[0077] In actual production, the column support steel member 3 is usually connected by four rod members through the connecting plate 4, as shown in Figure 1 When forced vibration is generated due to equipment operation, the amplitude of the middle part is large, and the amplitude of the edge part is small, which can be regarded as four conductor frames rotating around the axis, as shown in Figure 5 The translation or rotation of these conductor frames in a non-uniform magnetic field generates induced current, and the entire structure is equivalent to a plurality of parallel power supplies. Since the cross section of the rod member is much larger than that of a general wire, and the rod members are connected in parallel, the total resistance of the column support steel member 3 is very low. Therefore, in actual use, the current passing through the column support steel member 3 is larger, and thus the column support steel member 3 can receive greater resistance during vibration to achieve better vibration reduction effect.

[0078] The preferred embodiments of the application are described in detail above with reference to the drawings, but the application is not limited to the specific details of the above-described embodiments. Within the technical concept of the application, various simple modifications can be made to the technical solutions of the application, and these simple modifications all belong to the protection scope of the application.

[0079] It should be further noted that any technically feasible combination of the various technical features described in the above embodiments is possible, provided that there is no contradiction, and the present application does not make any further statement on the various possible combinations.

[0080] Furthermore, any combination of the various embodiments of the present application is possible, provided that there is no contradiction, and should be considered as disclosed by the present application.
